I applied through a recruiter. The process took 2 weeks. I interviewed at Meta (Palo Alto, CA) in May 2016
Interview
Got a call through a recruiter. First level technical screen was done by the recruiter. After I cleared this test, the next was a phone screen with an engineer in the team. The whole process was very professional and smooth.
The phone screen had 2 coding questions that I had to solve in 1 hour. They were easy. Read leetcode if you want to crack facebook interviews. I solved both the problems, but my code missed edge cases. I think they want people who can get it right perfectly in the first go(which is kind of expected ). My bad luck.
The technical round for meta was rather straight-forward, living coding of one or two medium difficulty leetcode questions. Asked about how the role was and how interviewee can contribute at the specified role
The interview process was seamless made it to the second stage. The first interview was a phone call from the recruiter which was cool. The second was technical interview with 2 people live.
I applied in-person. The process took 4 weeks. I interviewed at Meta (Dublin, Dublin) in Aug 2019
Interview
it took almost 4 weeks an overall very smooth process. first a phone interview with a recruiter, then a 1-hour online coding with the respective team member and then there was an onsite interview of 4 hours.
