Interview question · Application & API Security

A team shipped an app built with an AI app builder. What would you check first, and why do these apps leak data so often?

The app works, the demo is great, and every row in the database is readable from the browser. The scored answer explains the architecture that makes this common and a one-hour review that catches it.

What if · the follow-ups in this answer

The answer works through 4 follow-ups like an interviewer would

Marketing built a customer feedback portal with an AI app builder in a weekend. A customer reports that by editing a number in the browser's network request, they could see other customers' feedback, including phone numbers.

  1. What is the most likely cause?
  2. What do you do in the first hour?
  3. How do you stop the next weekend project from repeating it?
  4. How do you summarise reviewing AI-built apps?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Premium opens every answer and ladder.
