AstraZeneca Associate Director - IT interview questions

30 mins screening call with a recruiter, scheduled a 30 min call with a Director. On joining the interview, the Director told me he had an urgent call in 15 minutes, but we would continue the interview on another day. Scheduled the follow-up interview that lasted another 15 minutes. The Director told me he enjoyed the interview and I had to expect to be contacted by the recruiter to schedule the last interview with the other team members. 6 days later I received an automatic e-mail stating they will not move my application forward, but I could ask for detailed feedback. When I asked for feedback, they ghosted me. I don't understand what's the purpose in lying and ghosting. This shows zero respect for candidates.
