The assessment day starts with either an interview or the presentation. I started with the interview. There are two of them each asking a different set of questions. Some tips I can give is make sure that you do a but of research of Vauxhall and you know the history. The interviews also consist of a lot of questions where you have to bring up something that you've done in the past so have a few scenarios prepared for team work, planning etc. The interviews are not one to one there is 3 to 4 interviewers but don't let that scare you. Be confident. The presentation material will be given to y and you have a limited amount of time to prepare. There is not much you can do before hand other than refining your presentation skills. You must give this presentation to a group of important people, undergraduates etc. Around 6-10 people. Once again be confident. Lastly group exercise. I am not able to tell you a lot about this however you must work well together with the team. Make sure that you're not pulling back stand out, but let others contribute too.
