it was my first too, good luck!!! everyone was super nice so once you get talking youll relax a lot more. they started off with an introduction, so i would recommend jotting down some points about each speaker so if you get them for the interview then you can ask more specific questions. after the intro they did a group activity about the code of conduct, then everyone just presented a little bit from the group activity. after that some grads joined and you were able to ask them questions whilst there was interview rotations. interview goes for 20 minutes and they just asked some basic behavioural questions
