Ritual Partnership Manager interview questions

An initial call with the recruiter followed by a video interview with two managers. I was then invited to an onsite interview, was told it would be with one team member followed by another with a manager. Interview with a team member was more culture fit, easy conversation. Unfortunately what I thought would be just another interview with a manager turned out to be a sales demo with a remote person watching via webcam. Not only was I not informed that this would be happening I was given all of 5 minutes to prepare after being verbally given the target information. How can you expect a candidate to perform properly in an already stressful situation? How do you expect your company to look when your interview process disrespect and distrust? It's a poor hiring technique and sadly does not help you see the real value in a candidate.
