Morgan Stanley Senior Java Developer interview questions

Contractor position - so contacted by third party recruiter. 2 rounds of interviews both of them were related to problem solving and lasted for 60 minutes. Main focus - Linked list , algorithms , angular ( it was there in my resume)

After applying, you have to clear hackerrank test which is fairly simple. It would have some basic java MCQ and 2 programs. After that I had first telephonic round, which was purely on core Java. After that I had a zoom meeting,, which was a disaster. The interviewer was rude and obnoxious. He didn't even want to repeat questions and had an attitude more like a viva teacher who expects answers to match what's there on his sheet. Morgan Stanley is huge, I was hoping they have more people friendly managers atleast.
