The interviewer wants to ensure that all of your questions about the agency or job role are answered during the interview. It is best to ask at least a question or two, showing the interviewer your eagerness to learn all you can. Of course, you want to review the job announcement and research the company beforehand so you are not asking questions that could be found during your research. Some good questions to ask are if you need to clarify anything not on your resume or discussed during the interview, what the onboarding process looks like, the company culture, or what your first week on the job would entail.
