Firstly, you must deliver a prepared 5-minute presentation on why you wish to join Rolls Royce and what you see are the challenges and opportunities for Rolls Royce in the future. You were then asked technical aspects on jet engine aircraft and basic engineering questions ((equations, root cause analysis, etc.) in an hour long assessment. Finally, there is a 30-minute long team exercise to construct a paper airplane, taking into account the costs of materials and the need to deliver a presentation at the end.
