Rolls-Royce interview questions

I was interviewed for UI UX designer position. It look 2 months for them to finish my interview. After my final round was done. For a month I had got no response. After putting mail there wasn't any response. When I tried calling multiple times I was told the hiring is freezed I can look for other opportunities. Time killing, didn't find it professional.

Process was good, HR was very polite and sincere about his work. It was good experience though I didn’t crack it. I think interview was for marine or aircraft industry where you had 0 experience. But RR name and it’s oldest technology made me to attend n experience the interview in RR
