I don't know if this works in your area, but try to apply on startup company or small company with small team. Mostly they are more easier to get. Instead of talking about your personality, they're more into your skills and capabilities. Especially if your job requires portfolio (such as design), they would look at it instead paying attention on your gestures.

Try to googling about the good gesture and common interview questions. If you have trouble with eye contact, look at their forehead. Just keep looking at them unless you need to not. For facial expression, I'm only smile if they're smile too. And don't forget to ask them some question about work to show your interest.

Analyze them too. Mostly, if they're abusive in interview session, they will abusive to their coworkers too.
