Morgan Stanley Sr. Software Engineer interview questions

They did not give an idea of what is expected in the interview. I was told it would just be a technical discussion and then there were two people interviewing me with coding exercise, system design and questions from everywhere where I don’t have experience with. They were not friendly at all and they made me uncomfortable through the process. They feel like they are the ones that knows everything and the candidates are nothing. Worst interview of my life. They haven’t even responded after the call.
