We cannot avoid being asked questions in the interview. Sometimes, my mind goes blank.
It is so terrible to be caught unaware.
Admittedly, you can get prepared in advance for the interview, but you cannot cover everything concerned.
Sure. So you should know how to deal with the probable questions and then make flexible reply.
Firstly, your answer should go straight to the point, and be clear and brief.
State your opinion or argument first, and then go on with details.
Never should you give an answer completely beside the point.
If you indeed don't know how to answer, admit it frankly.
Pretending to know when you do not know may expose yourself to ridicule.
Confirm the question if you don't catch it clearly.
Try to avoid the possible duplicate answer if you can.
It can help you leave a deep impression on the interviewer.
