Two phone interviews with corporate level HR and then a 3 hour interview/plant tour. During the in person portion the HR lady told me first thing I was dressed casually (Khakis and polo with proper PPE, same I wore to interview for job I have now) and she was shocked that I did not have a powerpoint presentation. I was not told that I needed one and have never heard of an interviewer asking for one either. Over all the interview was not too bad but it seemed a little weird that there was no technical questions at all for an engineering position. I only rate the experience as negative because the way the HR lady acted when first meeting me really threw me off.
