KM.ON interview questions

I have requested an agenda about the meeting 3 times, then they finally bothered to answer. Was on time, and ok. They were not able to answer some of my counter questions about the company. Two reps were present (HR and Sales) No clear job framework was provided. No clear direct reports info was provided. No clear benefits were provided.

Worst experience. After 4 rounds of interviews, they said skill set are not matching. In reality they did not want to give asked salary. Interview process is Simple: First HR discussion, Architect discussion about the project, Tech interview, Coding challenge with average complexity , Product owner and Tech Lead discussion.
