Interview Question for Associate at McKinsey & Company:

The way I answered this was to give an overview of the situtation, and then explain what made it challenging (which was a few different things) and then ask the interviewer whether this was a good situtation that seemed worth exploring further. We then drilled into the situation for about 15 minutes. The key to preparing for this question in a McKinsey interview is to have a scenario that you're prepared to really drill into - expect lots of follow up questions (how did you respond/what happened next/what did you learn) - you need to know the detail so choose an example that's fresh.
