Ping Identity interview questions

This company needs interview training. Loosely defined interview process. Was originally told it was 2-3 interviews but it ended up being 4. My first interview was with the recruiter to go over logistics pay background the usual. Second interview was more high level and conversational with the VP of CS.No structured interview questions or behavioral questions. The call was literally brief intros then I spent the next 45 minutes asking questions. The 3rd round was with a principle csm. This is where things took a turn. He was so rude and condescending. I logged in a minute early. Their camera was initially off and his microphone muted. I introduced myself after sitting there for 30 seconds of radio silence. No response so I figured well maybe he prefers cameras off and doesn't realize he’s muted. So I reintroduced myself and mentioned not sure if you're speaking or not but your microphone is muted in a playful tone. He then turns on the camera looking annoyed and says you didn't hear me because I wasn't speaking and starts rambling about how busy he was. No hello, how are you? He was extremely unprepared. Asked me if the recruiter was joining or if I knew who else was supposed to be interviewing as if I work for the company and would know. Also mentioned he doesn't normally do interviews which I could definitely tell. We started off with me introducing myself and not the other way around. I felt like I was taking the lead in the conversation. No structured interview questions. I could tell he was just winging it. Lots of long pauses as he scanned my resume and looked for bullets to ask me questions on. He really didn't know what's going on with the company. I asked a lot of questions surrounding KPI’s, csm day to day etc. to which he could not give tangible answers for. I asked what are things that would be a cause for concern in terms of account health using their internal crm. He said he didn't have concerns because he’s never had a churn. I didn't buy it so I reframed my question. What are the companies top churn reasons? His response was client expectations with no elaboration…… I think he just threw that out because that makes no sense. That's not a churn reason. Asked about onboarding and he gave me an answer I could tell he made up. Said it was 90 days long then shadowing for a month. That 4 months of training. He also didn't know what KPIs were tracked. My subsequent interview was completely opposite. Learned training is a 6 week period not 3 months as I was told in the prior interview. It was a good interview which I expected to be my last. Towards the end he stated there would be another interview. I reached out to my recruiter for next steps and was ignored. Reached out again for the following week for an update and told me I should know something by the end of the week. After 4 interviews I received a generic rejection email from a no reply inbox with zero feedback.
