Update on my last post: the Airbus hold pool swimmers have now been contacted
Captain Span Cam, when I went through it (2014) the day consisted of:
1) Writing two brief essays on arrival (why you want to work for Virgin, etc)
2) Verbal and numerical reasoning tests. The numerical test was pretty much entirely made of data tables that you had to extract answers from ("what percentage of company X revenue was made by the Manchester branch in 2008"). You are given a calculator. Verbal was made of short paragraphs and statements about them ("The study concluded that eating sugar did not increase the risk of heart attacks" True/False/Cannot say)
3) Interview. Standard competency stuff ("Can you give me an example when you showed leadership"), as well as the usual motivation for Virgin, why you leaving your company, etc
No group exercise and no sim.
