This lesson was checked against the sources listed at the end, official pages first. Firm processes change between offices, roles, and years, so use it as a guide and confirm the details in your invitation and with your recruiter.

The interview process, stage by stage

  1. 1Application: Apply online with your CV and office preferences. What it tests: Academic record, experience, and fit with the role.
  2. 2Online assessments: By country. In the US, BCG sends the Consulting Career Assessment (CCA) 30 to 90 minutes after you apply; it takes about 30 to 35 minutes and must be completed within 48 hours of the invitation. BCG then invites selected candidates about two weeks after the deadline to an online case of about 35 minutes. In the UK, a short numerical assessment is part of the application. What it tests: Numerical reasoning, structuring, chart reading, and a clear recommendation under time limits.
  3. 3Skills interview: BCG says this explores your experience, skills, and motivation for joining BCG. What it tests: Motivation and the five core competencies.
  4. 4Case interview: For client-facing roles, a realistic business problem. What it tests: Problem-solving and analytical skills.
  5. 5Team interview: For client-facing roles, interviews with more senior colleagues. What it tests: Problem-solving, analytical, and communication skills at a higher bar.

The assessments it uses and where they sit

  • Online case: BCG gives the US length as about 35 minutes. Prep sites report that it is one business case asked by a chatbot called Casey, mixing structured questions, short typed answers, and a short video summary.
  • Consulting Career Assessment (CCA): for US applicants, sent 30 to 90 minutes after applying, about 30 to 35 minutes long, and due within 48 hours of the invitation.
  • Short numerical assessment: for UK applicants, part of the application.

What varies by office, region, and role

  • Which online assessments you take depends on country and program. The US uses the Consulting Career Assessment (CCA) and an online case; the UK uses a short numerical assessment.
  • The number of interviews in each round differs by office.
  • Application windows differ by country. For example, BCG London lists its 2026 Associate window as 9 September to 18 October 2026 and its 2027 summer internship window as 1 to 24 January 2027. BCG's international opportunities page lists the timing for each country: many European offices hire year-round, the Middle East window for Associates is January 2027, and Greater China's full-time deadline is 18 October 2026. See the recruiting calendar page for more.
  • BCG publishes guidance on where you may use AI in your application. Follow it, and the rules in each invitation.

Points from public candidate accounts and prep sources

  • Reported: you cannot pause the online case or go back to earlier questions once you start.
  • Reported: the online case has about 8 to 10 questions and ends with a recorded one-minute recommendation.
The honest line on assessments

This platform builds the underlying skills these screens test and gives realistic practice in similar formats. It never provides or reproduces a firm's actual test, and firms do not allow AI tools, notes, or outside help during their assessments unless they say otherwise in writing.
