I applied online. The process took 4 weeks. I interviewed at Certified Laboratories (Buena Park, CA) in Mar 2018
Interview
Received a phone call from their recruiting team and briefly talked about the position and the company. I was scheduled for an interview. A week later, was called for a 2nd interview with their manager. A couple days later, was called again for a 3rd interview with the team and take a skills test. Overall the interview went well.
