Meta’s interview process consists of the following steps:
Call with a Meta recruiter
Technical phone screen (and possibly a second technical phone screen)
Onsite interviews
Meta's technical phone screen is a 45-minute coding interview that focuses on data structures and algorithms.
At the beginning of the interview, your interviewer will ask you a question or two about your resume and recent work that you've done. This portion will take 5 minutes, and how you answer these questions doesn't meaningfully factor into the interview's outcome - they are just meant to break the ice and get you talking. The part that matters is the technical portion.
