Calculation in CHF instead of €

Hey all, I have a quick question. In part 3 of this case, we derive the total revenue in the winter season 2024, but in the bar chart, revenues are given in million CHF, and we only have the prices of annual/day passes in Euros. So, shouldn't we at the end, give some kind of estimation/calculation of how much the revenue was in CHF?

That is a fantastic point, and it shows you are paying close attention to detail—a critical trait. It’s easy to get stuck on these specific unit conversions, but here is the quick insider reality on how these specific tests (or live case interviews) are graded.

In a timed, structured case environment, especially one delivered via a platform or standardized test, the primary focus is evaluating your ability to set up the revenue formula and correctly identify the core drivers (volumes, price points, seasonality). If the necessary conversion rate (CHF to €) is not explicitly provided in the exhibits or data tab, you are not expected to Google it, estimate it, or calculate it.

The strategic move here is to state your assumption clearly and move on. You calculate the revenue using the given inputs (€), and then you present the final number while verbally or in writing clarifying, "We calculated the total annual revenue to be X million, based on the input currency (€), assuming a 1:1 parity with CHF for simplicity, since the conversion rate was not provided." Your grade relies on demonstrating logical structure, not on perfect real-world FX conversion. Getting stuck on finding external data is often seen as a failure of time management and case structuring.

Focus your energy on ensuring your methodology for deriving X is flawless. That is what the consulting firms are truly assessing.

Hope it helps!

Luca, it's great that you noticed this. It shows attention to detail. 

But in a real life case scenario, don't stress too much about it - just ask the interviewer. The important thing is to signal to them that you're aware of this and that you're looking to align with them on the best path forward.

Best,
Cristian
