• Quant employment verification: NOT CONFIRMED. The only software role tied to a firm with 'Quant' in its name is a Software Engineer Internship at QuantCo (Jul-Sep 2022), and QuantCo is a data-science/engineering consultancy (algorithmic pricing, claims management, forecasting for financial, retail, industrial and healthcare clients), not a quantitative investment, trading, market-making or hedge-fund firm. No actual role or internship at a quantitative-finance employer was found; the QuantCo internship is a genuine role but its employer does not classify as quantitative finance.Sep 2022
