I was invited for an interview at one of the big consultancies and part of the selection process is a group case. Generally, I quite confident in (regular) case interviews and have already received an offer from a smaller firm. However, I am not the most extroverted person and therefore a little worried that this part might become my bottleneck. I would consider myself a good teamworker - I participated at several case competition where I had significant input on the outcome, even in a leadership position - but that was in a cooperative setting and not in fierce competition, where everyone just tries to shine for him/herself.
Do you have any tips for performing well (or at least passing) this stage, assuming that everyone will try to be "the leader"?
