In about one hour I am going to interview for my promotion in another office. What are some questions I should ask when they ask me if I have any questions?

Don't be afraid to ask about a raise or any other benefits! They want honesty.

Make sure you understand completely what your responsibilities are. If they have failed at describing properly the job mandate ask all the questions that will arise in your head at that moment.

Some interviews are well done, information is clear and precise and you don't need to ask questions. If it's the case just say everything is clear and precise and you have no questions.
