I'm not sure what you want me to respond with. Do you want me to tell you that you can walk in and demand a compensation at the start of your interview or something? Most individuals don't have the bargaining power to do that. If you are desirable enough that the company wants to pay you whatever you ask for, then sure. Go in and talk about money right away.

For most of us, we are competing with thousands of others for one of maybe a few positions. The onus is on us to prove that we are desirable and will provide value, and asking about compensation first does not usually give that impression.
