As a product owner, what are the typical activities done by you?
This is a frequently asked question in Product Owner interview questions.
This would be one of the initial questions, which will help interviewee to open up and also will give interviewer the opportunity to understand the exposure of the candidate.
The answer will vary a bit from candidate to candidate but will typically will be: Sprint Planning, Sprint Review, Sprint Retrospective, and Grooming. If the PO says Daily Scrum (Daily Standup), ask what he does there. It is ok for PO to attend daily scrum, but he just needs to be an observer there and should not speak.
