Case Math

Hi there,

This is all founded on good case leadership!

You need to develop your ability to drive the case forward.

To do so, you need to be extremely clear on the objective. Then, at every stage of the case you need to use frameworking to figure out the pathways of where you might go.

If you can determine what you need to calculate and why, then you can setup the general formula to get there and see what variables/data are missing!

This is extremely hard to learn on your own…if you're struggling, consider getting a coach to help you with the case (math) leadership!

Rocketblocks is a good resource for practicing this.

Hello!

If you have the tme and budget for it, I agree that the best approach would be getting a coach, since you can diagnose the prolbema nd then directly target it. 

If you want to do it by yourself, a few things can be 

1. ​Multiplying double digit numbers (you can find videos about this in Youtube, unfortunately we cannot post the link here but they are easy to find)

2. Leveraging math tools (Mimir math for iOS), Math tool on Viktor Cheng website to practice

Hope it helps!

Cheers, 

Clara

Hi there,

Q: I have a final round coming up and I have a hard time with math logic. Any tips on how to improve this quickly?

I would try to clarify first the exact reason of the problem. It could be due to a variety of things:

1. You misunderstand the objective and answer the wrong question
2. You don’t ask the right clarifying questions
3. You freeze and are unable to ask for help from the interviewer when needed
4. You have not done enough math drills, thus you have seen a limited amount of math problems and cannot quickly identify the optimal structure
5. You get confused when you get a large amount of information

Once identified the exact problem, you can drill down on a solution for it. If you want please feel free to message me and I can check if I can direct you to the right resources according to the issue.

Best,

Francesco

Hi there, 

Difficult to give precise suggestions without having done a case with you , but typically candidates that struggle with converting case facts and objective to a mathematical statement do so because : 

(1) They have not understood the problem that is asked to be solved 

(2) Have not understood the client business model 

(3) They have not asked the right clarification questions 

Case math drills practice or coaching session with pointed feedback could help. 

Thanks 

Hi there,

If you want to improve quickly, your best bet is to get a coach.

The problem you describe is very high level and doesn't really get to the bottom of it. It could be related to:

• Objective definition (being clear on what you're actually solving for)
• Data sufficiency (making sense of existing data, finding ‘hidden' information, and knowing when to make estimates)
• Unit tracking (assigning right input units and arranging correctly to get the right output unit)
• Packaging (avoiding overly complex formulas by creating distinct little packages)
• Communication (articulating your approach and aligning with interviewer, which throws off many candidates)

These are just some of the skills you must master and the root cause for your struggles might be one or more of those things (or something else - list is not exhaustive).

Hope this helps. Let me know if you'd like to discuss more.

Best of luck!
