Notes6

• Quant employment verification: NOT CONFIRMED. The sole lead (Virtu Financial, 'Trading intern', 2026) is unsupported: no recruiter post, press item, personal page, or public profile corroborates it, and the identified LinkedIn profile (a Zagreb mathematics undergraduate, born c.2004) shows no such role. Virtu Financial is itself a genuine electronic market maker / quantitative trading firm (NYSE-listed), so the employer would qualify, but there is no supported role and the lead's subject identity is unverified; the uncertainty is retained rather than resolved.Sep 17, 2026
• No employment or internship found: comprehensive name searches in Croatian and English (with and without diacritics) return only olympiad, school and press coverage, and the identified LinkedIn profile is student-only; the caller-supplied 'Virtu Financial trading intern' lead has no corroborating source anywhere in the sweep.Sep 17, 2026
