I have Asperger's syndrome as well.
I have never disclosed this during the interview, but if you must, go through autistic job placement services and companies such as hireautism.orgHire Autism
The department of labor can also help you find agencies to place you. More importantly, they have good relationships with the companies, and these companies know what to expect.
There are also hubs like Life in Progress which contain a wealth of resources. Any of these options are good because you are going into a situation where they understand autism and want to hire people with it, and your behaviors will not be misconstrued.
Now. as to why you should not limit yourself to these options.
You need to develop your people skills to maintain a job.
Now, I fully understand how superfluous and needless these social dances are. They have nothing to do with how well you will do on the job. But they are important, nonetheless. Many thing that we do seem unnecessary, rude, quirky and even odd to them.
It is important to learn and develop to at least a rudimentary level, otherwise your life will be needlessly difficult. Unfortunately, things that come easy to the Nuero-typical do not come easy to us.
I have a bookshelf populated with books on closing sales (useful for interviewing) How to Win Friends and Influence People, the Seven habits of highly effective people, as well as Brag: How to Toot Your Own Horn Without Blowing it.
Social skills can be learned. Do not define yourself by your diagnosis. It's hard, DAMN HARD to learn, but it can be done, and I think you should at least put in the effort.
