OPTiMO IT Developer I interview questions

After one quick phone interview, I was "Hired", and given quite a list of paperwork to complete -- including fingerprints and drug screens -- each of which required my own money for postage. But after several months of waiting, the actual job never became available. This happened a little over a year ago, but guess who contacted me AGAIN.. for the same job with the same client. They were never able to explain what went wrong a year ago, nor why I should trust them by accepting another offer of employment. Stay Away!
