About
Free, sourced practice for growth interviews
growthinterview.org helps you practice the judgment behind growth interviews on your own. It is free, needs no account and runs no AI.
Independent
This site is not affiliated with any company it names, and is not endorsed by anyone quoted. Nothing here describes an official hiring rubric, reveals real interview questions or guarantees an offer.
How the worked examples are made
Kettlewise, a fictional AI meal-planning app, and its users, tests, cohorts, costs and every number in the worked questions are invented for practice. Each question is a separate snapshot, not one continuing case. Each worked answer is one strong answer, not the only good one, and every number in it is recomputed by the site’s checks.
Who it’s for
Growth product managers, growth marketers and lifecycle and experimentation roles, interviewing where you will be asked to read a test result, a funnel or a retention curve and decide what to ship.
About the test readout
The readout uses a two-proportion z-test and a normal-approximation interval, and sizes tests at 80% power. Use it to reason about a result in an interview, not in place of your team’s experimentation platform. It runs in your browser and stores nothing.
How the quotes are checked
Each quote links to where it was published, and we check its exact words against the publisher’s text. A quote is that person’s view, in their role at the time. The interview advice around it is ours.
Privacy and your notes
This site has no accounts, sets no cookies and records nothing you type. Each worked example has an optional notes box. Not saved by this site. Your browser may restore text when you navigate back. Links to Socratify carry a starting prompt written by us, never your notes. Socratify is a separate service with its own privacy policy.
Who publishes it
growthinterview.org is made by Socratify, an AI coach for interview practice.
