> I can't tell you about other companies, but ours is pretty straightforward: you tell us what your strongest areas are, we'll give you interviews that line up with those areas. There's no strict guarantees and you should expect a spread of different questions, but whatever it is that you're good at, expect us to offer you a chance to show us that you're good at it.

My one experience with getting to a Google onsite is that, despite repeatedly telling various recruiters my strongest areas, they ended up interviewing me for what they wanted me to do rather than what I was good at. In fact, one of my interviewers literally had to throw out all his prearranged questions and make shit up as he went because my background and experience were so misaligned with what he had been added to my loop to ask me about.
