Reviewed, sourced research on the firms featured in the public careers page. This is a research snapshot, not a live vacancy board. Check the employer for current details.
Goldman Sachs
The Goldman Sachs Group, Inc. is the US SEC registrant whose 2025 Form 10-K and June 2026 Form 10-Q present consolidated activity. The group reported US$58.283 billion net revenues for 2025 and US$20.338 billion for Q2 2026, the quarter ended 30 June. These amounts include subsidiaries and cannot be attributed to Goldman Sachs International, International Bank or Group UK Limited alone.
Barclays
Barclays PLC's 2025 results distinguish Barclays UK, UK Corporate Bank, Private Bank and Wealth Management, Investment Bank, US Consumer Bank and Head Office. Parent-group results are not the Investment Bank's or a London intern team's results.
BlackRock
BlackRock, Inc. and its subsidiaries provide investment management and technology or subscription services to institutional and retail clients worldwide.
Morgan Stanley
Morgan Stanley reported three consolidated operating lines in Q2 2026: Institutional Securities, Wealth Management and Investment Management. Firm net revenues were $21.348bn, compared with $16.792bn in Q2 2025. These are US parent group figures, not UK subsidiary results.
Boston Consulting Group
The Boston Consulting Group UK LLP is registered as OC359103. Boston Consulting Group Limited (The), registered as 00958970, is separately listed as an active person with significant control of the LLP. The registry does not say which entity would employ a summer intern.
Bain & Company
Bain & Company is a global management consultancy advising leaders, including private-equity firms and portfolio companies, on strategy, technology and organisational change. The firm says it works across 67 cities in 40 countries; this is global footprint, not the size of its London office.
Oliver Wyman
Marsh & McLennan Companies, Inc. changed its public brand from Marsh McLennan to Marsh on 14 January 2026 and renamed the Oliver Wyman Group operating business Marsh Management Consulting, without changing SEC reportable segments. The FY2025 10-K places Oliver Wyman, Lippincott and NERA within that management consulting unit. Separately, Oliver Wyman Limited (02995605) is an active UK company. Its PSC is MMC UK Group Limited (03704258), whose PSC is Marsh & McLennan Companies UK Limited (03053550), all separately registered. Oliver Wyman Services Limited (03023304) and Oliver Wyman Energy Consulting Limited (03752224) are further distinct active UK companies. The control thresholds and common registered address do not identify the 2027 London intern's legal employer or turn Marsh Management Consulting segment results into Oliver Wyman Limited accounts.
FTI Consulting
FTI Consulting, Inc. reports five consolidated segments: Corporate Finance, Forensic and Litigation Consulting, Economic Consulting, Technology and Strategic Communications. Corporate Finance covers transactions, transformation and restructuring; Forensic and Litigation Consulting covers disputes, investigations and data analysis. Economic Consulting includes Compass Lexecon LLC, a separate subsidiary. This segment map is group-level, not a map of UK LLP intern rotations.
