I applied online. The process took 2 weeks. I interviewed at Meta (San Francisco, CA) in Feb 2019
Interview
simple and straight to the point. coding challenge, then phone screen. The recruiter was pretty helpful, and the questions weren't that difficult. They probably have a high bar for who they accept, so it's important to make sure you brush up on your data structures before going into the interview process
I applied through an employee referral. The process took 3 months. I interviewed at Meta (New York, NY) in Sep 2019
Interview
I was approached by a recruiter, but she didn't get back to my reply. I later went through employee referral.
I had one phone interview and (although I believed I was good), the interviewer was not confident in advancing me to the next round. I had another follow up phone interview and then advanced to the on site interviews. The results of the on site interviews had some mixed signals in the coding section and I went for a follow up on site coding interview. I received the feedback in one week after the final interview.
My recruiter was very open and communicated every step clearly. I was amazed by how he skillfully managed my process and was ready to help. The whole process was very smooth and I had a very good experience talking to the interviewers and the rest of the team.
Interview questions [1]
Question 1
The coding questions are on average mid level questions. They are not tricky and they are fairly straightforward. Yet, it seems important that you need to solve the coding questions completely to the end, find the optimal solution and cover all the edge cases carefully. For my case, I solved two coding questions in each of the 45 minute coding interviews. The behavioral, system design and machine learning questions were straightforward and manageable.
I applied through other source. The process took 3 weeks. I interviewed at Meta (Washington, DC) in Jan 2019
Interview
Well it was a facebook interview so it was difficult.
For the technical interview, you might need to expect the unexpected.
Mostly prepare for Data structures and algorithms.
It was still a fun experience to try facebook's interview.
