Which MBB firms run internships, and how long are they?
Bain's internships and programmes run from two days to a year, and BCG's internships typically run from a few weeks to a year, by their own careers sites.
Bain's internships page lists its Associate Consultant Internship, typically for bachelor's and master's students with one full summer left before graduation, and its Summer Associate programme, for MBA students, as 10 weeks full-time; the Associate Consultant Internship's own page says its length varies by office. BCG runs core consulting internships for undergraduate, advanced degree and MBA students, and digital and technology internships at BCG X and BCG Platinion. BCG London's summer internship is eight weeks through July and August. Our record also follows McKinsey's internship listings, shown with every firm's open roles in the firm table.

What is the MBB internship timeline?
Bain's and BCG's internship deadlines vary by region, role or school location, and BCG's London page gives 1 January to 24 January 2027 as the application window for its eight-week summer internship in July and August.
BCG's US page states that the deadlines for its 2027 Summer Internship and Full-Time Associate applications have passed. Bain says deadlines for its Associate Consultant Internship vary by region, and asks applicants to be on track to graduate by June 2028 where that applies to their office. Bain's MBA Summer Associate programme is expected to run from early June to early August in most locations. The firm table shows how long our record has listed each firm's summer internships.
Bain states a monthly base salary of $9,000 for its Associate Consultant Internship in the United States, on the internship's own page.
Bain's MBA Summer Associates are paid prorated, for the length of the programme, from the $200,000 annual base salary of the comparable full-time position in the US, and Bain says pay outside the US is commensurate with competitive geographic market rates. Bain's Associate Consultant posting gives $120,000 as the annualized base for first-year Associate Consultants in the US. BCG's internship opportunities and US associate pages give no pay figure.
Our record lists 269 roles in graduate jobs at 3 firms in the MBB group for a 2027 start.
Bain's entry consulting role is the Associate Consultant, which its posting calls ideal for final-year undergraduates, non-MBA master's students or early career professionals, with eligibility and deadlines varying by office. BCG's is the Associate: its London page asks for a Bachelor's degree, in the final year or graduated with less than two years of full-time work experience, looks for at least a 2:1, and gave 9 September to 18 October 2026 as its application window. BCG's US page welcomes undergraduate and non-MBA master's students from all fields of study. The firm table shows McKinsey's graduate roles beside theirs.

Bain's Associate Consultant posting, checked 11 Nov 2026
Bain says its consulting process typically consists of a digital assessment and then case interviews, and BCG lists an online application, a skills interview, a case interview for client-facing roles and a team interview.
Bain's Associate Consultant Internship asks for a resume or CV, educational background, work experience and any relevant test scores, plus what the chosen office requires. In the US, BCG asks applicants to complete its Consultant Career Assessment within 48 hours of the invitation, and invites selected candidates to an online case of about 35 minutes around two weeks after the application deadline.
