The way I see it there's two possibilities here, and really these are possibilities on a person by person basis, but we're mostly concerned about the majority of your coworkers/teammates:
1) Your coworkers really are douchebags. In which case, you should find another job. Working with douchebags is never worth it.
2) Your coworkers are OK people (I think it's safe to assume they're not nice), but afflicted with all too common terrible tech industry inter-personal skills. Being more experienced and knowledgeable than you, they recognized your over confidence right away and it turned them off of wanting to be too friendly with you. They assumed you are the douchebag, not entirely wrongly.
The second case might be fixable, if you talk to them honestly. Ask for some advice or help. I wouldn't just come to them teary eyed with your heart on your sleeve, but try being friendly. Most people will take it as a compliment if you ask them for help.
Of course if they react badly to your inquiry, then yeah, they really are awful turds and you should find a new job. This time try to find one with a better environment.
