Even if they don't make you anxious (that started to subside after the first hundred times or so) they're still not a good time. I've had senior staff running interviews at big companies do things like harass me over data structure choices, insist that I was lying when I described a textbook algorithm, accuse me of industrial espionage, and all other sorts of absurd or unpleasant things. In some cases even after that I still got an offer, because the interviewers weren't out to give someone a hard time... they were just bad at running interviews. One of my all-time worst interviews involved the design director (?) at a billion-dollar game studio calling me (unscheduled!) at 7am and demanding that I come up with 50 unique uses for a paperclip. Really.
The gap between an average or bad interview and a truly good one is enormous, and the number of well-conducted interviews I've had is incredibly small. I can only imagine how much worse it is for someone with additional obstacles, like how is someone in a wheelchair supposed to stand up and write C++ on a whiteboard for 30 minutes? What does the whiteboard interview look like for a blind woman?
