Difficulty: medium
Interview Round: Other
A small grocery store opened recently in a city. Business is good, and now every aisle is crowded with shoppers. How would you solve the crowding problem?
Walk through how you would find out why the aisles are crowded, which changes you would make first and how you would tell whether they worked.
```hint Find out what kind of crowded it is
Before proposing fixes, ask when the crowding happens, where in the store it is worst and what shoppers are doing while it happens.
```
### Clarifying Questions
- Is the crowding constant through opening hours, or concentrated at certain times, such as after work or on weekends?
- Every aisle is busy, but are some spots worse than others, such as fresh produce, the most popular staples or the area next to the checkout line?
- What does the owner care about most: keeping sales growing, making each visit pleasant, or both? Is moving to a bigger space or opening a second store an option?
- What can the store change: staffing, opening hours, the layout, or adding orders for pickup or delivery?
### What a Strong Answer Covers
- A stated goal that keeps the store's growth while making shopping comfortable, within the constraints of a small store
- A diagnosis of the crowding by time, place and type of shopper, using data a small store can actually collect
- Fixes across several levers, such as spreading visits over the day, shortening time spent in the aisles, improving flow and moving some demand out of the store, prioritized by impact and cost
- Success metrics for congestion and the shopping experience, with sales and basket size as guardrails
- Risks of the changes, such as annoying regular customers or losing impulse purchases
### Follow-up Questions
- The owner cannot afford more staff or a larger space. Which two changes would you make first, and why?
- If the store adds online ordering for pickup, how do you keep staff picking orders from making the aisles even more crowded?
- How would you tell whether a layout change reduced congestion rather than just moving it to another part of the store?
Overview: A product sense question about a small, newly opened city grocery store whose success has left every aisle crowded. It tests whether a candidate diagnoses when and why the congestion happens, proposes practical fixes for a small business, prioritizes them and measures success without hurting sales.
