Equity Research Full Resume Review

“Stephanie was an outstanding resume reviewer. She replied within a day, gave detailed feedback in every round, and stayed responsive even while travelling abroad. When I explained I was targeting biotech equity research rather than IB, she adapted her advice quickly and showed me how to translate my scientific work into investment language: commercial relevance, diligence skills and outcome-driven bullets, while keeping my technical credibility. She also gave honest, practical advice on public market exposure and certifications. My final resume scored 97 on the AI review. Highly recommend her!”
