They first contacted me via email, and then called me. The call was a phone interview that I was not prepared for. The interview itself was nice, and similar to the phone interview. However, they did interview me for a position they did not actually have (it was the difference between full and part time!). After I rejected the part time position they were offering, they counter offered with a full time position. I was a bit baffled why they would offer the full time position, say they didn't have one, and then offer it again.

I met with one person. Very comfortable and easy setting. We met over coffee and later I had a phone interview with another hiring manager and it was very comfortable as well
