I am still struggling with maths and calculations on the fly during a case. I don't know if it's due to nervousness or fear of judgment by the interviewer. Any idea on how to improve/work on that?

Hi,
In interviews the aspect which causes more errors is pressure: start to solve calculations with strict time constraint. For longer formulas always share the calculation structure with interviewer before starting to write down the numbers: this helps to take time, to reduce the pressure and gives you the opportunity to receive a first feedback by the interviewer avoiding wrong calculations.
I recommend practicing with:

Hi there,
Q: I am still struggling with maths and calculations on the fly during a case. Any idea on how to improve/work on that?
It is difficult to answer without knowing what is the issue (eg struggling with formulas or with the math itself).
You can find below some general tips.

I would also recommend to practice math under pressure - not just math. Many candidates are totally fine doing 67% of 67 in normal conditions, but freeze if asked this suddenly in a case interview.
In order to do so, try always to use a timer with a time constraint when you practice math – this will create pressure and help to replicate the actual conditions of the interview.
Hope this helps,

Hi there,
there can be various root causes for poor case maths..
How you should approach fixing this, really depends on where your exact problem lies.
Would need to understand a bit further your specific situation to advise on the best way to tackle this. Feel free to reach out via DM to discuss.
Hope this helps.

Hi there!
It mostly has to do with confidence.
Confidence you build by seeing that you have successfully handled similar situations in the past.
Which comes down to two things:
Last but not least, it always get better with time. Across all the candidates I've worked with, I've never seen a person not improve as long as they were committed on getting better at math related questions.
Best,
Cristian

1. Become really good at doing it on your own.
2. Significant exposure to an interviewer while doing maths, until it becomes second nature. You may need to add some stress elements to it (e.g. sometimes have an interviewer you don't know).
Hi,
This is also an area I struggled with in the past, given I studied an arts/humanities degree.

All the best!
Hello,
I fully agree with Andi’s feedback here. Figure out the root cause first – what is it exactly that you find particularly challenging with case math? What specifically makes you nervous? If you let us know, we can suggest more specific advice to tackle this.
I love the math-drills and rocketblocks websites.
Hello!
After +5 years of candidate coaching and university teaching, and after having seen hundreds of cases, I realized that the economic-related knowledge needed to master case interviews is not much, and not complex. However, you need to know where to focus! Hence, I created the guide that I wish I could have had, summarizing the most important economic and financial concepts needed to solve consulting cases, combining key concepts theorical reviews and a hands-on methodology with examples and ad-hoc practice cases.
It focuses on 4 core topics, divided in chapters (each of them ranked in scale of importance, to help you maximize your time in short preparations):
· Economic concepts: Profitability equation, Break even, Valuation methods (economic, market and asset), Payback period, NPV and IRR, + 3 practice cases to put it all together in a practical way.
· Financial concepts: Balance sheet, Income statement/P&L and Performance ratios (based on sales and based on investment), +1 practice case
· Market structure & pricing: Market types, Perfect competition markets (demand and supply), Willingness to pay, Pricing approaches, Market segmentation and Price elasticity of demand, +1 practice case
· Marketing and Customer Acquisition: Sales funnel, Key marketing metrics (CAC and CLV) and Churn, +1 practice case
Feel free to PM me for disccount codes for the guide, and I hope it helps you rock your interviews!
