Push notifications within a mobile application are a double-edged sword. They can be useful to notify the user of issues they need to be aware of, input the application requires, and other actions the user needs to take. However, they can also be intrusive, distracting the users and degrading the user experience. Since you don't know how the interviewer views push notifications, you should answer this question directly and honestly, based on the experience you've had developing other mobile applications. It would be best to emphasize that you try to maintain a delicate balance between useful and annoying push notifications. Your answer should also include how you and enable end-users to disable certain types of push notifications.
