Generally that survey result get discarded; one big trick used by many apps is to have surveys that distract you away from leaving negative results in the appstore or other places where the survey result actually counts.
Seen it a few times, although not so much recently... An app would pop up a rating dialog, asking you to give it 1-5 stars. If you chose 5 stars, it would send you on to the Play Store to leave your rating - if you chose 1-4, it would instead give you an in-app feedback form. They couldn't force you to actually leave a 5 star rating, but it was pretty dodgy anyway.
