Personally, my biggest issue with interviewing at large companies like these by people whom you aren't necessarily going to be working with, is that not everyone is in a position to interview people. I personally hate interviewing other people and having to be responsible for their futures. I was never trained for it, and I don't want to ever deal with it. I just want to code and make sure the product I'm working on is coming along smoothly.
I've had countless interviews where I could immediately tell upon entering the room that the interviewer does not want to be there at all. It's a lose lose situation. For me, because I get demoralized instantly, and he's already got a chip on his shoulder for having had to do this in the first place. Everything I say going forward from that point on is an uphill battle.
I think only managers/very few people who are truly trained should interview people as that is kind of the essence of a manager's job--making sure they have happy, solid team. I don't even mind the technical questions. I just want to be in a room with someone who is actually potentially excited having me there. Not grilling me in a depressed fashion
