Interviewers who ask this question likely want to know how you acted in a real-life situation in which you had to make a sacrifice to stay true to values. If you can tell a relevant, honest story that shows you making a moral decision even when it was hard, you can assure the interviewer that if a similar situation arises at their company, you would still do the right thing. Think about a situation you can share ahead of time to make sure you tell it accurately and effectively.

I received an interview offer 48 hours after my application and I scheduled it for the next week. It was a 30 minute interview with structured question. The interviewer was friendly and it felt like a conversation. This was a seasonal hire: they're mainly looking for how well you can interact with people.
