I read it as "I'm trying to make sure I don't hire someone who isn't willing to work with me, and the system allows me to do that." I can't speak for anyone but myself obviously, but I think I interview at Uber a similar rate to your average Google engineer (2-3 times a week), and our interviewing process is pretty similar to what's laid out here. In cases where the interviewer is hiring for their own team, I feel like it's reasonable to assume that the interviewer is trying to hire people they want to work with. Acting in their own self interests, as it were. In some cases that may mean "I want to make sure you are someone I'm able to collaborate with." In some cases that may be "LeetCoding like hell". Regardless, if that's what the interviewer is looking for, the candidate gets a really important insight in to the team they'd be working for and not necessarily indicative of some larger corporate conspiracy.
