I applied online. The process took 1 day. I interviewed at Meta (New York, NY) in Feb 2016
Interview
Recruiter reached out and scheduled two phone interviews. The interviews are all about solving algorithmic problems. After solving the problem, I asked some questions. Got feedback and offer in a week.
The process was fairly smooth - good information provided for preparing for the interview & proper expectations were set before the interview regarding they day's schedule. My experience with both recruiting and engineering was very good.
I applied through a recruiter. The process took 6 weeks. I interviewed at Meta (Menlo Park, CA) in Sep 2016
Interview
The interview process was good and smooth. I had 2 phone interviews. The Facebook office is really mind blowing. My interviewers were really nice. 5 onsite interviews - 2 system design and 2 coding and 1 behavioral interview with a small programming question. I think my system design was not as good as the coding ones but despite that I think because of my overall performance I got the offer.
Interview questions [1]
Question 1
Practice questions on leetcode. They pay a lot of attention to coming up with optimal answers. I had questions on data structures, algorithms and dynamic programming.
