What is the salary that you expect?

We all have different financial situations, and that is okay. If there is a specific dollar amount that you need to make, share that with the interviewer, but understand that you might eliminate yourself from the candidate pool if the amount you require is higher than they can offer you. It's better to find this out sooner rather than later!
If you do not have a specific dollar amount that you need, tell the interviewer that you would like to receive an offer that is equitable for the amount of experience and qualifications that you offer. This leaves the table open for negotiations, come job offer time!
