When interviewers ask if you have questions, it is an excellent opportunity to ask at least one or two questions about the organization or job role. As an interviewer, I am always impressed when candidates ask thought-provoking questions about the company culture, what I like most or least about the company, what the onboarding process consists of, or if anything needs clarification from their interview or CV. However, you want to be sure to ask questions that could not be answered during your research of the NHS, or it will make you look as if you were not diligent in your research.
