Poor management - Loader Operator Copart Employee Review

Went for an interview. Did have the paperwork and drug screen swab. Went on break. When returned from break was informed I couldn't be hired. Tested positive for THC. Funny thing about that is I had the same drug screen the day before for another company and passed. They checked it in front of me and everything. I have a commercial driver's license. I don't mess around with any type of drugs. If the test is performed on company and you are present. Wouldn't you think it would be checked right in front of you and not when you leave the room. Sounds kind of fishy to me. The person doing the interviewing acts like he doesn't want to do it that it's wasting his time.
