A couple calls with recruiters and an engineer who described what it was like working there and encouraging me to interview. It sounded like they were building an analytics tool in that gathered data to sell to big pharma. No one I talked to there was able to explain to me what they were really trying to do, except somehow they were going to cure cancer with big-data-style analytics.
Interview process was abysmal. The first interviewer was arrogant, made me sit quietly for several minutes during the interview while he glossed over my resume, and generally acted like he didn't care to be there. The other three interviewers were more or less the same, very unstructured, a little high on the company mission (though couldn't articulate it), and antagonistic towards my questions and answers. I wouldn't want my worst enemy to work with any of them. I lost interest almost immediately and should have left early. Automated rejection email afterwards. If this is how they plan on tackling cancer, then I want no part in it.
I had an online assessment first after applying, and after I passed it there was a pair programming session with one of their engineers. The online assessment was more difficult, the pair programming was more practical.
Very long and weird process, you do all the interviews together and then you get the results at the end. You might not get hired because of the feedback of any interview but you still do all of them and I find that such a waste of time.
