HubSpot Premier Client Manager interview questions

Several rounds of interview culminating in a Case Study role play. I received positive feedback from friendly and bright staff. They have a strong corporate culture that aligns with my values. I had nothing but good things to say all along the process. Except after meeting with 10 different people, devoting hours to case study prep and hearing nothing but positive feedback, I was surprised to receive a canned email saying they were no longer considering me for the role. It was impersonal and really tainted my overall experience.
