I'm not anticipating you'll read this, but for anyone who happens to read this part of the thread, I don't think job fairs are even close to what I described above. They serve similar purposes, but in my case described above, an actual hire will occur or it won't. Job fairs, at least the ones I've been to are more like an advertising kiosk in a mall where no one you're talking to has any authority of any kind let alone deciding whether or not to hire you on the spot :)

Also, at a job fair you have no idea what the day to day life will be in your new position. In my scenario, once you are or aren't hired you will have already lived the life you will be living if you are hired.
