Nucor has group interviews which can be a bit intimidating. Depending on who is doing the interviews you can actually feel that you are under the lamps being questioned for crimes. Other times it can seem very relaxed. I actually had to sit through 3 group interviews to get my position, and the first two were far more formal then the last. The problem with having so many people in an interview is that some people interview others really well, while others don't. Be prepared for anything!
