The Logic Foundation of Problem Solving and Case Interview
One of the key drivers for your success in this type of case interview comes from your mastery of the basics: the core logic foundations of Problem Solving and Case Interview. Practice is good, but only when you have mastered the basics (see our Case Interview Concept).
Here are the ten elements in the core logic foundation of Problem Solving and Case Interview, from the moment the case started to the very end when the solution are presented.
Rephrase & clarify the case context and key questions.
A Cause is not enough, but you have to find a root cause of the problem.
In order for each branch to exist in the issue tree, there HAS to be a chance that the root-cause is in it.
- Test if the root-cause is in there.
- Filtering out branches that are not necessary.
Two main types of benchmarks used are the historical & competitors’ data.
This is where the issue my be so remember to check carefully!
No.8: If the root-cause is NOT in the testing branch or sub-branch, move to a parallel branch or sub-branch on the same level
Don’t waste too much time going deep into every branch.
No.9: Keep doing this until the whole issue tree has been covered or until the interviewer would like you to switch gears
Remember to stick to your issue tree always!
No.10: Lastly, once you have identified one or many root-causes, think of solutions to resolve them!
Knowing how to take actions is one of the best traits for a consultant!
