The interview was in the Howden Building in centre London. It was an assessment centre that was from 8:30am to 13:30pm. It consisted of a networking session that was around 1hr. The scenario - based assessment which they said it's being done for the first time, was a bit unprofessional for a big company. Then we had 2 interviews, one informal with a team member and one more formal which was the usual HR questions.
