I have worked here before, but these particular interviewers did not know me at all. This was for a quite senior engineer position, though the questions felt like they could/would be asked of anyone. Note that it was senior but not management. Overall I'd call it a tough interview that did not focus on annoying gotcha puzzles and more or less stayed on the topic of reasonably realistic design/coding/architecture matters. I appreciate this, as it won't weed out people who can't handle "brainy" questioning that's more fit for, I don't know what, but not actual engineers. There was also no "do this hard thing in 2 hours on your own" types of challenges, which I also appreciate. Somewhat annoying was the lack of time to explore each question, as 45 minutes was not enough given the pace of discussion. This, of course, depends on the interviewee, but I was having healthy discussions, not hemming and hawing.
