I applied as an intern, where I only needed to submit a resume, transcript, and cover letter. If your application is selected for a position, you are then subject to a background investigation that involves a background investigator visiting your friends, family, neighbors and yourself, a polygraph, and drug testing. If you do well as an intern, you are non-competitively converted to a regular employee.

Slow, easy. Phone interview only, with a panel of 5 members. Overall, you submit your application, wait forever to hear back, and then a simple phone interview that really doesn't weed out too many people unless they're incompetent.
