I applied through a recruiter. The process took 2 months. I interviewed at Davis Instruments (California) (Hayward, CA) in Sept 2017
Interview
There were three steps within 2 months: a phone screening with a recruiter, a phone interview with an engineering manager and a face-to-face interview with an engineering team, including test coding tasks and main working concepts discussion.
