Favorite Product Critique

Part of the Product Management Roadmap

In short

"What's your favourite product?" is a trap if you just gush. They want proof you can love something and still see exactly where it falls short.

A prompt asking about your favorite product and what you'd improve — testing genuine product taste and whether you can think critically about something you love.

Think of it like this

Your favourite sneakers

You love your sneakers: light, comfortable, go with everything. But the laces come undone every hour. A real fan can say both, and suggest flatter laces. Love plus honest critique is what interviewers want.

1/5Pick something you truly use, not what sounds impressive. A metro card app can beat a famous AI tool.

The big ideas

What you need to know

Genuine pick

Interviewers can tell when you've barely used something. Choose what you know deeply.

Specific reasons

"It's easy to use" is weak. "Reorder is one tap from the home screen" is strong.

Link to the business

Explain how a design choice helps the company too, like retention or revenue.

Balanced view

Praise and critique together show taste and judgment.

Save yourself the pain

Common mistakes
