It's only different in that, unless you're contracting, they're fairly uncommon.

Meetings and code reviews happen every day (or at least a few times a month), so you're well versed in their protocol.

Make yourself well versed in the protocol of interviews and they won't be any more stressful than any other type of meeting.

I find its helpful to think of people in a similar situation: door to door salesmen (possibly they're more disadvantaged, than you will be in an interview, I mean you know you've got the skill set or you wouldn't be there, they might get turned away just for being salesmen). Now a door to door salesman doesn't get terribly nervous selling something at the door of their house. Why? Well they do it hundreds of times a day, and before that the practice their marketing spiel, and techniques for getting the customer on side.

Practice questions, practice those body language techniques, practice telling jokes, and generally getting the interviewer to open up. When you do into do the real thing it won't be a big deal at all because you've practically done hundreds of them.
