I saw a Bain case on youtube (couldn't workout if it was an MBA hire or not) but the interviewer asked the candidate to draw an occupany graph.
What other types shall we learn and where can we learn them?
By the way: An "occupancy graph" is not a defined type of graph, but rather a chart (could be a line) that plots occupancy (of whatever, a hotel maybe) against some other variable.
The challenge is to pick a graph that makes sense for the question/data at hand. So for what I do use stacked bars vs. clustered bars? When do I scale to 100% and when do I use absolute numbers? When does a waterfall chart make sense?
At the consultancy I started we had a training which was called "from data to chart" - very useful.
Generally things are kept relatively straightforward: I'd say just ensure you're familiar with bar charts (stacked and clustered, 100% and not), line charts and scatter charts. Bain has an aversion to pie charts, so I'd avoid those.
The interview is more about fundamentals than specific knowledge (obviously slightly different for experienced hires/ experts), so you shouldn't usually have to worry about hugely complex advanced business or statistical concepts.
Any consultancy has an aversion to pie charts. We joked that it was a fireable offense at BCG :-D
Hi,
Here are some sources to learn from (prioritized):
Good luck!
