Medidata Solutions Analyst interview questions

I applied and heard nothing for over a month, and then the interview process moved very quickly. I interviewed with various HR employees, and then with most of the team I would work with. The interviews were not very structured, and the recruiting process was unprofessional (typos and delays in communications). When I showed up to the interview, I waited for 10 extra minutes because the recruiter did not inform my interviewer I was there. I invested a lot of time into this process, interviewed with 7 different people, and was not even notified that I wasn't being considered for candidacy (after I followed up multiple times). When asked for feedback, I received no response - I understand this is not required, but to get so far in the process, and then have no information seemed unprofessional. They seem scattered and unorganized.

First Class HR!Well run process, really nice people, strong culture and focus! Office is cool, with outdoor patio. Lots of fun parties, relatipnships and cross dept collaboration is really important
