Was sent for interview through a staffing firm who had worked with them before in their main office. Sent me tests to take before I got there and interview was rescheduled day and time a couple of times. Had to take tests again and pass before I would be granted an interview. After successfully completing tests was kept waiting 45 minutes before interviewer would see me. I was the first of the day. She wrote the entire time. She was all business and left interview several times to IM or email somebody. Second person was a lead who interviewed in jeans and sweatshirt. Very nice.
