While the people I met seemed nice enough, everything with the interviews being arranged was incredibly slap-dash.
My first interview was rescheduled (sadly after I had already bought my travel) when HR realised that no one would be there to interview me the day he had arranged. When I did arrive for the rescheduled appointment, they seemed surprised that I was there, and the senior person I was supposed to meet had left for another meeting.
Both interviews were a lot of yes and no answer questions rather than probing for competency.
All in all, it looks like an interesting company, but I wasn't particularly upset when they took a couple of weeks to get back to me to say they went with another candidate- or that they didn't give me specific feedback even though I requested it.
