KnowBe4 Sales Representative interview questions

It took about a month to have a final interview after the initial call with the recruiter. She was extremely friendly and helpful in answering all my questions. I was not contacted for two weeks and finally reached out to be told that the position wasn't hiring but that there was a different department hiring. The hiring manager was a little cold but seemed like a decent interview overall. I was told I would hear back with a decision within the week. I was Ghosted. Very disappointed and highly unprofessional. I was excited about the opportunity and invested a reasonable amount of time preparing.
