Delinea Channel Manager interview questions

Interviewed with the hiring Director and one of the VP of sales. First interview went well but the 2nd one was not so great, mostly was not prepared since I was not given the information that would be discussed. Still was asked to interview with the final another VP, final process and asked what available times I had. Gave availability and did not hear back. A few days later I was told that they were going with another candidate. Very unprofessional, especially given I spent the weekend preparing for the final interview.
