Google Salary Range: Program Manager

Hello, I have an upcoming Program Manager (non-tech) interview at Google. Couple of questions if anyone at Google can help out 1. What are some questions that are asked during a Program Manager role? 2. This is a non tech role, any tech related questions to brush up on if asked? 3. What is the salary range for this type of role? (I have 10 YOE MBA). 4. When will WFH end for google? 5. WLB for this type of role. 6. Any helpful tips would be greatly appreciated.
