This is your final opportunity to persuade the interviewer that you are the right candidate for the job. Now is not the time to ask questions about holidays, pay or pensions - all these things can be asked later when you get an offer of employment. Now is the time to ask about any reservations that the interviewer may have about your suitability for the role. You will then give yourself one last chance to persuade the interviewer that you are the right candidate for the job.
