Microsoft

Answered questions, had calls, and spoke to people. I was also asked questions. Lots of questions and calls, and I spoke to many people. In a nutshell. Indeed.

You receive an email, then a call. You get ghosted, and then you don't get the job. Overall, not a very good experience. Perhaps it's too large of a company?

It was pretty much like every other computer science interview ever. No huge surprises. Just practice your coding, and you should be fine. Practice all day, every day, and also work on your soft skills.
