Others have addressed this in many areas, and I'd just like to add advice on what I suspect is the underlying issue: people skills.
In case your syndrome inhibits social skills, as I suspect it does, here are a few easy tips for successful communication and interaction:
ComplimentsCompliment
Listen
Show interest
It doesn't matter what the situation is;
Date
Random introduction
Interview
Any situation where you're meeting someone new
As you initialize your relationship with any professional (the interviewer in your case), offer compliments and show genuine interest.
Humanity has a way of appreciating kindness and remembering it. If you go out of your way for just one moment, I promise, you'll see the benefit in the result of those next interviews.
Point out an achievement of the company. "I remember seeing an article on your site about this recent successful product. That was neat." (ComplimentsCompliment)
"We're you involved with that?" (Show interest)
Whatever the response may be, make it clear that you're listening, and then prove it. "That's an incredible achievement. If we end up working together, you'll have to tell me more about it" (ComplimentsCompliment. Listen. Show interest)
Now get down to business.
I promise you, whether you love people or could care less about them, if you can focus on these points of communication and general kindness you'll see results. You'll get that job. You'll impress that girl. You'll make those friends.
Technical skill is not enough. You must practice people skills. Programmers are people too.
Good luck!
