Meta Software Engineer, University Graduate interview questions

Last year, I interviewed for a Software Engineer role. After applying, I received the online assessment (OA) within 3 days and successfully cleared it, which led to the on-site interviews. The on-site process consisted of 3 rounds: two technical interviews (each featuring 2 LeetCode-style problems) and one behavioral round. I was given a total of 2 Medium, 1 Easy and 1 Hard questions. Although I solved most of them, I struggled with one of the Medium problems. I received a rejection a week later, but the experience was incredibly valuable—it helped me identify key areas to improve and strengthened my interview prep for the future.
