I applied online. The process took 4 weeks. I interviewed at PwC (London, England) in Nov 2013
Interview
First you go through an online application form. It is fairly straightforward and not much writing is involves. After this stage you are automatically invited (if I remember correctly) to a numerical logical reasoning test, as well as a personality questionnaire. I got invited to a phone interview 2 weeks after completing the questionnaire and tests.
Interview questions [1]
Question 1
Tell me an example when you had to change your approach to a situation.
