A Good amount of hours
Area tends to be kinda messy
I applied online. The process took 4+ weeks. I interviewed at Penske (Detroit, MI) in June 2013.
One phone interview and 1 face to face with executive team member. Interview was rather easy. Reviewing glass door is all the prep you need. They never asked about my preparation, competitive insights, etc.
Beware: they make a lot of false promises about pay and training. I never received a full day of training and they withhold all bonuses to date despite promises.
