One day interview process, very straight forward. HR Review came in first for me through call, and once I got the approval went to the office for the technical review.

HR called and invited me for an interview. You get to meet the VP of Tech and any one of their senior devs. I was asked about my experience in general (typical), and then some kind of a technical pop quiz, as well as a quick whiteboard coding test. I had to come back for the "people interview" with the regional manager because he was out, but it was otherwise seamless. Everyone was quite lively and polite, and honestly a pleasure to talk with, from HR (spoke to 2), to my interviewers.
