I went to the Aerotek branch located in San Jose.
The staff there are not professional at all. They'll have you waiting for a long time if you go in for an interview.
If you want to work as a recruiter, they expect you to know every single detail of how the company is organized and operates before becoming an employee. Through past work experiences, your knowledge of a company you work for grows continuosly and is not learned in just one day.
Look for a work place where people have some class and respect for you. Forget Aerotek.
