I applied through a recruiter. I interviewed at Meta in Mar 2018
Interview
Phone screen, everything was all usual. First answered the question with LinkedList approach, interviewer says yes works but LL uses extra memory to save pointer so i revised my logic to use array with a circular queue mechanism. Interviewer was pleased (i assumed it wrong). 2 days after phone screen, got the dreaded email.
This was my second phone screen in 2 years at FB, one thing is for sure you need to give the best solution in one shot, no going back and forth. They hire bots who knows 1000+ question on fingertips from leetcode./topcoder/blah blah...
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.
