Full stack developers use programming languages, frameworks, and design strategies to develop and maintain websites and applications. With an anticipated job growth rate of nearly 13% in 2021, it is currently one of the most in-demand skills. Full stack developer interview preparation tips can help candidates gain an edge and increase their chances of landing these competitive roles. It is also one of the most satisfying jobs, as reported by USA Today.

If you are appearing for an interview for a full stack developer position, it means that you are already an expert in HTML. Interviewers expect you to be an expert in at least one programming language necessary for the job role for this position.

In this article, we will help you understand how to prepare for a full stack developer interview.We’ll cover everything from the different stages of the interview to full stack developer interview preparation tips. We also share some commonly asked full stack developer interview questions in FAANG companies.

Three Stages of the Full Stack Developer Interview

In most organizations, the full stack developer interview is divided into three segments — introduction, pair-programming, and Q&A.

As a full stack developer, you should be adept at front-end development that uses Java, JavaScript, and HTML. The knowledge of the Ruby program is also desirable. In addition, in-depth knowledge of palindrome functions and data structures will ensure you go a long way in the interview process.

Round 1: Introduction

In this round, you’ll introduce yourself and provide information about:

Your previous role as a full stack developer
Your most preferred programming languages
Ongoing projects

If you are working on any personal projects, discuss your approach, its development, and implementation. Help the interviewer understand your role in the process.

Round 2: Pair-Programming

During this round, you will be asked to write a code for a particular program or API. While working on the code, you should explain your approach to the interviewer.

This is one of the crucial rounds where full stack project interview tips become useful, as you need to showcase your problem-solving skills and implementation ability while working toward a common goal as a team. These situations are generally based on actual problems that you may be required to work on once you are hired.

Round 3: Q&A Round

The Q&A (question and answer) round is held to discuss your achievements, previous experiences, and other job-related aspects. You can expect discussions about the company, job role, and what it entails, making it an opportunity to learn about the organization's functions, business operations, and expectations from a candidate.

How to Prepare for a Full Stack Developer Interview

Besides having an impressive resume, a technical interview for the position of a full stack developer is an opportunity to showcase one’s technical skills. The full stack developer interview preparation tips often focus on three key steps:

Understanding the problem at hand
Finding a possible solution
Explaining and implementing the solution (while showcasing attributes of a well-versed full stack developer)

While this might look short and simple, you will need to do solid prep to understand, solve, and explain any problem or question thrown at you.

Here’s what you should do while preparing for that full stack developer interview:

Full Stack Developer Interview Preparation Tips: Master the Fundamentals

Mastering the basics of stacks is key to cracking a full stack developer interview at any company. Research and review the company’s stacks as a part of your full stack developer interview preparation tips is a good start. Studying StackShare and GitHub repos of a company to find libraries and languages they use is critical for the technical interview round preparation.

Fundamentals of data structures, object-oriented programming, string manipulation, and control flow must be a part of your full stack developer interview prep. The main objective is to assess your ability to code with a reason rather than in-depth preparation. Since most languages have similar constructs, it is not necessary to be a master of every language.

Full Stack Developer Interview Preparation Tips: Practice Live Coding

A common task that an interviewer will assign you is fixing a “broken code.” The full stack developer interview preparation tips suggest that you practice live coding to learn to identify bugs and know how to fix them. Your approach is the key here; in all probability, you will be working on unfamiliar development conditions — integrated development environment or an unfamiliar computer system.

When preparing for a full stack interview,practice without fancy key bindings, custom dotfile alias, or convenient dual-screen setups. Furthermore, it is beneficial to ask which language your technical round will be based on to avoid hassles.

Full Stack Developer Interview Preparation Tips: Prepare for the Take-Home Assignment

You might receive a take-home assignment as a part of your tech interview. This can work to your benefit — you can use Google, Stack Overflow, and the likes, along with your dev station. An example of such an assignment would be “Implement a validator for simple games such as Solitaire along with a test suite.” The implementation of the validator is the primary goal of this assignment.

The deadline for such as task can be anywhere between 4-6 hours to 2 days, depending on the job and task.

Full Stack Developer Interview Preparation Tips: Prepare for the Build Challenge

In a build challenge, interviewers may task you with building a Web 2.0 application with boundary conditions — you must outline the data types you need and functions of your model. They can add further restrictions to minimize your options and test your adapting ability.

To be successful at a building challenge, you should know the intricacies of an application’s stacks, even if you are not well-versed with low-latency networking or database administration.

In order to practice, you can work on a previous project at your last job or a personal project, and as you come across errors, develop an in-depth understanding of the interaction between UI, backend, and frontend, and your approach toward it. These are crucial elements for full stack developer interview prep.

Full Stack Developer Interview Preparation Tips: Prepare Questions; Rehearse Answers

Create your own set of questions on various topics depending on the job role you are preparing for. Rehearsing answers for questions around building strategy, workflow, dealing with changing requirements, and dealing with low or sub-par product specs is an integral part of the full stack developer interview preparation.

Full Stack Developer Interview Preparation Tips: Online Coding Courses

Software engineers can take up online courses as part of their interview preparation for a full stack developer position.

5. How to reduce the load time of a web application?

Reducing redirects, enabling CSS and JavaScript synchronous loading, removing plugins, and optimizing CSS delivery are some of the ways to lower load time of a web application. You can add other factors such as using CDN, reduced image sizes, and lesser images, enabling compression, and others if necessary.

6. What is your understanding of referential transparency?

Referential transparency and opacity are properties of parts of computer programs. You can change an expression or value without impacting the final result. It is a part of functional programming and applicable in the case of imperative programming. It also helps to make your code clearer and build better-defined subprograms.

7. What is your understanding of long polling?

Long polling or HTTP long polling allows a client request to remain open even if there is no adequate information available on the server instead of sending an empty request. When the server receives the desired information, it responds to the client.
