Medidata Solutions Senior Software Engineer interview questions

Started with an informal phone interview talking about my previous experience , followed by a take-home technical test, which I submitted and was invited to a face-to-face interview very shortly after. Face-to-face interview was cancelled the day before it was scheduled with no reason given. Very unprofessional.

Put me through 8 separate calls and meetings combined. Positions were supposed to be remote but traveled 2 hours out of my way to meet with team in NYC anyway. Completely aced all phone screens, according to people who conducted them - got every question right during interview process. Invested easily 12 hours into interviewing here. Then I get a call a few days later saying "you were great technically but they didn't like your communication style, felt like they were pulling information out of you." Sure, well that is the idea of an interview, no? Recruiters spam you to multiple teams trying randomly to find a match and expect you to interview with each team separately. Process is insane and a huge waste of candidates' time - feeling really annoyed.
