My first impression was, "I really want to work here". The office was clean and well-designed and the people seemed to be very happy. The interview was very informal because I came in when a lot of people were on vacation. It was more of a conversation with a Senior Manager than anything structured with HR. I met one other person for a very quick Q&A and then the three of us went to lunch. I received a call a couple weeks later with a job offer and the rest is history.
