By second-round of a senior interview, you'll often be asked: "What would you do in your first 90 days?" Candidates who improvise on this question get filtered. Candidates who walk in with a credible plan move forward.
The structure that works:
Days 0–30: Listen and learn. Write 3–4 specific things you'd want to do in the first month. Examples: 1:1s with the team to understand current state and pain points. Audit the existing systems/processes you'd inherit. Review the last 6 months of customer feedback / sales data / team retention data. Set up a meeting cadence with adjacent leaders.
Days 30–60: Diagnose and pilot. What hypothesis would you test? Which 1–2 changes would you start in this window, small enough to run safely, big enough to learn. Examples: a pilot program with one segment. A pricing experiment. A team reorganization in one pod.
Days 60–90: Commit and scale. What decisions would you make based on what you learned? What would you stop doing, double down on, or build new? This is where you show strategic judgment.
Key: the plan signals process, not omniscience. Hiring managers want to see you'd ask questions before changing things.
