I applied online. The process took 3 months. I interviewed at Rolls-Royce in Dec 2021
Interview
There are three processes, first one would be around 40mins general questions. Second would be a 10mins technical presentation + 15mins QnA, you can pick whatever topic you what to present. Then final one would be a commercial awareness style problem, you will get 30 mins to read the scenario and then answer some questions that were given by the interviewer.
