Quite disorganized one-on-one interview with shuffling me around the office for about 4 hours, I interviewed with the same people about twice. The impression I got from the office was disheartening, the upper management lacked the passion for engineering or projects they were doing. Some even lacked the up-to-date technology knowledge by about 2 years. However, the supervisor of PET lab was passionate and knowledgeable. They didn't ask me anything about technical experience I had, just about recent job experience that was quite irrelevant to the qualifications of the position I applied.
