Meta Software Engineer interview questions

First I had a quick initial phone screen with the recruiter. Was asked basic questions about my previous experiences. Then I was scheduled for a screening interview. I was given 1 Leetcode Hard heap related question that I didn't solve optimally.

It was good. 3 rounds. 1 OA, 1 Full Loop, 1 Follow up. I did three technicals, 1 behavioural. Had to grind a lot of leetcode but worked out in the end. Interviewers were nice
