DataRobot Associate Applied Data Scientist interview questions

DataRobot forced me through 6 interviews, including a presentation, and then sent me a No-Reply ending my application after scheduling a 7th interview 2 days in the future. They did not contact me about the interview cancelation, but rather sent me a no-reply form email and canceled the Google Calendar invite without contacting me directly. They kept me in the dark during the entire process, and wasted my hours of my time. Their HR team is incredibly unprofessional and non-transparent. I would not recommend interviewing at this firm.
