I want to share the most useful tips for a frontend interview at FAANG that helped me to get the job. I will focus specifically on my experience at Meta, but these tips can be applied to other FAANG companies as well. My goal is not to create a comprehensive guide on how to crack the interview, rather I want to provide actionable information that was most helpful for me in the process.
There are a lot of materials available online to help you prepare for the frontend interview. I found the following resources to be the most useful:
- Glassdoor (feedback about an interview process in different companies)
- Pramp (interview mocks)
- Behavioral: Dan Croitor youtube (best behavioral interview videos)
- Cracking the coding interview (book about interviews)
- Tip #1: forget about leetcode, use BFE
- Tip #3: solve as many tasks as you can
- Tip #4: follow HR guidance and ask questions
It's really important to understand the structure of the interview. The frontend interview process typically follows the same structure as a usual software engineering interview:
The HR call is usually a simple phone conversation without video. During this call, the HR representative may ask you simple questions like,
What is the difference between == and ===?
This call is an opportunity for HR to get to know you a bit better and to determine if you are a good fit for the company.
The screening session is usually a 45-minute session where you will be given 1-2 easy or medium JS coding tasks to complete. This is an opportunity for the interviewer to assess your coding skills and to see how you approach a problem.
If you successfully complete the screening session, you will have a prep call with HR where you can ask any questions you have before the next interviews.
The system design interview is an opportunity for the interviewer to assess your ability to design and implement scalable and performant frontend systems. You may be asked to design an application, component, or widget. However, you should focus on the frontend side of the implementation. For example, if you are asked to implement a search widget, you should explain how you will implement autocomplete for the search bar rather than focusing on choosing the right database and server.
The behavioral interview is not different from a usual software engineering interview. This is an opportunity for the interviewer to assess your communication skills and to see how you handle different situations.
