I don't know how long ago that was, but today you can obtain an interim clearance in a day or so and a full one in a few months. The gov't pretty much already knows everything about you, you just need to make sure your answers on the SF-86 match theirs.When I worked at Collins Aerospace, one of the mechanical test guys got a new job at another company.
He needed a Secret Clearance, and he told me that it takes a year to obtain. He had to work in a different area until it was approved
