Let's take one step back, I think it would be important to clarify: Are you having problems to read charts and graphs also outside the business case, in your day to day life?
… I would guess you may struggle to identify what information is relevant for your case, as during the interview, you may be given information out of which a significant part is not relevant (testing how you prioritize, 80/20 approach, able to navigate in complex problems).
If you struggle overall with the graphs and charts, I would recommend any course in the internet that gives tips and tricks. If you struggle only during the case, then I would recommend:
- start practicing cases where are no charts and graphs to identify what process works for you and so being able to transfer that process
- most importantly, when you approach the case and you formulate your early hypothesis, you identify what is information you will need to test it. This should help you to read the charts.
