Three stages, the first two rounds were typical interview formats with general questions about past work history, experience, and personality. 3rd round was a mock sales meeting with two senior team members.

I spoke to a recruiter who kept rescheduling with me. After finally chatting I was told she'd love for me to chat with one of the managers. That took a week to schedule. The interview with the sales manager went fine, it was ok, nothing too extreme on each side. I sent a follow-up message but never heard anything back. At this stage of the interview, the majority of the companies I've met with at least respond one way or the other. The extreme delays and rescheduling and never hearing back made it easy to move onto other companies who showed more enthusiasm in hiring.
