During job interviews, it's common for interviewers to invite you to ask questions, which can offer insights into your interest in the position and the department or agency you are interviewing with. Your questions show the interviewer that you have done your homework and are keenly interested in the department and the role. It's also an opportunity for you to better understand the job responsibilities, department culture, and potential growth opportunities. By asking questions, you can also demonstrate your critical thinking skills and ability to engage in professional conversation. Overall, it's a crucial aspect of the interview process for the interviewer and yourself.
