I applied online. The process took 4 weeks. I interviewed at More2 (Southwark, England) in July 2016
Interview
The day consisted of key tasks: these were tests that were on numerical reasoning, estimation, clerical checking, etc. Interview would be 2-to-1 or maybe 1-to-1, and a presentation on data that is given to you 30 minutes in advance for you to analyse and then to present. Overall a nice 6 hour assessment centre, and meeting nice people.
