A former supervisor of mine, who I remained friends with, recommended me to them, and them to me. I emailed them my resume. They called me on the phone and had our first interview by conference call. My second interview was in person. I received a call the next day that I was selected for the position. I received an official offer of employment by email a couple days later. My initial impression of them was that my immediate supervisor was a very loving man (I ended up misjudging that), and that the CEO was a little cold, (also misjudged that one). So much for my perception.
