Meta recruiters have bands for each component. Here's how to move toward the top.
Use competing offers. A Google or Amazon offer at a comparable level gives you concrete negotiating power. "Google offered L5 at \450$K TC. Can Meta match?"
Push on equity. If base is near the cap, ask for more RSUs. "I understand base is limited by the band. Can we increase the RSU grant by \50$100$K?"
Ask about refreshers. Understanding the refresher trajectory helps you evaluate the -year picture, not just year .
