Hi Mike, I feel for you. From reading your story, I sense that you are very self-aware and that you are a humble person. Great qualities.
Would it be possible to go back to any of the interviewers to get feedback and to tell them if it would have been better for you to tell them about your ASD? IF that would have made a positive difference?
My 26-year-old son has autism, and also an intellectual disability. I write a lot about him (with his permission!). I know that ASD never says anything about your work ethic or abilities.
Very best wishes
