Online tests which were finance and competency based. Then invited for an assessment centre where excel skills were tested and there was a presentation of our choice on something interesting or a skill. Then invited for a 1 on 1 interview with some of the managers who ask a series of questions about why you want to join the company etc.

Had a brief phone call with the onsite recruiter, after which I was invited to an assessment centre. Shortly after the Assessment Centre I was invited back for an interview with two managers in the London Office. After finishing the interview I got an offer later that day. Very good process and nice people to interview with. Make sure to prepare the micro teach for the assessment centre, and make sure practice it multiple times before the day, 50% of people in my assessment centre pretty much excluded themselves just because of poor presentations.
