Nagarro Architect interview questions

One of the most horrible interviews I had in my 16 years of career. There are kids who take your interview and ask you questions around anything and everything. I was called in on a Wednesday for the interview for their so called urgent position in Austria. Apparently they told me that i was through all rounds and had a final interview with VP. After 3 hours, they said the VP is not available and they will revert back to me. Till date they have not sent even a negative response saying that I was not selected. Very Immature interview process and the HR is very irresponsible towards potential candidates.
