Notes2

• Quant employment verification: CONFIRMED (employer evidence is index/aggregator-level, NOT an independent primary source). The person-index record for LinkedIn erik-mjaanes-5b76b7191 lists an actual employment role 'Quantitative Trader' at Jane Street, London (from 2025) and a past 'Quantitative Trading Intern' at Jane Street (2024). Jane Street is a proprietary quantitative trading firm / market maker, so the employer classifies as quantitative finance. A RocketReach contact-aggregator snippet independently labels him 'Quantitative Trader @ Jane Street', corroborating the title (still an aggregator, not a primary source). No Jane Street employee/team page or press item confirms the role directly. These are employment and internship roles (not student programs/competitions), so they meet the CONFIRMED bar; identity is supported by matching name + LinkedIn slug + IMO-linked profile. Residual uncertainty: employer-of-record evidence rests on index/aggregator data only.2025
• Represented Norway at the International Mathematical Olympiad in 2019 and 2020; a search-indexed IMO participant page (participant id 29171) is titled 'Erik Mjaanes - IMO Results'. The IMO site table is rendered client-side, so the participant page body could not be read directly and this remains a search-index claim, not a primary-page read.2020
• Education (index-only): Master's in Industrial Economics and Technology Management at NTNU (2020-2025, 5-year programme), a visiting undergraduate year at Harvard University (2022-2023), and an International Baccalaureate at Oslo International School (2017-2020). The Harvard visiting year sits inside the NTNU window, i.e. a study-abroad exchange rather than a separate degree.2025
• Non-quant work history (index-only): Equity Research Intern at DNB Markets (2022), and two Oslo consulting stints in 2023 - Junior Associate Intern at McKinsey & Company and Visiting Associate, Data Scientist at Boston Consulting Group. These predate the Jane Street internship and sit alongside the Harvard/NTNU years.2023
• Based in London, England (index-only), with the Jane Street internship and full-time role both in the London office; prior roles and education are all Oslo/Norway-based.2025
• Earliest listed role is a seasonal job at Norway Royal Salmon ASA (Kvalfjord, Finnmark) in 2020, the same year as IMO participation and the start of the NTNU degree.2020
