If the Job-panel asks you '' how much salary do you expect from us''? how should one answer that question?

The standard correct answer is "the going rate for the job".  This is assuming that it is a general interview question and not the opening of an actual negotiation. 

If it is a negotiation, do everything you can to avoid saying any numbers first.  If you have to, state a range remembering that you must be willing to accept the bottom of the range.  From your knowledge of the market, your researches, etc, you should have an idea of what the role will pay, and the range should include that amount.  In other words the range includes what you're hoping for, what you think they'll pay and the lowest amount you're willing to state.  Your actual lowest amount should be below the range you say.

Your current or previous salary is a) irrelevant and b) none of the interviewer's business. 

you have two options most of the time

1) if you are a fresh graduate, you ask for the average salary in the industry for a person with similar education. 

2) if you are an expert, you ask for 25% to 40% more than your last salary considering your education and experience. 

• Companies always have a bracket for the jobs they post, you can answer their question with a question
• Market range, based on experience, skills and qualifications
• Focus on the job itself more than the renumeration
• If they have not mention the salary why you should have to mention your expectation

About me it depend on two things 

First :organization which I will work for , then I will decide 

Second : last salary, I will not down my salary from the last one 

Thanks for invitation,

I do believe that, the answer can be as follows without specifying any figures:

" Not less than any other colleague in the organization, who have same educational background, same experience, same talents and qualifications, and who also already in the same post with same job description".

Our answer shall be according to our past experience , taking in account of our last job salary.

Thank you for invitation. I agree with experts answer.

God, I hate that question, there is hardly a good answer to that one. Agree with Duncan on most points with one exception: if they MAKE you say a figure (i.e. if negotiations are on the way), ANCHOR it high (realistic extreme), so they have to work it down from there..
