I had applied online for months but had no callbacks until I met someone who worked there who referred me. I was then contacted by a recruiter who set up a phone interview with me. She was nice and approachable and gave me her cell number for any questions. I was then contacted by an Analyst at the corp. who interviewed me over the phone. It was dfficult to gauge his responses, and he really seemed disinterested so I didn't think I'd get called in for the in person interview. Thankfully, about a wek later, I did. The headquarters were really impressive and I knew upon walkig in that I'd be lucky to work there. A group of interviewees were picked up in front by some kind of tour guide who took us into another room and described the process, the job and the day we were beginning which would consist of 2 panel interviews and a personality/math test. Both interviews were very informal - why did I want to work there and what could I bring to the position types of questions. Very approachable people. The test was challengin, but not impossible. I left feeling great about the company and 2 days later, got an offer.
