I applied through an employee referral. The process took 2 weeks. I interviewed at Meta in Sept 2021
Interview
I was asked three questions on one round, the hardest one was leetcode1284. Then the interviewer asked other two questions, I gave the answer verbally. He didn't ask more, then we discuss the team and project that he was working on.
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
