Interviewers may ask this question to gauge your ability to evaluate a product as both a designer and a customer. This technique may entail seeing the thing from several angles. To respond, draft a story about how your design background affects your buying habits.  "A team member approached me six months ago after seeing an issue with our new stapler design." I also researched product reviews and business remarks for each model. I went to the home improvement store after narrowing it down to three models.  While there, I applied the same concepts that I use in the design studio to judge the quality of a product, such as solid construction, dependability, and practicality."
