Phone screen, second round of several short and comfortable interviews with support engineers and managers, final round group interview with learning session and technical skills test. Comfortable and casual interview - very conversational. Come with questions to ask.

Phone interview that mostly consists of getting to know you. First in-person interview consists of going over your resume, learning about your problem solving process with examples, and briefly going over the position. Second in-person interview was approximately a four hour group interview that consisted of a presentation, lunch, and a group problem solving exercise. Seems like a very unique and rewarding company to work for. Unfortunately, they do not have the decency to contact you to let you know that they are proceeding with other candidates or any information about where you stand, despite the fact of spending hours upon hours driving from out of town and at the actual interviews. I would have loved to get some sort of feedback in relation to where I stood and how I could improve because the interview process was a major learning experience.
