• Quant employment verification: CONFIRMED. Andrea Ciprietti's LinkedIn profile (public page, JSON-LD) lists work experience at WorldQuant, and his headline reads 'Software Engineer @ Google Zurich. Former Software Engineer Intern @ WorldQuant, LLC' - an actual past internship role (not a student program, competition, insight day, camp, scholarship or offer), consistent with the unverified lead of a Software Engineer internship at WorldQuant from Aug 2021 to Oct 2021. WorldQuant LLC is a quantitative investment-management firm (systematic/algorithmic trading), so this is a genuine quantitative-finance employer. Google (current, Zurich) is a technology employer and is NOT a quantitative-finance firm. Conio Inc. is an Italian bitcoin/crypto wallet company (crypto, not a trading/market-making firm); IBM is a technology company. No other quantitative-finance or trading employer appears in any source. Identity is supported: the LinkedIn profile matches the IOI/IMO competitive-programming record (same name, Italy, Pisa/SNS education, cphof Codeforces handle cip999) and lists the same Pisa/SNS schooling and the WorldQuant role. Caveat: employment dates come from the caller-provided lead and are not shown on the public LinkedIn page, so the Aug-Oct 2021 dates remain unverified.
