Google People Operations Rotational Program interview questions

Applied on company website. They got back to me the next day to schedule a phone screen later that week. Had the phone screen with recruiter. They got back to me shortly thereafter that I was not a fit. I followed up with them to try to ask more about what they were looking for, and although they agreed to speak with me, they refused to tell me anything. They claimed that that information was confidential and they couldn't share that with me.
