Tips
Tell a complete story in a single sentence—the challenge, your role, and the outcome.
Instead of just listing your work duties, highlight specific achievements that you accomplished. Here are some examples:
"Negotiated a $5M acquisition, reducing risk exposure by 40%."
"Developed a compliance strategy for a global SaaS company, securing approvals in three regions."
