Docusign Sr. Project Manager interview questions

First round recruiter screen where not much information was provided about the team or company. Just general interview process was loosely explained. Second round was with the hiring manager for 45mins. Interview was nice and the hiring manager explained to be the basics about the position. Recruiter calls to say next round would be a loop and that I would be handed off to someone else for the next bit. In the final loop, I had someone completely else from a different team log on rather than who was listed on the invite and was never informed of it. One week after the loop, I send the recruiter a follow-up email only to get an automated system-generated rejection email 5 mins later. Clearly, the recruiting team could use some training in professionalism and human decency.
