Interview Round: Other

Choose a restaurant you love and walk through how you would make it better. ```hint Find what to protect Before changing anything, say why this place is your favorite and what keeps people coming back. Then walk through a visit step by step and look for the moment that still goes wrong. ``` ### Clarifying Questions - Am I improving it as the owner, with the owner's budget and staff, or as an outside product designer who can propose apps and tools? - Is the goal more revenue, more repeat visits, or a better experience for the diners who already come? - Do improvements have to be digital, or are changes to the space, menu, staffing and operations also in scope? - Should I cover dine-in only, or takeout and delivery as well? ### What a Strong Answer Covers - A chosen restaurant and a clear statement of what makes it good, so improvements preserve it - The restaurant's customers broken into segments, with one chosen for a reason - Pain points found by walking the visit from deciding to go to leaving, prioritized by frequency and severity - A small set of solutions, one prioritized with the restaurant's real constraints (space, kitchen, staff, budget) in mind - Metrics a restaurant can actually track, and risks such as losing its character ### Follow-up Questions - Your fix fills tables faster, but the kitchen falls behind at peak. What do you change? - How would you test the improvement in a single restaurant, where a classic A/B test is not possible? - Regulars say the place feels less personal after your change. How do you weigh that against the business gain?
