Mobile Product Marketing Question:

This is a common variation of the strategy question. Case study questions can be tricky. To prepare, research the market that your target company is in, as well as adjacent markets and competitors. Review recent tech business stories and analysis to understand current business strategies in play and what issues tech leaders are grappling with. If you are caught off-guard, you will at least have some analogs you can draw upon.
Like the product design questions, start your answer with stating your assumptions about the current business strategy and goals of the company in question. Common case study questions involve new market entry-Michael Porter's Five Forces framework can be a good starting point.
Discuss how the new market or segment fits with the company's core business and complementary business opportunities. Understanding the company's underlying value proposition can help put a seemingly unrelated business opportunity into context.
