Nutec interview questions

They found me. They contacted me via Linkin. Recruiter contacted via a email. To set up a phone interview. After phone interview. Week later. Recruiter again emails to set up a one on one interview. Once arriving at the plant. It was not a one on one. I interviewed with 3 people. Very intense interview. They didn't allow each other to finish a question. Let alone me to answer. Very confusing when leaving. A few days later. Recruiter sends a request for urine drug test. And background. It wasn't. I arrived to take test. And it was a hair follicle drug test. Doesnt matter. Passed it. But they are suppose to inform you, of which one. Before you go. Its the law. A few days later. Another email. Requesting me to come to plant. Arrived at plant. They took my measurements for uniforms. Started work 3 days later.
