Morgan Stanley Summer Analyst - Technology interview questions

2 back to back 45 minute interviews with different managers. First one asked me an odd leetcode like question with the solution only being brute force so it got me as I was trying to optimize it, wouldnt give hints when I asked. Second interviewer was nice but a bit unprofessional, swearing during the interview and whatnot, spent most of it talking about himself, told me "id hire you on the spot but Im not hr so I cant say that yet". Waited 2 weeks then got rejected. He also asked me a non programming technical question.
