Commercial awareness is obviously a big thing, but that is easy to rectify. Read more, but also try and utilise any contacts you made at the firm. Is there anyone you could message and ask for a coffee to discuss commercial issues, not only so you get the knowledge but also just become used to talking about that stuff, especially with people who are more knowledgeable? I'm guessing it's not stuff you usually talk about outside of the application process and a formal interview. I find that my confidence massively hinges on how knowledgeable I am on whatever is being discussed; perhaps you're the same. In terms of the complex questions, is there any way you could practice these with friends who are in a similar situation?Thanks for the advice! The insight week was with the same firm where I did the vac scheme. I was fast-tracked to the AC due to my strong performance during the insight week. Following the exit interview, I was told that I lacked confidence when presented with complex questions and that my commercial awareness could be stronger. That was the only negative feedback that I received; the remaining feedback from my supervisor and group tasks was was all positive.
