As somebody with autism, one thing I'd say from my experience (I don't know how many people will agree) is that interviewing has felt like a much more severe stress test of my soft skills than anything I've had to do while actually being employed. While employed, the vast majority of my social interactions are oriented around some technical task that I need to work on with other people, and conveying information effectively so as to bring about the completion of this task. This is precisely the kind of social interaction that I feel most competent in--I feel like I'm pretty good at it, actually! What I struggle with are social interactions that are more open-ended, that are more about emotional connections and getting people to like you, and I feel like interviewing is an interaction of the latter type.
In this respect interviewing is a bit like LeetCode. LeetCode problems and writing code to satisfy business requirements are both "coding" but they're quite different kinds of coding; someone being able to do the former is probably good evidence they can do the latter, but there are also plenty of people who can do the latter without being able to do the former. So it is, in my view, with interviewing vs. interacting with people on the job.
