I applied online. I interviewed at Clean Harbors (Detroit, MI) in Mar 2016
Interview
Phone interview was short and sweet! Not as much information was given as I would have liked about the specific details of job. They asked questions about how I handled specific tasks at my current job and how I would handle them at the possible new job. Overall interviewer was pleasant and pretty knowledgeable about the company and job.
