Question about

Is this math common?

Would you be expected to do all the math for this case?  It is not hard, but somewhat time consuming.  I can understand if they expect you to calculate 1 energy source for task 3, but then to do the same calcs for the all the other energy others to me seems like a waste of time. Surely showing you can do the math and have correct reasoning to get one energy source is enough. Is this common with other cases?

 

Also, data sheet A shows 27.1% on the chart, but clearly this does not add up to 100% with the other segments.  In the solution I can see they have used 27.2%  (so does add to 100%  Is this deliberate, are they expecting you to notice this during the interview?

Hi there,

Chances to go through a math problem in a case are usually around 100%.

In case of this example, what the interviewer wants to see are three things:

  1. You are able to establish the calculation logic
  2. You can calculate swiftly and directionally correct for the energy sources
  3. You can interpret the results in the context of the case

What might happen: If you are able to calculate the first energy source swiftly the interviewer will provide you with the answers for the rest - depending on where they put their focus.

It could also be that they have you calculate everything.

Regardless of what they do - focus on your actions and remember, its an assessment and a bit of a game so stick to it.

Cheers,

Florian

Hi there,

I would be happy to share my thoughts on your question:

  • First of all, while the likelihood of being asked quantitative questions in a case interview is close to 100% (in the first round of interviews), I understand your confusion about the amount of calculations required in this particular case study.
  • Moreover, unless you are absolutely sure that it is authentic, I would take any case study with a grain of salt when it comes to its conceptualization, as many are somewhat different from real-life case studies.

If you would like a more detailed discussion on how to best prepare for your upcoming interviews, please don't hesitate to contact me directly.

Best,

Hagen
