• Quant employment verification: UNRESOLVED. The LinkedIn-derived index profile for Sanzhar Bidaibek (linkedin.com/in/sanzhar-bidaibek, handle 'sanzhar-bidaibek') lists an in-progress role of Quantitative Developer at Jane Street (Hong Kong, '2022- . 4 yrs') plus prior Jane Street internships (Quantitative Trading Intern 2022; Software Engineer Intern 2021; Software Engineer Intern 2020, postponed due to covid-19). Jane Street is independently confirmed as a quantitative trading firm / liquidity provider (janestreet.com describes itself as 'a quantitative trading firm and liquidity provider'), so the employer classification as quantitative finance is supported. Identity is supported (IOI competitor for Kazakhstan 2016-2018, GitHub SBidaibek, LinkedIn). However, the employment itself rests solely on the LinkedIn index profile; no independent primary source (Jane Street team/news page, press, or the person's own site) was found corroborating the roles, and index-only employment is treated as uncertain. If the index profile is accurate, these are actual employment/internships at a confirmed quant firm, not a student program; on current evidence the role claim is retained as unconfirmed.2022
