    Interview Details

    Don't believe the job listing; it's not a good reflection of what they want in an employee. They were completely uninterested in a fresh college grad with a BS in Geology. Mostly they just want people with experience moving hazardous waste, and they seem unwilling to train someone without the necessary skills. Of course, they informed me of this after canceling the first interview the day-of, then rescheduling for a phone interview which they ended up completely forgetting about. I called them and got the phone interview the next day, but overall I felt the hiring manager was disrespectful.
