Meta Software Engineer(Internship) interview questions

Applied and heard back a month later. Starting with a interview w/ leetcode easy / med questions. Had a phone call with a recruiter afterwards with some behavioral questions then moved onto round 2 with more of the same, this time a little bit harder. Final round was more of the same, ended in rejection.

The process consisted of two rounds of technical phone screen with different interviewers. Common tagged leetcode questions ranging from easy to medium difficulty. Follow up questions about optimization and efficiency from the interviewer.
