MB Bank AI Engineer/DS interview questions

Amateur. arrogant. insolent. I was invited for 1500 interview and arrived at 1450 sharp. Arrived when an ongoing interview was in place and another early bird waited outside which was when I felt something was odd. Then, I realized they weren't punctual at all, I was gonna have a 1500 interview at 1600 at the bare minimum. So, I waited for exactly 30 minutes and left. No apology. Just pure insolency.
