I applied through college or university. The process took 4 weeks. I interviewed at Meta (Palo Alto, CA) in Oct 2012
Interview
After a phone interview from the recruiter, I had a rather easy Skype technical interview (3 algorithmic questions, answered all of them correctly). Within 2 weeks I was informed that I was approved for an onsite interview in Palo Alto HQ. There I had 4 consecutive interviews (Ninja, Pirate, Jedi, Ninja). Ninja interviews require coding in board practice - quite difficult since if you answer correctly in one of them they ask something else. Jedi was related to my PhD. Pirate was the most difficult one as there were no right/wrong answer and questions were related to database design and overall Facebook feature design. The interviewers were very friendly and helpful. In overall, a great experience!
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.
