Millennium

The firm states that prior financial-markets experience is not required; in-depth markets training follows for those who are selected. Because the process is tailored by stream (Quantitative, Engineering and AI, Markets & Products, Business Services) and applicants may submit up to two applications, a candidate covering more than one stream is preparing distinct interview tracks against the same rolling timeline.

In 2025 the firm took 190 interns globally from roughly 50,000 applicants, with about half based outside the US across Bengaluru, Dublin, Hong Kong, London, Miami, New York, Singapore, Tel Aviv, Paris and Zug, per eFinancialCareers coverage of that cycle. The two-application cap means a candidate must decide in advance which two of the four streams and which city to commit to before the August opening, rather than running speculative applications across the platform.

Alongside the four named student streams, the firm runs a separate Meet Millennium immersive program targeted at top undergraduate and master's students in software development and quantitative engineering. For a candidate weighing buy-side seats, this scale of intake across investment, engineering and infrastructure tracks in the same cycle is the differentiator from smaller pod shops where the analyst class is in single or low double digits.
