Interview process takes the whole day, technical interview involves knowledge about a jet engine, including physics behind pressure and temperature ie pv=nrt. You are given a piece of a jet engine and have to say what it is and how it could have been made. Also a tip is to get other information thats not just on the rolls royce website about materials and such. Then you have to redo one of the online tests, no real problems. Lunch next where you have the opportunity to talk to the assessors, its a good time to find out more about rolls royce, what its like to be an employee etc. Now the team exercise, you're probably going to have to make a bridge/tower out of paper, cups in a set budget. Make sure you read all the instructions fully and if you can try and be time keeper and voice your opinions and raise questions. For me the last part of the day was the personal interview, make sure you know your presentation off by heart so you're not constantly referring to notes. Be ready to have example's of when you've work in a team, met goals, worked with other people who work differently to you. Throughout the whole day be energetic, talk to everyone, ask questions and look smart for the interview.

2x 15 minute presentation & follow up questions (for up to 1 hour) - one technical, one motivational, and a 30 minute group excerise. Small groups of 8 that were split into two teams. Interviews were conducted as part of the follow up questions on your presentation. Questions were unprepared.
