Meta Developer interview questions

Overall the process is very fast and all the interviewers are very nice. It take 3 weeks to finish all the interviews (include christmas and new year holidays). I took 1 phone screen + 2 coding + 1 system design + 1 research interview( for PHD ). All the coding questions are the common questions you could meet them easily when you read " crack the coding interview" or surf GeeksforGeeks.com, and there was no brainteaser. The system design problem is kind of hard, because there are no right or wrong answers. I think I didn't perform that well in this round, because I am not very experienced in large system design. The research interview mainly focus on my research project, and we also had a small coding part, I did well on that. Honestly, I am kind of surprise that I did not get offer from Facebook, maybe there were some requirements that I did not match.

I told them that I was on deadline with another offer from another top-tier Silicon Valley company, but even without special fast-tracking we managed to finish everything extremely quickly. On campus screen to onsite interview done within the same week and got my offer shortly afterwards!
