Interview Cracking Tip

Accept that you knew it, or act as if you are solving it

There are few famous questions in programming that almost everybody would answer in this world, not because its easy, but because the questions are famous enough that any beginner would not have missed it. 

For example, 'WRITE A PROGRAM TO SWAP 2 NUMBERS WITHOUT USING TEMPORARY VARIABLE'. This is one of the famous question for which most of them would know the answer. 

If you already know the answer, tell the interviewer politely that, 'Sir, I knew the answer for this earlier itself as I had seen this in one of the job interview blogs on the internet. Shall I go ahead and write the code ?'. This polite request will definitely impress the interviewer with your honest behaviour.

The other way to tackle this is, if you knew the answer before, do not start writing the code directly, rather, start scribbling on the scrap sheet as if you are hearing the question for the very first time and act as if you are very interested to solve it. And after few seconds of scribbling arrive at an answer as if you solved it now right in front of the interviewer. 

BEWARE! If you directly write the code in excitement seeing the question that you had heard before, it will cost you heavily, as it shows you are good at memorising the code.
