How to Continue Learning After Graduating from a Software Engineering Bootcamp

A software engineering bootcamp provides structure, curriculum, and periodic assessments to make sure you’re learning effectively. However, it can be difficult to learn consistently once you graduate from a bootcamp, since you’ll have to define your own goals and schedule. You’ll also need to find ways of holding yourself accountable.

In this post I will share strategies on how to effectively continue learning after graduation. At the close of the post you will find links to several resources to improve specific software engineering skills. 

How to Continue Learning Effectively

A lot of the strategies discussed below may be familiar to you since you’ve likely deployed them during bootcamp. They will be equally effective in your postgraduate journey. 

Set Goals

Bootcamps set concrete goals spread out over an entire program. Every student is expected to learn foundational skills. But once you graduate from a software engineering bootcamp, your goals will likely vary from your peers. For example, you may want to look for front-end roles over back-end roles. Or, the types of companies you want to work for may be different from those of your peers. It’s important to define what your goals are to effectively plan out your job search strategy and learning schedule. Make decisions about the types of roles you want to land, as well as what you want to continue learning about. 

Determine Your Baseline

Bootcamps are effective because they are heavily focused on practice. Practice does not end once you graduate. You will especially need to focus on interview practice and coding assessment practice. You should continuously apply whatever you are learning post-bootcamp to gauge your skill levels and identify areas of improvement.

For software engineering job readiness, use services like Pramp, Meet A Pro, or for mock job interviews. These platforms usually allow you to get detailed feedback from your interviewers (unlike real job interviews). Interview practice is crucial for success. If you don’t use one of the services mentioned above, find a friend to practice with. Prep answers to commonly asked software engineering job interview questions. Also, prep answers to general interview questions

Make a Plan and Stick to It

Continuous software engineering skills development is key to your success. Once you have identified the skills you want to learn or sharpen, create a schedule for learning and practicing. For example, one of our alumni wanted to learn Java on his own while also practicing the skills needed for job interviews. The following is a schedule snapshot of one of his weeks:

Be Consistent

Mastering new skills requires consistent effort and self-reflection. Regular practice and review are key to solidifying your understanding and developing intuition.

Establishing a consistent study and practice routine is crucial for building good learning habits. Setting dedicated study and practice times throughout the day helps train your brain to focus effectively. It also ensures you are making consistent progress towards your goals.

Take Notes

Make note of new concepts you are learning and write down questions about the concepts that you find difficult. This is especially helpful when learning complex and complicated concepts like data structures, algorithms, and system design. Writing out the processes by hand will improve your retention and understanding since it will force you to think through every step.

Use Active Recall and Spaced Repetition

Active recall, also known as active retrieval or practice testing, is a learning strategy that focuses on retrieving information from your memory instead of passively absorbing it. By actively struggling to retrieve information, you engage your brain in a deeper way and foster deeper connections to the learned information. 

Spaced repetition refers to the process of revisiting things you’ve learned or practiced in an increasing cadence to make sure the concepts stick in your mind. In the case of programming, you’ll end up using various foundational concepts over and over again. However, for certain uncommon concepts such as graph traversals, you’ll have to be mindful of revisiting them and practicing so you don’t forget how to apply them.

Use Analogies and Metaphors

Using analogies and metaphors can help unlock a deeper understanding of problems and strengthen information retention. A vivid imagination fuels this process, as it allows you to connect abstract concepts to concrete experiences. When taking notes, actively rephrase ideas in your own words and forge connections with your personal knowledge by drawing on past experiences or relevant examples.

Track Your Progress

Tracking your problem-solving and learning journey can be a powerful motivator. It can also help foster accountability and inform future planning. Use a spreadsheet to maintain a running log of solved challenges and completed projects for a clear picture of your progress. Conclude each day with a review, adjusting your tasks for the following day. This practice can sharpen your focus, streamline your workflow, and help eliminate unproductive indecision.

Try Different Perspectives

When you get stuck on a problem, try approaching it from a different perspective. There are usually multiple ways of solving a coding problem. When using websites like Leetcode, make sure to read up on alternate solutions from the discussion section to learn new concepts, frameworks, and approaches.

Don’t Forget to Rest

Your brain requires rest to embed information into your long-term memory. Not thinking about a problem you’re stuck on also engages your diffuse mode of thinking, which can help provide you with a creative breakthrough. Make sure you get plenty of sleep, as it’s crucial for long-term memory formation and mental health. Account for rest in your day-to-day life in order to sustain motivation and prevent burnout.

If you want to learn more about the above strategies and why they work, check out the book A Mind for Numbers by Dr. Barbara Oakley.

System Design Overview for Bootcamp Grads

Students in software engineering bootcamp programs usually build small-scale projects that require, at most, a few weeks of work. These projects don’t have to account for long-term considerations such as maintainability, scalability, and security. But when companies build applications they have to take into account several factors.

System design is the process of designing an application or service while taking into account user needs along with the product and business requirements. There are various types of systems that you may have to design as a software engineer. But the following three are the most common ones you’ll likely work on, especially earlier in your career:

  1. Application: A full application that addresses user needs, such as a URL shortener. It’s not common for an individual to design, develop, and maintain a full application at a company (unless it’s a very early-stage startup).
  2. Application feature: A specific feature addition or modification to an existing application, such as designing the feed for a social media application. Individual contributors are generally expected to work on these. 
  3. Microservice: An application that’s not user-facing and is only used to facilitate the functioning of the overall system. For example, you may be asked to design or suggest a key-value store suitable for an existing system.

You need to consider both functional and non-functional requirements when designing any system. Let’s explore the differences between these two types of requirements using a URL shortener service such as as our example.

System Design Overview: Functional Requirements

Functional requirements define what a system is supposed to do or the specific features it must provide the users. 

A URL shortener service may have some or all of the following functional requirements:

  • Shorten URLs: The system must be able to take a long URL as input and generate a short URL.
  • Redirect: When users access a shortened URL, the system must redirect them to the original long URL.
  • Customization: Allow users to customize the shortened URL or provide an option to generate a random one.
  • Analytics: Track the number of times each shortened URL is accessed and provide analytics for users.
  • Expiration: Provide an option to set an expiration date for shortened URLs.

System Design Overview: Non-Functional Requirements

Non-functional requirements define the qualities or characteristics of the system. These include performance, reliability, and usability, rather than specific functionalities. 

A URL shortener service may have the following non-functional requirements:

  • Performance: The system should generate shortened URLs and redirect users quickly to ensure a seamless user experience.
  • Scalability: The system should be able to handle a large volume of URL-shortening requests and redirections efficiently, especially during peak usage times.
  • Reliability: The system should be highly available and reliable, with minimal downtime or service interruptions.
  • Security: Ensures that the system is secure and resistant to attacks, such as URL manipulation or injection.
  • Usability: The user interface should be intuitive and easy to use, allowing users to quickly shorten URLs and access analytics without confusion.

This article does a great job of explaining various non-functional requirements if you want to explore more.

When Should You Design Complex Systems?

Although it’s important to consider various requirements, tools, and technologies when designing systems, it’s equally important to not over-engineer systems. You’ll generally have some requirements guidelines when working on a team that maintains a product or service with existing users. System design interviews also have fairly good requirements (or at least the interviewer will nudge you towards desired requirements).

However, when you are developing a product or feature from scratch, it’s important to prototype quickly and gather feedback before tacking on a bunch of non-functional requirements. For example, used Google Sheets as their backend in the beginning to scope out their idea before scaling it. If you design a large-scale system without considering user needs, you’ll end up with a beautiful, scalable system that no one uses.

In general, it’s better to start with simple design, tools, and technologies before designing for scale. 

System Design Overview: Foundations

System design study resources cover tons of topics, such as scalability patterns, load balancers, and caching. But they are usually geared towards people who already have some experience with application development. 

If you’re just starting out, it’s important to be aware of a few key concepts and ideas. We’ll be covering the following topics in the remainder of this article:

  • Relevant computer components
  • Single machine problems
  • Distributed systems

Relevant Computer Components

relevant computer components

You’ll encounter various terms like Content Delivery Networks (CDN), load balancer, cache, proxy, database. All of these terms refer to a computer or a network of computers running specialized applications.

The central processing unit (CPU) is often considered the “brain” of the computer. It mainly executes instructions and performs calculations required to run programs and processes.

Random-access memory (RAM) is the computer’s short-term memory. It is usually significantly faster than long-term storage. Temporary data and program instructions for the CPU are stored on the RAM.

Storage devices provide long-term, persistent storage for data, programs, and system files. Unlike the RAM, storage devices retain their data even when the power is turned off. They also have a much higher capacity than RAM.

The components are prioritized based on the type of application being run on a computer. For example, a database will likely have a much higher storage capacity than a server that processes user requests. 

Single Machine Problems

request response cycle

You have probably designed and built a system like the above in your bootcamp program. It’s a standard structure that allows you to serve millions of users. But notice that all the requests and responses are being handled by a single server. And all of the data is being stored on a single database.

Single machines can cause issues down the road. The following are some of the issues that may crop up:

  • Performance limit: A single server can host a limited number of CPUs, RAM, or storage. If you have a lot of requests, a single server simply won’t be able to handle them.
  • Expensive component upgrades: More powerful CPUs and larger capacity RAM or storage devices can become very expensive. It’s often more efficient and cheaper to get additional systems.
  • Scalability limit: The above two issues limit the scalability of the system. The server will either stop serving requests or it’ll be too expensive to upgrade it.
  • No redundancy: If either the server or the database fails, it will cause a service outage for all of our users.
  • Low availability: Availability refers to the proportion of time that a system is functional and working. If we have to upgrade the server or the database, we would have to suspend our service. 

So how can we solve these issues? That’s where distributed systems come in.

Distributed Systems

A  distributed system is a network of multiple independent computers (often referred to as nodes or hosts) that work together to achieve a common goal. You’ll have to configure how these computers communicate with each other when designing systems. 

Although distributed systems address the issues with single machines, they introduce issues that need to be taken into account when designing systems. 

Engineer Arnon Rotem-Gal-Oz described several fallacies of distributed systems (i.e., we can’t assume the following statements are true in a distributed system):

  • The network is reliable
  • Latency is zero
  • Bandwidth is infinite
  • The network is secure
  • Topology doesn’t change
  • There is one administrator
  • Transport cost is zero
  • The network is homogeneous

You’ll learn several system design patterns to address these fallacies but they aren’t often stated explicitly in study resources.

Now that you understand the foundations of system design, you can start preparing for system design interviews. You’ll find several resources in the linked article that will provide guidance on what to study.

System Design Interview Overview for Software Engineers

If you have looked into the software engineering interview process, you may have come across something called a system design interview. These interviews tend to be very different from the usual coding interviews.

In this post we will look at why interviewers hold system design interviews, the expectations they have for job candidates, and how to prepare for this type of interview.

But first, we need to understand what functional and non-functional requirements are in a software system and how they should be considered in the design process.

Functional and Non-Functional Requirements

Let’s say you’re building an app where users can post and share images. What functions can users perform on the app?

A user can register and sign in on the app. They can post, share, and comment on images. All of these functionalities are user-focused.

Functional requirements define the specific functionalities, features, and capabilities that the app must provide to meet the needs of its users.

But in addition to these functionalities, the app needs to perform well, be reliable, and securely store user information. Non-functional requirements describe the qualities and characteristics of the system that are not directly related to specific behaviors but are critical for its overall effectiveness.

It’s critical to consider both functional and non-functional requirements when designing and building software.

What is System Design?

System design refers to the process of designing an application while taking into account both the functional and non-functional requirements. It involves making high-level decisions and choices regarding the structure, components, interactions, and behavior of the system.

The System Design Interview Process

In system design interviews, you will generally be asked open-ended questions with vague requirements. You’ll have to collaborate with your interviewer to figure out which qualities and characteristics to prioritize while designing your system.

Unlike coding interviews—where you may have to do algorithm challenges or build apps to specifications—system design interviews have no correct solutions. You will have to justify all of your design decisions in the context of the functional and non-functional requirements while also comparing alternatives.

A typical system design interview will usually follow this format:

  • The interviewer asks the candidate to design a system
  • The candidate then does the following:
    • Clarifies requirements
    • Does back-of-the-envelope calculations
    • Establishes scope of the design
    • Defines a data model
    • Proposes a high level design
    • Defines the APIs for the system
  • The candidate and interviewer discuss details, trade-offs, and extensions

Generally, the interview is 45-60 minutes long so you won’t have time to dive deep into every aspect of the system. This is why it’s important to communicate with your interviewer about the areas you should be focusing on. For certain problems, they may ask you to focus more on the data model and what kind of database you’d use. For others, they may ask you to define your APIs in detail and describe how they would communicate with each other.

Interviewers are generally looking to assess the following skills:

  • Fundamental system design concepts
  • Requirements clarification and analysis
  • Well-reasoned decisions
  • Trade-off considerations
  • Collaboration
  • Communication

These aren’t in order of importance since different interviewers may prioritize different skills based on the job description, role level (IC3 will get easier problems than IC6), and their own experiences.

System Design Study Resources

A system design interview may seem impossible to study for since there are so many topics that can be covered. But thankfully, there are some fundamental concepts that will help you to get through most of the junior to mid-level interviews. Once you’ve got those down, you can read up on real system design on company blogs or research papers.

Below are some additional resources to help you learn how to excel in the interview:

For practice problems:

You should ideally try designing and building some complex systems yourself to see how all the pieces fit together. Starting with simple data pipelines or simple microservices may be helpful.

But the free resources (except for the books) mentioned above should give you a solid system design foundation which will allow you to understand most of the system design interview questions and walkthroughs you may encounter.

It takes time to get really good at designing systems. You will learn new concepts, tools, and techniques throughout your career which will influence your unique way of designing systems. 

For your interviews, focus on understanding the fundamentals, prepare in advance, and do practice interviews on sites like Pramp or Best of luck!

Demystifying AI and ML: An Intro for Bootcamp Grads

ChatGPT catapulted AI tools to the forefront of the public consciousness when it reached 100+ million weekly users last year. Several more apps like ChatGPT have since been launched, such as Bing Copilot and Bard. Although these services can be helpful for software developers, most of the time they’ll use other tools or work with technologies that are in a completely different category.

Over 70% of developers are already using or plan to use AI tools in their development process according to the 2023 StackOverflow survey. The same survey shows that the overwhelming majority of developers (75%+) have a favorable or highly favorable view towards using AI tools as part of their development workflow. 

In this blog post we will be going over what developers are using these tools for, which tools they are using, and how machine learning fits into the development process in companies.

Artificial Intelligence and Machine Learning

Before we dive into what kind of technologies and processes developers use in their day-to-day work, it’s important to understand the difference between artificial intelligence (AI) and machine learning (ML).

Artificial Intelligence

Artificial intelligence describes any computer program that performs tasks that require human intelligence, such as speech recognition, reasoning, perception, and problem solving. John McCarthy, a Turing Award-winning computer scientist and one of the founders of the AI field, said, “AI is the science and engineering of making intelligent machines, especially intelligent computer programs.”

Machine Learning

Machine learning is a more specific term that describes a field of study concerned with the development of algorithms and statistical models that enable computer programs to perform human-like tasks. The core idea behind ML is to use large datasets to identify patterns and learn from them to perform specific tasks. IBM has a good video on the differences between AI and ML that will provide further clarification.

You may also come across the term “Deep Learning” which is a subset of machine learning. We won’t go into it here but if you’re curious, 3Blue1Brown has an excellent video on how neural networks work.

AI in Software Engineering

Software engineers or developers work with AI based technologies in two key areas: development workflow and product feature development.

Development Workflow

Development workflow refers to the processes used to plan, develop, test, deploy, and maintain software products and services. Tools like GitHub Copilot can significantly speed up these processes since they can be trained on specific codebases on top of having insights from billions of lines of publicly available repositories. Having a tool that can provide suggestions and answer questions based on the current project and context can drastically improve the developer experience. In fact, over 70% of developers say AI coding tools will allow them to write better quality code, produce more code, resolve incidents faster, and collaborate more effectively according to a 2023 GitHub Survey

The AI tools used for improving developer experience are usually available off-the-shelf. These tools still need to be trained on the existing codebase for the best results but they don’t require a significant amount of developer work hours. Developers can quickly get up to speed on the basics of these tools and start incorporating them into their workflow to boost productivity since they don’t require any specialized skills.

Product Feature Development

Companies are constantly looking to improve their products by offering novel features. Product features that incorporate advanced ML algorithms can give companies a competitive edge by providing a better customer experience. 

For example, the following diagram gives an overview of how Netflix incorporated an ML model to improve search results for users:

You can read about how this model works in the “Augmenting Netflix Search with In-Session Adapted Recommendations” research paper.

A team needs to have people with various skills in order to develop and maintain a system like this since the feature may require custom algorithms, infrastructure, and code. Working on these systems usually requires knowledge of machine learning and MLOps. 

Where to Go From Here?

If you want to build AI systems and not just use AI tools, you’ll need a solid theoretical foundation and practice building applications or creating infrastructure. Here are a few free courses to get you started on your journey:

Logan Miller: Technical Consulting to Software Engineer

Logan Miller, a July 2022 Software Engineering graduate from Flatiron School, spent 5 years working as a pre-sales engineer for a technical consulting firm and another year in Iceland earning a Master’s degree before deciding to switch career paths into tech.

He shares his journey from consulting to tech – with a stop in Iceland – below.

Early Exposure To Tech

Logan Miller grew up around tech. From his early childhood, it was almost always nearby, either through family or the gadgets themselves, and credits this early exposure with his interest in the field.

“Many of my closest friends are in tech, my mom was in tech, and just growing up around computers and technology had a huge influence on me,” he said. “I was like 11 and started messing around with HTML.”

It wasn’t until he was pursuing a Bachelor’s degree in European History at university that an accidental class enrollment led him to pick up formal programming for the first time. 

“When I was a freshman at Pace University I somehow found my way into a senior-level game design class (don’t ask – I barely even know how it happened),” he explained. “It was pretty daunting when I found out we were going to have to actually program things in C++ considering I didn’t even know what javascript was. I leaned on pretty much everyone I knew to get through it – friends, mom, girlfriend’s dad – anyone who knew anything about coding was sure to hear from me at random hours with random questions.”

Technical Consulting By Way Of Iceland

After graduating, Logan worked as a technical writer and pre-sales engineer for a technical consulting firm in New York. He recalls having the opportunity to work with “impressive people,” but ultimately felt that the work lacked meaning.

“I spent a lot of time working on documents that were ten, twenty, ninety pages in length just skimming for compliance reasons,” he said. “I never really enjoyed what I was doing in a way that would make me, for example, actually want to work all day on a Saturday or something.”

It was the onset of the COVID-19 pandemic in 2020 that made Logan, like many others, rethink his career and path in life. Unsure of what to do next, he applied to the University of Iceland and was accepted. 

“I didn’t feel like my career was going the way I wanted it to and applied on a whim […] because it was essentially free,” he explained. “My intention with grad school in Iceland was to try a few different classes and see what stuck.”

Logan continued to work remotely for the US-based technical consulting firm while attending the University of Iceland. It was during his time in the land of ice and fire that his interest in computer science reignited. 

“Some of my friends [at the University of Iceland] were in computer science programs so I would see what kind of problems they were working on and languages they were learning. It was a lot of fun just messing around with logic and talking about the kinds of bugs and problems they ran into.”

Committing To Changing Careers

Logan left Iceland and returned to the states in July 2021 with his eye set on a career in software engineering. He highlights the field’s range of opportunities as one of the reasons he decided to pursue the field. 

“There aren’t a ton of career paths out there that allow you to land a job in almost any company or vertical, but you can find a Software Engineer who works for Whole Foods just as easily as one who works for the Department of Defense,” he said. “It allows for so much creativity and opportunity since you get people from all walks of life and interests working at places they enjoy.”

After testing the waters with a short online course in Python, Logan applied to Flatiron School’s Software Engineering program.

“I felt that I should take it seriously and make an investment into changing my career. I knew that I wanted to go all in and see how I compared to my peers in a high-paced environment.”

His Experience At Flatiron School

Logan enrolled in Flatiron School full-time and joined a cohort of other students. His classmates and the community they built together, he recalled, were his favorite part of the program.

“Hands down the best part of the Flatiron School program is the people that you spend each day with and watching them grow as programmers,” he said. “There is a real camaraderie with your cohort and you’ll be surprised at how often you’re spending late nights just talking, working, and hanging out with these people you never knew until a few weeks ago.” 

But, the accelerated course was not without challenges. The speed at which the program covered material was intimidating, Logan recalled, but manageable. 

“As long as you trust in yourself, study, and lean on your teammates and cohort instructor you will be totally fine.”

The Job Search

Logan graduated from Flatiron School’s Software Engineering course in July 2022 and jumped right into the job search. The next six months, he admitted, were difficult at times. 

“My job search [was] a rollercoaster. There will be a lot of ups, downs, hopeful moments, tragic defeats, and everything in between.”

Throughout his tumultuous job search, however, Logan had his Career Coach Tracie Mazzu to support and cheer him on.

“It’s nice to have a career coach on your side that can provide advice and a wealth of experience to help you get through everything,” he said. “I started off doubting how much I would get out of a career coach as it just seemed like an additional chore to do but once my coach helped me redo my resume it became abundantly clear that I didn’t know as much as I thought I did.”

Working In Tech

Logan accepted a Lead Developer role with My.Suit in December of 2022. So far, he has only good things to say about his new field. 

“I’m loving it. It’s awesome to be working with something that you enjoy and solving problems that no one else can. There is a ton of freedom and opportunity for you to explore and learn new things each day. The pay doesn’t hurt either.”

His takeaway from his Flatiron School experience is one of self-determination.

“Nothing in life will ever be handed to you. You need to take it and put in the time and effort to make whatever goals you have a reality. Just keep pushing and have fun!”
