Salary Question:

Whether it's during an interview or on an application, no one wants to answer this question, however it's one that must be asked. Firstly, it's a quick way for employers to eliminate candidates with overly high expectations. It also lets the employer know what they will need to offer you if they decide you're the person for the job.
Answering this question is tricky. If you say a figure that's too high, you're likely out of the running, but if you give a number that's too low, you have undervalued your work and your potential contribution to the company.
