Rolls-Royce interview questions

Phone screening with HR, virtual interview with the director, virtual panel interview with the team, final round in person (excessive if you ask me). They ask you questions about your experience/resume, behavioral, technical scenarios etc. Took 3 months after applying to get the offer. HR is very slow and unhelpful

Turbine based questions: design stategies, pressure maps, components of turbine, types of turbine. Earlier projects,questions based on CV. All the major questions were are on turbines only its diagrams and major components and valves in turbine.
