I applied through an employee referral. The process took 1 day. I interviewed at Meta in Mar 2015
Interview
The interview was a phone screen; the first 10-15 minutes asked me about my research, and then I had to code a palindrome detection algorithm. I answered the question eventually, but I had a couple of bugs while writing and this did not seem to please the interviewer, who wanted to ask follow-up questions.
Interview questions [1]
Question 1
Palindrome detection with non-alphanumeric characters
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.

Question 1
Move zeroes in an array to the end while keeping non-zero element order, in place
1 leetcode med, 1 leetcode hard. make sure you know your DSA and leetcode questions. I wasn't able to get an offer bc i didnt complete the second question. Got a reply 2 days later saying they would move on
