You'll get a couple minutes with a recruiter. It might be 3 minutes, it might be 10. They might just glance at your resume, give you some advice, and send you on your way, or they might let you talk and explain a lot of things. Bottom line is this - from the moment you travel to WIA, you're "on". Assume that someone is watching you. Every single person you talk to could impact your career. And for the love of all that's Holy, do NOT be that guy on your phone when you're standing in line.
