How do you actually know if your PM interview answers are good? I couldn’t find a good answer so I built something

I’ve been deep in PM interview prep and kept running into the same frustrations.

After answering a practice question, I genuinely had no idea if it was good. I’d finish and think — was that structured enough? Did I go deep enough? Did I make too many assumptions instead of asking the right clarifying questions first?

The bigger problem was that the feedback loop was completely broken. Books teach frameworks, but can’t evaluate your specific answer. And without a real interviewer in the room, you’re essentially guessing.

On top of that, I kept forgetting how close my interviews were until it was too late to course-correct.

So I built something to fix all three problems — AI Prep Loop.

It simulates a real interview experience: you ask clarifying questions first (just like you would in an actual interview), then give your answer. The AI then scores it across 4 dimensions, the way a real interviewer would — Structure, Depth, Insight, and Recommendation — with specific, honest feedback on what worked and what didn’t. No generic praise.

It also tracks your upcoming interviews and sends you reminders as the date approaches.

It’s completely free, and you don’t need to sign up to try it: aipreploop.com

Would love brutal feedback from this community:

• Is the AI feedback specific enough to actually be useful?
• What question types do you wish there were better resources for?
• What would make you come back to it regularly?

Happy to answer any questions.
