This kind of presupposes that you have suspicions about autism rather than just something in general. If you think you have autism, you're can target that literature anyway regardless of the diagnosis, while if you have no concrete suspicions, you'll be firing blind, and probably miss a lot more than if you could nail it down to one diagnosis.
By the time I got mine, I didn't need the processes, since I'd figured those out by myself, so the diagnosis is just a nice piece of paper pointing to a road I've already walked.
For ADHD though, that story is very different, since step zero there really should be medication,[1][2] and that is locked behind a diagnosis.
Nobody will accommodate me in two years of job searching. They don't deny me outright, they just ghost me if I ask to do a "take home" or any other alternative.
