Consulting Internship 2026: One Application, Two Seats

A consulting internship runs eight to ten weeks, and at BCG it shares the full-time application. The firms' own pages on screens, timings and a $108,000 rate.

10 min read
In short
  • The seat runs 8 to 10 weeks at McKinsey and 10 weeks at Bain, and one German firm publishes three to six months instead of a summer.
  • BCG's US campus page covers the 2027 Summer Internship and the full-time seat in one application, with one assessment path: the CCA within 48 hours, then an online case of about 35 minutes for a selected group.
  • McKinsey's interviewing page names a personal experience interview and a problem-solving interview for most client-facing roles, and draws no line between interns and full-time candidates.
  • The firm suggests two prepared examples for each of four themes, which is eight stories to have ready before the first round.
  • Bain asks MBA interns for a digital assessment and does not list one for undergraduate interns, so the pieces you owe depend on the program rather than the firm.
  • McKinsey's live Business Analyst Intern posting states a US annualized range of $108,000 to $108,000, which is about $16,600 over eight weeks and about $20,800 over ten.

A consulting internship is a paid summer seat of eight to ten weeks on a client team, and at the firms whose pages we read it is sold through the same door as the permanent job. At BCG it is literally the same application for both. This page opens the live postings and campus pages, quotes what each one requires, converts the one pay figure a firm publishes for the seat, and says where each firm goes quiet.

What the consulting internship actually is, firm by firm

The seat has a published length at every firm we read, and the lengths cluster. McKinsey's Business Analyst Intern posting describes a stay of 8 to 10 weeks on a client service team, working a workstream alongside full-time colleagues, and it asks for an "Undergraduate degree in progress". Bain's two intern programs both run 10 weeks full-time, and the undergraduate one opens with a week of intensive training before anyone meets a client.

BCG states what the seat is for in one line on its internship page: the internship is a foundation from which to apply for a full-time consulting role. Read that as the firm telling you the summer is the interview for the job. For the full directory of named programs, including the ones that run a week rather than ten, see consulting internships by firm and duration.

Outside the United States the shape changes. One German firm publishes an internship of three to six months rather than a summer, with two routes, one on client projects and one in internal functions. A three-month minimum rules out an American summer break, so a student applying across both markets is applying for two different commitments under one word. Our page on what Porsche Consulting is covers that firm's process end to end.

One first-hand account of what the work contains comes from the firm itself. Anna Smolders, writing on McKinsey's careers blog on 15 March 2023 about a Brussels internship that turned into an associate seat, said: "During my internship, I worked on an analytics-fueled approach for product portfolio optimization. I was surprised by the technical content and even did some initial coding with the client's data." One person, one summer, one practice area, so read it as her experience rather than as the shape of every internship. It is still the most specific published description of intern work we found.

Where the three firms put the consulting internship applicant

Three pages, read 30 September 2026, describe what a student owes before anyone speaks to them. The differences sit in the pieces required, and they are firm by firm rather than universal.

Firm and program Stated length Pieces the page asks for Screens the page names
McKinsey, Business Analyst Intern 8-10 weeks undergraduate degree in progress, no cover letter named on the posting test or game depending on role, then personal experience and problem-solving interviews
BCG, US Summer Internship not stated on the campus page resume, two office preferences, cover letter optional CCA within 48 hours, then an online case of about 35 minutes for a selected group
Bain, Associate Consultant Internship 10 weeks, full-time resume, educational background, work experience, test scores if applicable several rounds of interviews, case interview possible
Bain, Summer Associate 10 weeks, full-time the same four, plus a digital assessment several rounds of interviews, case interview possible

Read the last two rows together. Bain's Summer Associate application list carries a digital assessment and asks for relevant test scores without a condition attached. The Associate Consultant Intern list carries neither, and writes "Relevant test scores (if applicable)" instead. Same firm, same ten weeks, different homework.

One BCG door for the consulting internship and the full-time seat

BCG's US Associate campus page, checked 30 September 2026, treats the internship and the permanent job as one recruiting event. Its deadline notice reads: "Applications for our 2027 Summer Internship and Full-Time opportunities have closed. Please check back for future opportunities." One sentence, two seats, one closing date.

The screening sequence that follows is published with its clocks, and it is the same sequence for both. The page states that "CCA invitations will be sent 30-90 minutes after your application is submitted", then that "You will have 48 hours to complete the CCA". The assessment itself takes about 30 to 35 minutes. After that comes a second gate for fewer people: "Select Candidates: Complete the online case (~35 minutes)", invited "~2 weeks after the application deadline".

Two practical consequences for a summer applicant. The assessment lands the same afternoon you apply, so the day you submit is the day you need to be ready. And the eligibility line closes the door from above: "If you are currently pursuing your MBA or other educational degree, you are not eligible to apply for these deadlines." BCG also writes that cover letters are not required for either the summer or the full-time application, which removes a document most candidates spend an evening on. Our BCG ladder page covers which degree opens which rung after that.

McKinsey names two interviews and implies eight stories

McKinsey's interviewing page, checked 30 September 2026, describes the process for "most client-facing roles" and never separates interns from full-time hires. Its core sentence is short: "For most client-facing roles, you will participate in a personal experience interview, followed by a problem-solving interview."

The preparation instruction is where a number appears. The firm suggests "two personal examples that demonstrate how you've made an impact in each of the four areas below". Four themes, two examples each, so eight stories to have ready. That arithmetic is the most concrete preparation target any of the three firms publishes, and almost nobody states it as a count.

Three more lines from the same page matter for a summer round. On volume, "All candidates have at least one individual interview, and the number of colleagues you meet will vary", which means no published round count exists. On the game, the firm says there is no need to prepare for it. And on remote conduct, it asks candidates to "Disable previously installed AI software (such as note-taking tools or virtual assistants), as these may unintentionally record or assist with the interview." That instruction is new enough that a 2024 preparation guide will not carry it. The Business Analyst role page describes the seat the internship feeds.

What a consulting internship pays while you are sitting in it

The intern rate is the one number in this process that a firm publishes directly. McKinsey's Business Analyst Intern posting, job ID 15275, read 30 September 2026, states that "the salary range for new joiners in this role in Canada and/or the United States, including all office locations where the job may be performed, is $108,000 - $108,000 in USD and $99,000 - $99,000 in CAD gross per year".

That is an annualized figure for a stay of 8 to 10 weeks, so it converts. Divide 108,000 by 52 and a week is worth $2,076.92. Eight weeks of that is $16,615.38, and ten weeks is $20,769.23. Call it about $16,600 to about $20,800 in gross base for the summer, before anything a local office adds.

For the MBA seat, two schools publish their own numbers. Cornell Johnson's internship data for the class of 2026 reports 260 of 278 students seeking an internship, 99 percent accepting an offer, and a consulting internship median base of $15,000 a month against an all industry average of $11,132. A month holds 52 divided by 12 weeks, so 4.33 weeks, and ten weeks is 2.31 months. At the median that is 15,000 times 2.31, or roughly $34,650 for the summer. Columbia Business School's 2025 internship report puts consulting at 16.1 percent of its internship offers, with a monthly median of $15,750 and a high of $33,650. At that median, ten weeks works out at 15,750 times 2.31, which is roughly $36,400. Columbia notes that its report includes sponsored students, whom the CSEA standards exclude from ranking submissions, so the two schools are not strictly comparable. Full-time bands sit on our salary guide, and they are a different question from this one.

The interview itself, and what changes for a summer round

Nothing in the three firms' published material describes a lighter case for an intern. Bain's hiring process page says that for most roles "our team will review your application, you might have a call with a recruiter, and you'll have several rounds of interviews", and that a consultant-type role "may also have a case interview where you work through a problem". The word intern does not qualify any part of that sentence.

What the pages do change is the evidence base they expect. McKinsey's intern posting asks for an "Undergraduate degree in progress" and lists the same working conditions as its Associate posting, including the "Ability to work or attend meetings outside of traditional business hours". Bain's undergraduate program is aimed at "current bachelor's and master's students with one full summer left before graduation". So the stories you bring come from coursework, clubs, a first job, or a research project, because that is all anyone in the room expects you to have.

Bain also publishes something useful about feedback: "any feedback you receive will be based on an objective scoring system", and "After each interview, you'll learn exactly how it went." The scoring system itself is not published, which is the constant across every firm we have read.

Five things these firms do not publish

The gap between what is published and what circulates on this query is wide, and it is worth naming item by item.

  1. No acceptance rate. None of the three pages carries one. The figure of under 1 to 3 percent attributed to MBB career pages on this query appears on none of the pages we read.
  2. No round count for interns. McKinsey says the number of colleagues you meet will vary. Bain says several rounds. BCG's campus page stops at the online case.
  3. No scoring grid. Bain names an objective scoring system without publishing it. BCG describes the CCA as giving multidimensional insight without naming a dimension or a weight.
  4. No published difference between the intern case and the full-time case. The absence is itself the answer: prepare for the full-time bar, because that is the only bar anyone describes.
  5. No conversion rate. What a successful internship earns you is written differently by each firm, and we treat that on our return offer page.

One access failure belongs here too. McKinsey's campus deadline page serves its FAQ answers, including "What does the interview process look like?", outside the served HTML. A direct curl is refused by the domain and the text proxy returns only the question titles, so we did not read those answers and do not summarize them.

A consulting internship preparation order that follows the screens

The sequence below follows the order the screens actually arrive in, which is the only ordering these pages justify. It assumes a US campus timeline and the three firms named above.

Step What it is for What the source says
1 Be assessment ready before you submit BCG sends the CCA 30 to 90 minutes after submission, with 48 hours to finish
2 Draft eight experience stories McKinsey suggests two examples for each of four themes
3 Drill exhibit reading and arithmetic under a clock BCG's online case runs about 35 minutes for a selected group
4 Rehearse a spoken case end to end Bain's process includes several rounds and a possible case interview
5 Check the local application list Bain's required pieces differ between its MBA and undergraduate programs

Step 2 is the one students under-build. Eight stories sounds like a lot until you notice that a single project can supply two of them, one about the decision you made and one about the person you had to bring along. Write each as four lines: the situation, the choice you owned, what you did, and the measured result. A story without a number in the last line will not survive a follow-up question.

Two gaps in that plan are worth stating. Deadlines are regional and they move, so the campus page for your school outranks any calendar we could print. And we found no firm-published mid-internship review date, so nothing here tells you when a summer decision is actually made.

Where our drills fit, and what they will not do

The screens above test two separable things: reading a chart and saying what it changes, and holding arithmetic while talking. Both are drillable this week. Our free chart drill and math drill run in the browser without an account, and they return a graded scorecard rather than a solution to read.

The scale behind that grade is ours rather than any firm's. We wrote the weights and they live in our code, published on the method page: for an exhibit question, So what 30, Observation 25, Implication 25, Next test 20. No firm publishes a rubric, and treating our weights as BCG's would be a misreading of both.

Two things the drills will not do. They teach no business content, and they do not stand in for a firm's own screen: our /assessments page states that 0 of 6 simulators are live, on the page itself. What runs today is the drill set and the scorecard. For the CCA and the online case, the page that describes them is BCG's own, linked above, and it is the only description with authority over its own clocks.

Edits the firm and case guides on this site. Reads each claim about a recruiting process back to the firm's own page before it is published, keeps the source ledger dated, and owns the corrections.

How this guide was made

  • Written against a published editorial process, not from memory. Every claim about a firm's process is either linked to that firm's own page or absent. We say what we could not verify rather than filling the gap.
  • Each page carries a dated source ledger, below. When a firm changes a programme or a deadline, the date tells you how far to trust what you just read.

We look for first-hand candidate accounts for every firm guide. Where we found none we could source, the page says so and carries the firm's own words instead. Nothing here is dressed up as testimony, and if your own experience contradicts what you read, tell us and we will correct it and date the change.
