I get the same problem here with applicants for our webcam houses, we use a 25 question questionaire which helps weed out teh flakes, someone who fills it out fully wil have spent at least 30-45 mins on it and will hopefully show they are somewhat serious. Even so we get a lot of people who then dont call us back , if we do talk to them we normally spend about an hour on the phone with them , then if we scredule a 3 day interview at the house so we get to see them and they get to see us. probally 60 - 70 % of people scedule then dont show up.

of course we are offering them a 6 months contract so we have to check them out thoughrally.
