Confluent Sales Development Representative interview questions

Had a phone screen with the recruiter and then one with the hiring manager. What I didn't like about the process was the lack of transparency. I found out one of my former colleagues worked there and was wondering how the process was coming along. It turns out that I didn't move forward, but the hiring nor the recruiter bothered to send me an email letting me know.

The overall interview process took just under a month. I was first approached by an HR who was very friendly and asked relevant questions. I was immediately given the second phone screen by Hiring manager. The hiring manager also took a 30 minute long interview. This interview involved a mock cold-call. The interview seemed to have gone well. But I didn’t receive any communication for 1+ week. Then I was called for on-site interview where I was interviewed by 4 different people. I was expecting an offer since this round went very well. However after 1+ week of no communication, I was called in again for another round. This round was shadowing the team in the office for 4+ hours. Everyone was really nice through every process. But again I didn’t receive any communication for 1+ week. And then I got an email saying I was selected. Overall the interview process seemed to have stretched out over a month when the whole process could have been done in 1 week. Very slow hiring process
