I applied online. The process took 2 weeks. I interviewed at Meta (Los Angeles, CA) in Jan 2015
Interview
The interviewer was very cool and he asked me about myself and my projects. He also asked why I want to choose facebook and then we started coding round, which took nearly 45 minutes.He mainly focused on performance tuning of algorithms.i.e How fast we can make spontaneous decisions for an algorithm to run fast.Overall, it was very good 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.
