I applied online. The process took 6 days. I interviewed at TestBest (Chico, CA) in Nov 2017
Interview
The interview process was onsite with two different individuals. The interviews were very organized with scripted questions but didn't overly depend on their question set. The HR director and project manager were very professional in the way they conducted the interview.
