I applied through an employee referral. The process took 1 day. I interviewed at Meta in Oct 2017
Interview
A phone interview. He asked my resume at the beginning and introduced himself. Then two algorithm questions. The number of islands and three sums. They also asked my project experiences.
I applied through a recruiter. The process took 2 weeks. I interviewed at Meta in Aug 2017
Interview
Phone screen - the questions weren't crazy difficult, and the interviewer was friendly and helpful. They were pretty late in calling me though, which didn't leave a great impression. It was equal parts coding and behavioral.
I applied online. The process took 1 day. I interviewed at Meta in Oct 2017
Interview
Got an call from my interviewer. Didn't talk much and started coding immediately. Frankly, this year the coding question is a lot difficult, probably because amazon is no longer hiring.
