Interview Prompt
An e-commerce product page needs to show product name, category, and average rating. Instead of computing the average on each request, design a denormalized products table that stores the pre-computed average alongside the normalized data.
How This Interview Works
- Read the vague prompt (just like a real interview)
- Ask clarifying questions to the AI interviewer
- Write your data modeling solution with real code execution
- Get instant feedback and a hire/no-hire decision
