I applied through a recruiter. The process took 5 weeks. I interviewed at Meta (Menlo Park, CA) in Dec 2016
Interview
I contacted a recruiter via email that I received by a former Facebook employee. She followed up asking some standard questions about my experience and availability with a phone screening that lasted about 15 minutes. I then scheduled a phone interview with an engineer in the Instagram even though I was only applying for positions in Europe. The question was pretty difficult and it was more of a mathematical problem than a computer science questions. I studied a lot of algorithms and data structures exercises. The engineer helped me getting the idea on how to solve the problem but I was running out of time unfortunately.

Question 1
It was a mathematical questions about finding the greatest number (but less than the given number) by reordering the digits in the number.
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.
