@George It's possible you'll have to talk with a camp on Skype but I think it's more likely you'll get emailed or hear after the fair is over because I know there's gonna be ALOT of Americamp applicants attending the fair. What happens is you'll be able to see the camps online and the camps will be able to see all the applicants online.
You'll be able to see their camp name, the start date of the job, the staff they're looking for etc. And the camps will be able to see your Americamp application (which includes your youtube video and references).
When you get onto the fair, you'll see which camps are online and what they're looking for. You'll have 5 "pitches" and there's a button on each camp's page which says "pitch". A pitch is literally a typed message to them you get a character limit of a few hundred words - so be careful to write the best you can.
So say for example you see a camp online it'll have a picture and when you scroll over it or click (can't quite remember) it gives you an overview like i've written below:
CAMP EXAMPLE
Looking for
Counselor:
Media
Arts
Sports
Support Staff:
Kitchen
Cleaners
Security
When you click to go to the camp's page you'll get a more detailed explanation so it'll say what kind of media, arts, sports they'll want. It should say the location of the camp, the start and end dates of the employment, not sure what else but all the important info. So if you were to click on this "CAMP EXAMPLE" and see this:
MEDIA:
Programmer
Video
Photography
Then you would want to "pitch" to this camp and say that you're a programmer and all that jazz. Then they'll recieve your pitch and may or may not contact you, this could be Skype straight awayish or email you sometime in the near future or Americamp might email you saying you've been "Short listed" or you may not hear back at all - which is why you should try to pitch to as many camps as possible.
Oh and if this helps, I saw at the last virtual fair that 'Camp Canyon' was looking for a "Social media programmer" not sure if they've found anyone yet but check em out when they come online and see. I think you may have a harder time finding camps to pitch you because your field is so specific, so don't worry if you can only find one or two camps you want to pitch to. I had the same problem as I'm doing video production and alot of camps are mainly sporty and active.
Good luck though! If you're still baffled we can Skype or msn or something and I'll try and explain more!
