I applied through a staffing agency. The process took 2 days. I interviewed at PwC (London, England) in Feb 2014
Interview
I sent my CV to HR who then contacted me to ask me to come in for an interview and psychometric test. Came in, did both and got to speak to other associates to ask about the job and the qualification. Spoke to one of the partners too. Got contacted after to come back for my partner interview which went well. Got offered the job a week later. My advice would be to prepare for potential questions you could be asked, best bet is looking on The Student Room.
First part is the Technical exams (super basic accounting knowledge). If passed, you'll also take Cognitive, Visual and Listening exams. After that, you will proceed to the initial interview and then the final interview.
