I applied through an employee referral. I interviewed at Meta
Interview
the interview process consisted of a coding challenge. it took around 3 months. referred by employee. coding questions basic algorithmic problems (3 questions in 1.5 hours). pretty reasonable but review before hand so don't get stuck on syntax
3 phone interviews, each for about 45 minutes. First did two interviews and then they asked for the third round. Recruiters very pretty responsive. The process was very standard.
Interview questions [1]
Question 1
general data structure/algorithm question. Interviews were pretty much like other big companies in tech. The process was very standard.
Submitted resume at campus fair, got a technical interview request on campus. Question was slightly convoluted but not technically easy, so it seemed to mostly test the ability to resolve ambiguity through followup Q's
