Facebook Data Engineer Interview Process

The Facebook data engineer interview process typically involves the following stages, which are similar to the stages for most tech roles at Facebook:

Phone Screen Round (30-45 minutes)

An initial HR recruiter phone screen is aimed at verifying the background and skills mentioned in your resume, seeing if you have a shot at the job and can be a good fit for Facebook. If the basics check out, you move on to a technical screen.

Technical Screen Round (About an hour)

The technical screen is often a phone screen but can sometimes be an in-person interview. It is conducted by a peer/Facebook Engineer, and you need to solve several SQL and coding problems in a timed environment to get through. You’ll have a simple editor to solve these problems that will not auto-complete or give syntax suggestions. If you clear this interview, you will be invited for a series of on-site interviews.

On-site Round (4 rounds, totaling 4-5 hours)

  • Three problem-solving rounds: In these rounds, they want to test your knowledge of data engineering concepts and technical skills like coding. They want to know your thoughts on the data engineering-related issues associated with the company and how you can help solve those issues. You can expect questions revolving around these topics in the problem-solving interviews.
  • A behavioral round: This interview tests your professionalism, company/role/team fit, leadership skills and ownership, self-awareness, growth, drive, and willingness to be a team player. You can expect questions involving hypothetical scenarios where you need to share how you’d respond. Behavioral interviews also commonly involve questions related to your strengths, weaknesses, and interests. This round becomes progressively more important as we consider more and more senior-level positions at Facebook.
