Pre-screened on phone by company's recruiter. Two phone interviews. Full day on-site interview with 7 different groups of people. All the people I met and talked with were sharp and asked great questions. The process was lengthy but thorough. One downside was that they did not leave much time for me to ask my questions. Typically I was asking them my question(s) as they were walking out the door to let the next group of interviewers in. So I was getting one or two word answers. Great people and very passionate about the company and the product. The office space is completely packed wall-to-wall and people working elbow-to-elbow, and the parking lot was almost overflowing. I'm glad I showed up early so I could make the long walk from the far outer edge of the lot to the front entry. It was obvious the company is growing like crazy.
