Application process includes cover letter & application form, first round interview and numeracy/excel/finance tests, assessment centre and final round interview.
First round interview lasted around 15 minutes with someone responsible for campus recruiting. Standard interview questions: Why Factset? Why consultancy? What is the most difficult thing you can do in Excel? Do you know the difference between IB and IM?
I was then taken to a small room to complete my tests. I had 90 minutes to complete all three in the order of my choice. The numeracy and excel tests were very straightforward. Finance a bit trickier as I don't have a financial background but with a little revision of definitions you shouldn't struggle.
For the assessment centre I was asked to prepare a "microteach" - a 10 minute lesson on a skill of my choice. I presented to 7 people (2 assessors). There was also a group task where you were given a list of a consultant's activities for the upcoming days, which you had to prioritise. Again this was in front of 2 assessors. Not particularly difficult, just requires some logical reasoning.
