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.
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 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. Cracking a full stack developer technical interviews basically requires the following three 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 preparation 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:
Master the Fundamentals
Mastering the basics of stacks is key to cracking a full stack developer interview at any company. Research and review of the company’s stacks is a good start to a stack interview prep. If it’s a Ruby shop, you would also need to know how it works before the interview. 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.
Practice Live Coding
A common task that an interviewer will assign you is fixing a “broken code.” You will need to identify the bugs and fix them. This is used to ascertain if you can identify code blocks, read test specs, and make changes wherever necessary. 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.
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.
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.
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.
Online Coding Courses
Software engineers can take up online courses as part of their interview preparation for a full stack developer position. Receiving guidance from industry experts and senior software developers who are familiar with the degree of preparing for a full stack developer interview can prove beneficial in clearing the interview.
Technical interview preparation specialty courses are available in abundance, where former employees of various companies give the requisite training to candidates to help crack interviews. Bootcamps can also help coding engineers to acquire in-depth knowledge.
Topics to Prepare for Full Stack Developer Interview Question
Irrespective of whether the job role is front-end framework intrinsic or backend, you should be well-versed with the basics. Topics you must prepare for include:
- Angular JS
Other Programming Languages:
Basic Database Systems:
- AI or Machine Learning
- .Net and asp.net Framework
- Linux Command-line
- Data Structures
