There's a good chance they didn't need that information. I met a girl through a support group for adults with autism. She was recently diagnosed as was I, so we were sharing our experiences. Her story had me cracking up! Her evaluator knew she was autistic before the evaluation started. She showed up with tons of legit academic research articles, results from online assessments (including ones where she tried to pass at NT but still popped for autism), and expectations for the process. During the assessment, the evaluator cut it shorter than expected, the implication was that they were 100% convinced she was autistic without needing to go further. At the end, the girl kept asking them for the results, but the evaluator couldn't provide them immediately. Instead, the evaluator kept hinting that she was autistic, but the girl continued to insist on a direct yes/no answer. That story was a riot. We were both laughing our asses off.

The point is that a lot of the information they need isn't details about your history, but instead, how you present. How was your communication, body language, etc. If they didn't ask about it, then it was probably fine. Also, if you're autistic, then you're more than likely not going to pass as NT with an expert on autism evaluations. They do this 5 days a week for years. They know what to look for.
