Your client has just developed an anti-depressant drug and wants to get it to the market. They do not have experience marketing drugs.

What factors would you consider when advising the client to enter the market? What options does your client have?

Have a first round ZS interview you’re preparing for? Use the Market Study framework to help create the basic structure for solving this case, but allow yourself to deviate outside the traditional structure to form a custom framework. Interviewers praise candidates for thinking outside the box in order to solve practical business problems.

There are no math diagrams in this case. The qualitative difficulty is 2 out of 4. You could expect this case to be presented to you in a first round interview at ZS.
