I applied through an employee referral. The process took 2 months. I interviewed at CBRE (Los Angeles, CA) in May 2012
Interview
First, there is a phone screening with the national HR department. Then another interview with the specific location office manager. Within a week after that, there is an online skill test that lasts 8 hours. Lastly, the team(s) you will be working with will interview you. All in all, it takes roughly 2 months to finalize the process.
