A very thorough process, really centered around getting to know applicants on an individual basis, analysing how they would best fit in with the team. First 1-1 interview. Numerical and Literacy Reasoning Tests (more difficult than i originally expected - recommend practicing and going over Maths GCSE bitesize) Then Discovery Day, where you interact with other applicants. Split into: Ice Breaker, Customer Service Questions / Scenarios, Research on Octopus (Partnerships, Social Media, etc), Q+A Session, Individual Interview. If successful Final Call - discussing the role in further detail anything that was missed during the Discovery Day.
