6. Never ask If There’s Any Reason You Shouldn’t Be Hired:  Most of you must be quite curious to know about the job interview results and may ask the interviewer that if there’s any reason for which you are not hired? Although this question gives you an idea about your performance and where you lack, remember that this kind of a question gives the interviewer a reason to think about what’s wrong with you and where you lack, which can also ruin your chances of bagging the offer, says Pamela Skillings, co-founder of job coaching firm Skillful Communications.
