It was a rather standard interview process with online application then online tests and then video interview but the role filled before there was an opportunity to attend an Assessment Centre.
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.
