If the interview details are to be asked in polite manner then one should be conversant using polite terms e.g. Sentences starting with, ¨If it is possible¨, ¨If you don not mind telling me¨ or ¨if it does not harm the terms and policies of the organization¨ and ¨Can I have the knowledge of¨. Conclusively question construction with ¨Can I¨ or ¨Should I¨ give other person the sense of authority and respect and the conversation is regarded as polite carrying the least risk of offending the interview taker.
