Four one-on-one interviews with upper management with a plant tour and lunch. I was already personally familiar with the interviewers and one of them was using his cell phone throughout the entire interview; very rude but not entirely surprising from the particular individual. Another asked difficult technical questions not at all related to the job just seemingly to set me up for failure. Then to top it off, it took about two weeks longer than promised to receive feedback. Very poor experience from a reputable company for which I had formerly had a good perception.
