When I interviewed at Redmond 15 years ago, it was the recruiter who asked me a bunch of techie questions then decided to bring me out for a whole day of onsite interviews. During that I recall it was only a director of SW who asked me some mentally crushing questions about subtleties in how the Windows kernel fiddles with files. As I said, I was a UNIX developer who didn't know those bottlenecks in the Windows kernel. Still he persisted. He did take me for a spin in his awesome BMW sports car after though!

My thoughts on Redmond were that it rains all the time and the inside of the Microsoft buildings is pretty depressing.
