This question attempts to make the candidate a little confused and nervous so that the interviewer can gain by striking the deal with you towards the lower end of the salary scale. It’s very similar to a business deal where a buyer tries to get the product at the lowest possible price. It is you who has to take charge of the situation and make sure that YOU DON’T SELL YOURSELF FOR LESSER THAN WHAT YOU DESERVE.
The following guidelines  might help you:
  1. Be bold and don’t  hesitate while answering.
  2. Research about what  average salary is being offered in the industry for this role and  responsibility. Tell the interviewer about it.
  2. Don’t make demands, instead ask questions.
  3. Don’t give a particular figure. State a  salary-range based on your research. Make it evident that you are ready to walk  off the job if the lower extreme of the range stated by you is not crossed. 
4. Advice: If the job profile shall provide you  with the opportunity that you needed for paving your career or if it shall help  you learn new skills and provides scope for improvement, then CONSIDER the  decision of settling down at the lower range of the salary-scale. But, here  also, never agree for a pay which is less than the current salary hat you are  getting unless you want to switch the industry or make changeover in your  career path.

Now, it’s time for 'participation':
*Assume that you are sitting in the interview room now.
*You have been asked to ‘ What salary do you expect’. Go ahead; give it a try on how to answer the same. Post your own answers and get them reviewed .
