MSCI Senior Software Engineer interview questions

Online assessment round followed by technical rounds. I got the feeling interviewer didnt like me for some reason, I was asked to write code for minimum cost and certain choices for selection, I suggested a recursion algo, interviewer wanted me to do it the iterative way, managed to get 2/3 test cases clear, didnt give me any hints or any feedback, proceeded to ask me questions on tech stack that were not on my resume, Kubernetes, snowflake, nginx. Question was how do you mb/gbs worth of data with user, I suggested sharing pre-signed url(AWS in my resume), he had no idea what S3/pre-signed url was he wanted snowflake integrated solution. Also the HRs didnt bother to give feedback on my interview. I had given interview a year before, where they would dig into basics and fundamentals of code and lang and ask questions that are general, not specific their own personal tech stack. But this time there was a huge difference, interviewer asked questions based on the stack they were using not what's mentioned on candidates resume.

Multiple rounds, HR reached out on LinkedIn, 1. HR phone round, 2.-3 two rounds of technical interview, 4. Team Lead and in my case another Team Lead. The project that would have been interesting, was not available by the end of the process and the other one did not seem interesting to me.
