I applied through a recruiter. The process took 3 months. I interviewed at Adecco (Mountain View, CA) in Aug 2018
Interview
Single onsite after referral from temp agency representative, performed test drive of analogous vehicle, answered questions while driving with known hazards on route. Swapped with other applicant and documented their answers while riding and made observations of external environment. Performed as I perceived the job would expect me to perform, vigilant, curious, scrutinous while being detailed and positive.
I applied through an employee referral. The process took 3 weeks. I interviewed at Adecco (San Jose, CA) in June 2014
Interview
Three interviews, one phone, one video call, and one in person driving interview.
Call was with Adecco, the other two were for Google, the company using contract employees. Interview with Adecco was easy. At Google they want to know your background, if people can tolerate you, and how you handle stressful situations, etc. They wanted to make sure I was a good driver because this was a professional driving position. Overall it was average/easy.
