You have good reason to be wary of showing your hand first, especially in an application process, with no ability to elaborate. The old saying, “the first one to speak … loses,” can still hold true in many salary discussions. Network in your field and know your worth. You don’t want to be “lowballed,” but you also don’t want to miss out on a development opportunity.
If a candidate receives a 20 to 30% above-market offer to switch companies, he or she is already excelling in a similar role. Asking for a 20 to 30% increase above market for a role that is a stretch for you may fail. Realistic salary expectations could be your foot in the door. When asked on an application, offer a range that matches where you fit in the requirements of the role. You can also offer to discuss salary further in an interview.
