I applied through a recruiter. The process took 2 weeks. I interviewed at Meta (Philadelphia, PA) in Oct 2015
Interview
They came to campus for OCR. I walked into the interview room, introduced myself. He said hi, then we jumped straight into coding. His question was straight forward and I gave him the optimal solution and coded it up. I was sure to talk through the problem with him as I approached it and he told me he liked my implementation. I'm not sure why I wasn't offered a second round.
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.
