What is better to answer during the interview with HR and FOM to the question: what kind of salary do you need?

Any of the questions related to Salary should be dealt wisely. Always keep in mind not to give a fixed salary, and embrace a strategic approach, like negotiating on the benefits. As you are asked the questions, let the interviewer explain upon your responsibility. And make them understand that you are aware of the job market. (of course you should do a thorough research). Be practical in your expectation. At last, it is your choice whether you accept the position....

Gud Luck...
