Final interview is one day interview onsite in the canary wharf from morning 8am to afternoon 3:30pm. 20 candidates in total. It is very competitive but the interviewers are very nice and friendly.

Started first on an online test with generic sjt's and some easy calculations. Then invited to hirevue interview, where they ask a bunch of different questions and you are asked to video record your own answers. 30secs prep, 2 mins answer.
