In most typical jobs, it's best not to disclose, and I've sometimes had problems when doing so in the past -- but this isn't a universal dogma, and it all depends on context. For example, having nothing to lose, I disclosed during a December interview for a direct support job where my clients are also on the autism spectrum. Well, this time it worked! This is the best job I've had so far. I work quiet night shifts, and my boss is amazed and delighted by my attention to detail.
