I was initially called late June of 2011 for an app I had submitted late May. I was informed that I would be contacted sometime in August with further instructions. I received a call mid August letting me know I had been selected to be interviewed for the position contingent on a drug screening, physical, and testing. I had to first do a 50 question test which involved me being in Riverside at the call center at 8AM. The test lasted about 90 minutes.
A week later I was called and told I had passed the test. I was then asked to go back and interview for the position 9 days later. I completed the interview and was called a week after that and told I had to take a physical and drug screening. I was scheduled to do this in a week.
