I applied through college or university. The process took 4 weeks. I interviewed at RSM
Interview
Two different socials on campus at nice places, then I got an invite to an on campus interview, then one web interview. Took over 2 weeks to hear back after the 2nd interview, even though they said I should hear back in a couple days.
I applied online. The process took 2 weeks. I interviewed at RSM (Milton Keynes, England) in Jun 2016
Interview
A written, maths tests and introductory test to IA in the office. Then had 2 interviews, one with HR and one with the Senior Management. Then we met some of the team to get an understanding from their perspective of what it is like to work at the company. Honest answers and a very friendly team which put you at ease during the process.
