HubSpot BDR interview questions

I was referred by a friend who works at HubSpot. The interview process was quite lengthy. It started with a self-recorded questionnaire followed by a phone screening, another 30-minute call with a hiring manager and then three 30-minute interviews with one of them being a mock sales pitch. Two of the three managers I met with seemed as if they could not care less about being there and they were forced at gunpoint. Disinterested, clearly checking their email/phone while I was answering questions. It was a pretty big turn off. I made it to the last round and was not extended an offer. The feedback I received is that my cold call skills could have been better (which was very fair) and that one hiring manager thought I "only wanted to work there because I had friends there." Overall, HubSpot is clearly a great company with a great product. However, I felt as if some of the folks I interviewed with could not care less about me, my experience or bringing me onboard.
