Took a 4 hour assetment full of logic based questions, and a small section at the end where they give you a run down on the coding language they use and ask you questions about it. Did well enough to move onto the 4 hour zoom interview day, in which you're given two presentations, do a case study with peers, give a 10 minute presentation solo (cant use presentation software), and then you're put in a 1 on 1 interview where you're asked the usual questions.
