For example, let's say that the interviewer asks to give an example where the candidate had to work with different groups and deal with challenges as the groups did not agree. What if the candidate never had this specific experience? Let's say the candidate has significant experience and been reasonably successful. At some level, it would be a bit unfair to assume that every candidate had such an experience as it is somewhat too specific and narrow. Can she just say that she never had such an experience? Or the expectation from McKinsey is that the candiate needs to come up with a good response?
