Meta Software Developer interview questions

Recruiter reached out on LinkedIn. Cleared the phone round. Onsite had 2 coding and 2 system design and a behavioral round. Most of the questions were medium/easy leetcode. Except for one interviewer, all the other interviewers were having less than 2 years of experience. I got a reject email from the recruiter after 4 days after the onsite. No feedback or anything. They lacked the courtesy to call me and inform me. Quite unprofessional on the recruiter's part.

Brief, 2 interviews, they were managers, but it is not always the case. I first had a phone call from HR, and they kept updating every other day The interview itself was a hour long, only 1 question, with followups
