Endava Java Developer interview questions

I applied for a Java developer vacancy at Endava Romania. I had an interview with HR. They told me that the customer was quite slow and asked if I was ready to wait for a long time for my candidacy and if this vacancy was a priority for me. I replied that I was ready to wait for any answer and the vacancy was a priority for me, in case of another job offer from companies I would inform immediately and would be ready to postpone accepting such job offers. Unfortunately, more than 3 months have passed and no one has contacted me. I was very disappointed, because I spent about an hour of my time on the interview, prepared and learned a lot of information about the company, agreed to the terms of the long wait and put Endava as a priority as I was asked. I hoped that in return it would not be difficult to give at least an automatic refusal, but this was disrespect for the candidate.
