“They are not”: “they're not” versus “they aren't”
I noticed that you aren't in and you're not in are two ways to shorten you are not in.
Are they always interchangeable? Are there situations where you would choose one over the other?

Both mean the same thing. However using you're not seems to me to place more emphasis on the negation in speech because of the solitary not.
Another reason to use you're not would be that the listener would less likely mistake aren't for are in a noisy place for example.
