Not long. From answering the ad you talk to your potential manager and that's it. No reference or background check.
I filled out my application during the xmas holiday. Received a
response in about 2 days thru my e-mail giving me instructions
on how to do my interview on-line myself. No company rep would
be interviewing me. Questions would pop up and I would see myself on the computer and answer the questions. I was hired
the next day and could begin work the week-end coming up
without any training or meeting anyone. Because of my previous
experience that I knew what to do.
