First, a lengthy application comprising of about 12 questions, asking for 300 words. Advice: give yourself a huge amount of time to complete this. I conducted a lot of research into the company and specifically Jon Steel. On YouTube there are videos of seminars he has conducted which give insight into what he is looking for - and seeing if his ideas fit with yours.
The second part of the application process was an online video assessment where you had to answer the following question: 'If you could change one point in history, whether about yourself or in general, what would it be'.
These questions are likely to change from year to year, but hopefully this will provide you with an idea of what it could potentially be.
