I recently went through my 3rd round of interviews which lasted 3 hours. The first two has me speaking to a recruiter and a team manager for the CSM role. The 3rd interview had me on a zoom call where I met 2 individuals in TA, a CSM director whom I had a case study to go over, a small presentation with 2 Sr. CSMs, I connected with a Sr Implementation Strategist to discuss cross department work, they it was a Team Manager and Sr. Team Manager for CSM and then concluded with the recruiter that initially reached out. The interview didn't feel like three hours as I kept the conversation flowing but as soon as it concluded I felt it haha.
