Facebook’s Interview Process for Data Engineers

Navigating the interview process at Facebook for a data engineering position is a multi-stage journey that tests a candidate’s technical abilities and cultural fit.

Initial Screening – The first encounter is usually a screening call with a recruiter. This is where you discuss your background, your interest in Facebook, and your understanding of the data engineer role. It’s as much about making a personal connection as it is about confirming the basic qualifications on your resume.

Technical Screenings – If the screening goes well, you’ll move on to the technical interviews. These are often conducted over the phone or through a video call and involve solving technical problems in real-time. You can expect questions that assess your coding skills, usually in a language of your choice, and your ability to apply algorithms and data structures to solve complex problems.

Coding test – The coding test is designed to evaluate your proficiency in writing clean, efficient code. It might be on a platform like HackerRank or conducted live with an interviewer. You’ll be expected to write code that not only works but is also optimized for performance.

Onsite Interviews – the onsite interview loop is an intense day that typically includes multiple interview sessions. These are a mix of:

  • System Design Interviews: You’ll be asked to design a system or architecture, which tests your understanding of how different components of a data infrastructure interact with each other and how to scale systems effectively.
  • Behavioral Assessments: These sessions assess how well you align with Facebook’s core values and culture. Expect questions about past experiences that demonstrate your ability to work in a team, lead, and navigate through challenging situations.
