MongoDB Email Marketing Manager interview questions

The initial call and interviews over the phone were fine. However, before I went to my in person I didn’t receive a line up of who I’d be meeting with to do any prior research, so the amount of people and names were unknown to me before I walked in. Also, I asked for a list of emails for the people I met with after the interview and I didn’t receive them. I then followed up again with the recruiter for that information and got no response. This left me unable to send thank you emails to the team. I felt not answering my email requesting that information was very unprofessional. Lastly I didn’t hear an update for about 2 week after my interview, I had to reach out in between for some sort of clarity.
