I went to a consulting event a few months ago, where the feedback I got was that I needed to speak up more in large groups. Since then I have practiced that every second week in a group of 10 at school, working with the aim of making our study program better. Now I have an interview with that company, and am planning to mention their feedback system when they ask me "why company x?". However, I am afraid they will ask about the feedback I got from the event, and that the effort I have taken have not been enough? Should I?
