Rolls-Royce interview questions

I was given two main interviews. The first was a typical friendly interview with questions such as why I like materials science and why I like Rolls-Royce. The next interview included presenting a 10-minute presentation on a topic of my choice. It was quite relaxed and preparation hadn't taken too long. A strange task followed which included discussing general strategies to develop supply chains in rapidly changing aeroplane fuel markets. This was quite interesting as I hadn't done anything similar before.

The whole process was already been given on their website so that candidates could also prepare well and come with complete preparation so I gave my online assessment and was preparing for face to face interview but couldn’t make it
