Engaging, challenging and informative. A phone interview was scheduled first, was set to be 15min but went nearly 40min. Very engaging first contact. A face 2 face interview was then set up a few days later. This was awesome, I was interviewed by four plus a phone interview onsite. Everyone was professional but very down to earth and like-able which says a lot about the culture if you're tuned into it. Received a letter offer two days later. Accepted :)
