One of the last applications I made for a job had two interviews and then they asked for a third. I told them I was no longer interested. If they can't figure out what kind of a person I am after two interviews, then they are the ones with a problem.
I know a young lady that is trying to get on with a wireless phone company. She's been going through the application process for over six weeks, has sat through four interviews, and still doesn't know if she has the job. I'm assuming she's applied for a customer service position and they are seriously testing her patience quotient.
