The recruiting staff is professional, friendly, and communicative (which is refreshing). They were very on top of the process, scheduling of phone calls and interviews, and made the process pretty straightforward.
I had an initial phone call with the recruiter, a second call with the hiring manager, and an in-person interview with ten (ten!) people that was about five hours long.
The interview sessions were 1-hour blocks with different groups of people, starting with the CEO/Founder one-on-one. He was friendly and easy to talk to. The other sessions were with groups organized by roles with the very last group being three people that the role would work closely with.
All the people I interviewed with were friendly and asked great questions. I was surprised, however, for a company who openly values culture-fit so highly (and which I think I'm a shoe-in for) they didn't ask me a single question about myself that wasn't related to the specific job role or the case study they had asked me to consider. Not one, other than some brief banter about football. The final three-person session was by far the most difficult, and all of the above applied to it as well. The beginning of that seemed a little off-putting, and after about 30sec I figured this had to be intentional (they were totally playing it deadpan) to see how I'd react, I think. There's no way all three of them were so not-thrilled to be there–even on a Friday afternoon. I doubt they saved their only three grumpy employees for last. I think the mood lifted a little though, and it was generally pretty pleasant.
They gift you some product when you come in, which is nice, but honestly a little awkward if you're not eventually hired.
Generally it was a solid interview, but it is really strange how all-business it was. It was pleasant, but very antiseptic. I had an interview at a really traditional, stuffy, giant corporation that was more interested in who I was as a person than they were.
