I applied through a recruiter. The process took 3 weeks. I interviewed at Meta
Interview
final interview was very long, had a great experience throughout. everyone was very helpful and friendly. had an easy phone screen and first interviews, maybe because I was scouted by a recruiter. be prepared for the final interview, one on ones with several people from the team
I applied online. The process took 8 weeks. I interviewed at Meta (Menlo Park, CA) in Apr 2019
Interview
Well coordinated, planned, and scheduled but overly drawn out . A lot of robotic, canned questions and tests that had to be answered exactly how the interviewers wanted even if you had a better way to answer it. Interviews felt hollow and impersonal. Also, none of the people I met with had any idea what my role was or how it would interact with theirs and seemed to have been random employees who were suddenly thrown into the interview mix.
Lastly, from walking around the campus it was immediatly apparent that most employees were recent graduates or H1bs so the odds were stacked against me, being a mid career 30 year old who was expecting a livable wage in that region of the country.
Overall a good experience in that I got a free trip to that part of country. My one regret is not asking for a day or two extra for the trip to explore San Francisco and the surrounding areas.
I applied online. The process took 4 weeks. I interviewed at Meta in Jan 2018
Interview
Very quantitative . There was a lot of material covered. Other than that there is not really any difficulties that one should whom studied for the interview should worry about
