I applied in-person. The process took 4 days. I interviewed at Crystal Clean, LLC (Elgin, IL)
Interview
Long, four interviews for the same questions. Be prepared to ask a lot of questions. They like you to ask them about the company and specifically about the role, your part in the team, and how you can immediately begin with challenges they're facing.
Interview questions [1]
Question 1
Normal questions you'd expect. Do come in with a lot of your own questions for them.
I received a call from the Supervisor and then went in for an in-person interview with the same Supervisor. The interview was not difficult at all and the questions were average.
