⟩ Tell me did you get an offer to return from your previous summer internship?
If you did get one, that is a positive answer. Explain why you got the offer, and why you’d rather work in Consulting instead.
If not, find a way to logically explain why you did not. Do not go too deeply into negative details surrounding your work performance, unless you have a well-thought out way to explain how this will not happen in your next job.
