• Quant employment verification: UNRESOLVED. Evidence: his LinkedIn profile and The Org's Jane Street organization page both list a Quantitative Trading Intern role at Jane Street (Hong Kong SAR) starting 2026; no Jane Street primary page (careers, team, or announcement) confirms it, so the role is index/profile-derived only and not independently primary-confirmed. Employer classification: Jane Street is a quantitative trading / market-making firm (confirmed by the firm's own site), so the employer qualifies as quantitative finance. Identity: supported (name, city Hyderabad, IIT Delhi path match the IOI 2022 record). A listed Jane Street SEE IIT Program 2024 is a student lecture program, not employment, and does not qualify on its own. The verdict is UNRESOLVED rather than CONFIRMED because the only role evidence is index/profile-derived, not a primary source.2026
