This is doable with a true/false parameter on the user collection. Call it “onboarding complete”
When a user first signs up, walk them through your onboarding screens where you ask the questions.
On the last onboarding screen, update the logged-in user to mark the onboarding complete parameter as “true”.
On your actual “home screen” (the one users will go to after they’ve answered the questions), add a countdown timer that links to the first onboarding question. Set the visibility of the countdown timer to sometimes visible if logged-in user onboarding complete is false.
This will force the user back to the onboarding questions if the user has not completed the onboarding process.
