I applied online. I interviewed at I Drive Safely (Carlsbad, CA) in Sep 2012
Interview
asked some basic interview questions by the founders. Then HR gave me a test with basic reading and math skills which I thought weird and unnecessary. They also talk about your score as if it was SAT exam score.
Very detailed, included a pre interview questionnaire that was several pages long, and then 6 hours of in person interviews. Very thorough, went through every single question. People were nice.
