Meta Software Engineer Internship interview questions

2 Leetcode questions. One was easy, the other one medium. The interviewer was nice although not very helpful during the interview. He rarely made any comment on my approach or code. After about 1 week of no response, I finally emailed my recruiter who let me know I'd been rejected.

I applied online, and HR emailed me about the opportunity. Then I had two coding testings with their engineers. After that, HR told me that I need additional coding tests, I did it again, 2 weeks late, HR said they can not move on.
