The right way to read a graph in a case interview and a set of graphics, is not to look for each insight, but to extract the overall message. Most candidates take enormous pride in reading every insight they can find and proudly highlighting them in no particular order - and the waiting for instructions. While there is nothing wrong with this, it is not the way consultants read cases and requires someone, usually the interviewer, to guide the prioritization of the information and generation of the next steps in the case. You can impress the interviewer by weaving together the one most important message, relevant to the case, from all the data.
