Extremely well planned interview process, with sufficient breaks and positive structure. The day included a personal interview, which consisted of two presentations. One about Rolls-Royce PLC and one about an turbofan engine. A group exercise to demonstrate team working and leadership abilites. This was assessed my a minimum of 8 assessors. A numerical test, which was more of a data analysis test - not many people finished but we gathered it was marked on progress. A 1 on 1 interview about yourself, why you have applied, what makes you more employable then the rest of the applicants and so on.
