I don't think it is a good idea to answer a question with a question especially at a job interview. Give them a figure even if it may be on the high side.'What salary do you expect?' Is it correct to reply 'What salary do you offer usually?'
TryIf I am not satisfied with the salary offered by the interviewer how should I reply?
I am sorry, the salary you have offered is less than what I expect. Would you consider a salary of $xxxx?
not a teaecher
