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.
Interview questions [1]
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.
The technical round hit me with a classic array manipulation problem: moving zeroes to the end without disrupting the order of non-zero elements. As I tackled it, I felt a wave of familiarity wash over me; I had just practiced a similar challenge on PracHub. The rest of the interview followed a straightforward path, with some easy behavioral questions sprinkled in. Overall, it felt very easy, but I wasn’t quite the right fit for what they needed, so I didn’t receive an offer.
