As many of you know, the first question at McK case interview is the following:
What factors will you consider to tackle the problem?
My question is which approach should I use at my interviews:
Approach I: a) branstorm all factors to the level 3-4 and tell all them to the interviewer
b) develop criteria and prioritize
Approach II: a) choose the criteria for prioritization
b) brainstorm Level 1 factors
c) pick up the most important factor based on the criteria and brainstorm ideas to the level 3-4
For me, it seems that Approach II is more rational than Approach I. What should I do?
