"Manager asks for help to improve margins. How would you make a recommendation?" This is a mini, no-numbers case question. It helps to have gone through a case interview. Be structured and answer the right question (i.e., improve margin means don't focus recommendation on sales growth/increasing volume ... unless that affects your margin through scale). On structure, think in tree charts - i.e., price and unit cost. Dive a level deeper into each without jumping around too much. Give examples but structure your answer. "Tell me something that surprised you about the firm outside of anything mentioned in the pre-night presentation." This tests your research on the company. The firm self-describes itself as the 'business behind healthcare'...not very self-explanatory meaning you have to do some work upfront and have an opportunity to distinguish yourself. The question was harder because the pre-night is informative in helping to understand pharma and medical distribution/wholesaling. No one expects you to know every business unit or service, but you should understand the business model for any firm you're interviewing.
