I applied on the university careers portal. Received an online assessment link. Did the OA. After a week the hiring manager directly contacted me for an onsite interview. The manager was very nice to me. He took me to visited the whole office and walked me through some behaviour questions. Then a senior developer asked me questions about my CV's projects and experiences. Another developer went into the room and started to ask me concurrency questions in Java and a Leetcode hard level question (which I found out after the interview). He was quite mean to me and refused to give me any hints. I have no idea why he was so mean to me. I felt relieved walking out of that building. I received the rejection a week early.
