I had the opposite experience. I don't have Asperger's or ADD, but I'm shy and struggle with eye contact and small talk. I interviewed at about ten startups, and despite doing well on the technical questions, I got rejected every time. I began to suspect it was because of "culture fit" -- will this 35 year old introvert fit in at our frat house/office?
I was getting pretty depressed after all that rejection, but I got a random call from a recruiter at a big-N company, and figured why not give it a shot. The interview ended up being more professional, and at the same time the interviewers seemed friendlier and less antagonistic. And I ended up getting an offer.
In any case, I'm mentioning this because I went in expecting what you described -- that startups would be easier for me, as a socially-awkward person -- but that's not always the case.
