Rev.io interview questions

First round was on the phone, Second round in person Zoom call with Director Sales, third round in person interview with VP Sales, he was still unsure with me and I did a fourth round that ultimately landed me the job. They asked pretty basic questions and just really want to get to know you

With 6 round of interviews, 5 of them being with different leaders of the business, I found this to be a very tedious interview process as it was just an HR role - Individual contributor. Felt as though I was being screened for a CEO role. Worst part of the process is that after the final interview (the 6th interview), given so much of my time already. I received a generic rejection email immediately after my final interview. Additionally, there was a lot of negative feedback about the prior 4 HR representatives from the CFO throughout the interview process, in which I found to be very unprofessional. Overal, very negative interview experience.
