    I have been working at Clean Harbors


    Flexible hours. Trusted to give compliance information to client. This includes epa and osha training. Opportunity for extra training and building of skills.


    Currently, the company has frozen raises. This is not the first time this has happened since I have been here in the last 4 years.

    Advice to ManagementAdvice

    Build in more opportunities for advancement within position. This includes taking competency tests to gain more money, training etc. Open raises for good employees.

    Application Details

    I applied through a recruiter. The process took 4 weeksinterviewed at Clean Harbors in April 2014.

    Interview Details

    Applied through Aerotek. Took about three weeks for Aerotek to call and schedule an interview. Two interviews about a week apart. First was with a coordinator (not directly above me) and second was with Tech Ops Manager. He was out of town for first interview. Lots of paperwork involved. I had to buy a copy of my driving record ($12). Took about 4 weeks total. Intensive physical and 3 drug tests (Hair follicle and 2 urine).

    Interview Questions
    • No difficult questions. There is a 10-15 questionnaire about basic things (willing to work overtime, travel acceptable, etc). Very relaxed interview environment.   Answer Question
