Interview Process of a Front-End Developer at FAANG+ Companies

Before moving on to decoding what an ideal front-end developer interview preparation strategy looks like, let’s first understand the interview process at FAANG+ companies.

While framing your front-end interview preparation plan, make sure to give enough time to prepare for each round. The process at FAANG+ companies comprises three main rounds that include:

  1. A Recruiter Screen - A preliminary round where a recruiter will ask you about your interest in the position, skills and experience, and compensation details.
  2. A Technical Phone-Screen - The initial coding round where a hiring manager will ask you questions around coding and algorithms. Front-end developer interview questions asked in this round are majorly around data structures and algorithms.
  3. The On-site Interview - The final round comprises a series of 3-4 interviews in coding, systems design, and behavioral. You’ll also have a round specific to front-end engineering where interviewers will ask you questions specific to front-end development. All in all, you’ll be asked some front-end coding questions, behavioral questions, and questions on distributed systems.

A 6-Step Strategy for Front-End Developer Interview Preparation

A strategy is considered optimal if it includes all the elements required to nail a front-end developer interview. 

Front-end developer interview questions test your problem-solving and analytical capabilities. Answering these questions requires diligent and consistent practice. At Interview Kickstart, we focus on helping students significantly improve their problem-solving skills and take their careers to the next level by crashing technical interviews at the biggest tech companies.

1. A thorough brush-up on front-end concepts

Your front-end developer interview preparation should include concepts specific to front-end development. This is aside from being adept with data structures and algorithms.

Recruiters will ask you front-end-related questions in the Technical Phone Screen round as well as the On-site interview. While the Technical Phone Screen round will have mostly theory-based questions, the On-site interview will involve answering more in-depth questions in front-end engineering.

2. Start your prep at least 8-10 weeks before your interview

Starting your front-end developer interview preparation well in advance, at least 8-10 weeks before your interview, is extremely important if you wish to prepare all the important concepts adequately and beat the competition.

While planning your front-end interview preparation, allocate at least 4-5 weeks to cover concepts in core data structures and algorithms. Devote a week or two brushing up on front-end concepts and 1-2 weeks for distributed systems design.
