I applied through an employee referral. The process took 4 weeks. I interviewed at Meta (New York, NY) in Nov 2016
Interview
I had two technical interviews with Facebook. Both interviewers asked me a few behavioral questions first such as why facebook and then move into coding challenges. I gave two solutions to one problem during the first round and passed it. For the second one, I only managed to solve one quite hard problem and failed it unsurprisingly.
Overall, the process took a little over two weeks, which felt a bit longer than I anticipated. After a quick screening, I went through two technical rounds focusing on coding and DSA concepts. One of the questions was a classic palindrome check; mid-way through, I realized it was something I had practiced on PracHub just days earlier. The final step was a casual behavioral interview. I was relieved to get an offer shortly after, which I happily accepted.
