Before finishing the interview, an interviewer always asks one last question. The question will always be "Do you have any queries?" Many candidates are in a habit of saying" No". By saying "No" to this question, you are indicating the interviewer that you are disinterested in the company or the job. If you do not ask questions to the interviewer, the interviewer may wonder if you would stay away from asking queries on the job. Before going to any interview, you should always be prepared with the list of questions that you would like to ask to the interviewer. Never ask questions about vacation time, salary, employee benefits etc in the beginning. Ask queries that show your eagerness and keenness to work for the company.
