Arrogant interviewer in the first round. Answered both questions fully. He was incompetent and arrogant, was constantly asking dumb questions. Just because I was 2021 graduate he was behaving as if I am not allowed to be giving sde-2 interviews. Came 20 minutes late, did not give any extra time, was asking dumb questions still answered both questions, gave brute force optimal + implemented + passed all test cases.
