Interns are placed across technology, post-trade, sales, operations, and other functions, and run out of offices including New York, London, Singapore, and Amsterdam (the firm lists thirteen offices on its about page). Because the analyst headcount comes substantially from returning interns, the meaningful entry decision for a penultimate-year student is whether to apply to the summer program a year before they want to start full-time.

The firm runs Open Trading, an all-to-all venue for institutional bond trading, and serves more than 2,000 investors and broker-dealers – the most of any platform worldwide, by the firm's own claim – with its strongest franchise in US corporate credit. Its footprint spans thirteen offices across North America, South America, Europe, and Asia. For an applicant, that profile means roles sit in fintech and market-infrastructure work rather than at a sell-side dealing desk or a buy-side fund; the work is building, selling, and operating the platform, and New York is the centre of gravity for client-facing teams.
