You are asked to improve a car garage by adding exactly two new features. Choose the two, and explain why they beat the other options you considered. ```hint Walk the visit end to end Trace a driver's journey from first noticing something wrong with the car to driving away afterward. Find the step with the most anxiety or wasted time before you propose anything. ``` ### Clarifying Questions - By "car garage", do you mean a repair and service shop, or the garage where a car is parked at home? - Is this one independent garage or a chain, and can the features be physical changes, digital tools or either? - What should the features achieve: more customers, more revenue per visit, faster turnaround or higher customer satisfaction? - Should the features serve car owners, the garage's own staff, or both? ### What a Strong Answer Covers - Settling what kind of garage it is and what the features should achieve before proposing any - A chosen customer segment and a journey map with concrete pain points at each step - A wider list of candidate features, narrowed to exactly two with explicit criteria - How each chosen feature works for both the customer and the mechanics, and what it costs the garage - Metrics tied to the goal, with guardrails such as rework rate and staff time ### Follow-up Questions - If the garage owner worries that showing customers evidence will lower approval of recommended work, how would you respond? - How would your two features change for drivers whose car has broken down and cannot be driven? - How would you test whether the features worked at a single garage, where a clean A/B test is hard to run?

You are asked to improve a car garage by adding exactly two new features. Choose the two, and explain why they beat the other options you considered.

Clarifying Questions Guidance

  • By "car garage", do you mean a repair and service shop, or the garage where a car is parked at home?
  • Is this one independent garage or a chain, and can the features be physical changes, digital tools or either?
  • What should the features achieve: more customers, more revenue per visit, faster turnaround or higher customer satisfaction?
  • Should the features serve car owners, the garage's own staff, or both?

What a Strong Answer Covers Guidance

  • Settling what kind of garage it is and what the features should achieve before proposing any
  • A chosen customer segment and a journey map with concrete pain points at each step
  • A wider list of candidate features, narrowed to exactly two with explicit criteria
  • How each chosen feature works for both the customer and the mechanics, and what it costs the garage
  • Metrics tied to the goal, with guardrails such as rework rate and staff time

Follow-up Questions Guidance

  • If the garage owner worries that showing customers evidence will lower approval of recommended work, how would you respond?
  • How would your two features change for drivers whose car has broken down and cannot be driven?
  • How would you test whether the features worked at a single garage, where a clean A/B test is hard to run?
