It is the standard process as with other major companies- telephone interview, psychometric tests, personality test and then a final Assessment day in London. The process takes up to around 2 to 3 months. I applied in May and went to the assessment center in July. On the assessment day you get 3 tasks. A fact finding and presentation task (mainly to identify whether you can sift through copious amount of data, and be able to pick out important points and present it in a logical and organised manner), then there is a group task and finally a competency interview with one of the Hiring managers.
