A “pitch me a stock” question is not primarily a test of whether you can predict a share price. Interviewers want to see how you build an investment argument, connect business performance to valuation, acknowledge what could prove you wrong, and explain the idea without burying them in facts. Clarity is the test.
Market questions test similar skills. You should know the major developments affecting equities, interest rates, credit, currencies, and announced transactions, but memorizing headlines is not enough. A strong answer explains why an event matters to companies, investors, or deal activity.
