2 rounds of interview 1 lasted 3h30 (expected 1) 1 lasted 1 hr with random members not from team The first round, the manager was going about it asking random questions came 1 hr after 2 other members interviewed me ( the schedule was one hour) then started to be snarky and made comments about concepts being learnt in primary school while stating them incorrectly. Total waste of time in my opinion and very slow/unclear process. They have been interviewing for 6 months for 12 months contract so that should tell you a lot.

only 1 stage and then you get a yes or no to get hired. applied online, interview in person, make sure the consultancy companies don't screw you. get hired directly with the company
