While interviewing, tell you the truth, we cannot say the actual answer like what we expect, but tell them whatever to gain the job position. For instance, I follow your policy, you can wait and see my work results and then give me suitably....

Why have to wait?
Yet if you confidently believe that you pass the interview,
you can ask them appropriate salary which is fit to your experiences and knowledge!!That's all!!

I love this one...... tell them the truth how much do you want? As before you're applying for that kind of job you might sure it's volunteer or not.
