Interviewed Jan 2008 in San Francisco, CA (took 3 days)

I initially applied to the job through my Universities jobs website. I submitted my resume and was contacted for an on campus interview. I wasn't able to make the on campus interview so they allowed me to do a phone interview. A few months went by before they were able to conduct the phone interview, they let me know I had fallen through the cracks. The phone interview was 30 minutes long and was more of a "coffee talk" type interview. A few weeks later I had a 1 hour long phone interview which tested my ability to think on my feet. Following that I was invited to an on site interview and the company flew me to the interview site, put me in a hotel, and paid for all of my expenses.
