BCG Platinion Interview: A Logic Test and Two Cases

Where the process is published, and how to read it

The application process page states the floor first: "Our application process consists of a minimum two rounds of interviews, including case studies." Minimum is the operative word, and the page says so again later, in the line "Additional interviews may be required, depending on specific cases."

The page then lays out several versions of the same pipeline side by side. The versions are real and they differ from each other, but the site does not put a readable label on any of them in its text. We could not tell from the page which column belongs to which country or role, so we quote them as variants and leave the attribution alone. That is the honest treatment, and it still leaves you with the whole range of what can arrive.

One more thing sits on that page and is easy to miss. For client-facing roles the firm writes that it will assess "your problem-solving and analytical skills, as well as your IT skills, offering the necessary support and resources to help you prepare effectively for the interview." Three things get read in the same conversation.

The criteria, meanwhile, look familiar. Platinion lists intellectual curiosity, creative thinking, integrity and a collaborative attitude. BCG's interview process page lists integrity, intellectual curiosity, creative thinking, collaborative mindset and drive. Different steps, near-identical language about what is being judged. Our BCG guide covers the consulting sequence in full.

The rounds, as the firm numbers them

The application bundle also varies by variant: CV with a project list, or CV plus references and transcripts, or CV plus university transcripts and a motivation letter. The project list is the unusual one. It asks you to name consulting projects or cases you have worked on, which is a document most candidates do not have ready.

Two administrative facts from the FAQ page round this out. The firm writes "We aim to respond to you within a week to advise you either way," which is a faster commitment than most careers pages make. And on background it writes that for IT architecture or IT consulting "you will be expected to have a degree in an IT or business-related subject as well as proven practical experience as a minimum."

The logic test, and the round with two case interviews

The logic test appears in one variant only, with one line of detail: "Logic test completion within 1 week before interviews." So it is scheduled against your interview date rather than against your application date, and the firm publishes nothing about what it contains. No provider, no duration, no question types. If your invitation names it, ask the recruiter what it measures. That question is fair and it is cheaper than guessing.

The two-case variant of round two is the more interesting one. Its content list names an "IT case study similar than round 1", a "Business case study", and interviewers described as "One interview with BCG Platinion Director, one with BCG leadership team member". A candidate who meets that variant is being read twice on different ground: once on an architecture problem and once on a commercial problem.

Preparing for both is less work than it sounds, because the second half is the more familiar one. The business half is the exercise BCG describes on its case interview preparation page, where the firm writes that "there isn't always a single 'right' answer" and names six behaviors to show and six to avoid. The gap that costs candidates is the other direction. An IT case asks you to hold a business objective and a technical constraint in one answer, and to say out loud which constraint is binding. Legacy interfaces, data migration, vendor lock-in and release risk are the constraints that recur, and the answer that wins is the one that prices them rather than listing them.

Seven instructions BCG Platinion prints for the case

The preparation page publishes seven numbered instructions for the case itself. Four of them are specific enough to change what you do on the day.

1. Break it down first. "Structure your approach by breaking the problem down into smaller pieces or stages."
2. Stop hunting the perfect answer. "Focus on demonstrating a logical thought process and don't worry too much about finding the perfect solution; there isn't just one correct answer."
3. Work from a hypothesis. "Use a hypothesis-driven approach to work through case studies."
4. Say your assumptions out loud. "Make assumptions and calculations explicit so the interviewer understands your thought processes."
5. Close the loop. "Take the time to conclude and refer back to the original question or task."
6. Slow down. The page adds "Take your time and don't jump to conclusions."
7. Be ready for numbers. "Depending on the role you are applying for, make sure you are comfortable with numbers, important KPIs, and that you possess the required business judgment."

The same page points to two sample IT cases hosted by an outside preparation site. We name the fact and skip the link, because that site competes with us and citing it would be a favor to nobody reading this. The firm publishes no case of its own.

One small instruction on that page is worth obeying literally: if the interview is virtual, keep the camera on and look at the interviewer. Platinion writes it as a rule rather than as a hint.

A build against buy case, worked in dollars

Claims automation at a mid-size insurer, which is the shape a Platinion case tends to take.

The insurer handles 1.9 million claims a year. Manual handling averages 11 minutes per claim, at a fully loaded $38 an hour. Eleven minutes is 0.1833 of an hour, so the labor cost per claim is about $6.97, and 1.9 million claims at $6.97 is about $13.2m a year.

An automation layer is expected to remove 40% of those minutes. Forty percent of $13.2m is roughly $5.3m of annual benefit. Now the two options.

Buying pays back in half the time and earns less by year five. The crossover is worth finding aloud, because it is the whole answer: cumulative build is $4.3m a year minus $9.0m, cumulative buy is $2.7m a year minus $3.0m, and those meet when $1.6m a year closes a $6.0m gap, at 3.75 years.

So the recommendation is a sentence about lifespan. "Buy, unless the claims platform is expected to stay in service beyond about four years, because that is where the build overtakes it. The risk is integration overrun, which lands on the build case twice: it delays the benefit and raises the up-front number. I would test the vendor's migration estimate against two reference clients before committing."

Watch what the 40% is applied to. It is 40% of handling minutes, which is why it becomes 40% of the labor cost. It is not 40% of claims, and it is not 40% of claims cost, which includes the payouts. Naming the base out loud takes four seconds and it is the difference between a defensible number and a lucky one.

What we mark an answer like that on

No firm publishes a marking scheme, Platinion included. The weights below are ours, applied by our own grader, each out of a hundred, read from the code that scores. The reasoning sits on how an answer is assessed.

What BCG Platinion does not publish

Which variant applies to you. The process page shows several and labels none in its text. Your recruiter call, which the firm puts at round zero, is the place to ask.

Anything about the logic test. No provider, no length, no content.

Any case of its own. It points to an outside site instead.

Interview length, or the number of cases in total. Neither appears anywhere on the site.

Whether BCG's own consulting assessments apply. The four steps on BCG's interview process page never name Platinion, and Platinion never names them. Our BCG X guide hits the same wall on the other technology unit.

Any threshold or weighting. None, for any stage.

Two things the firm does publish, and they are worth ending on. The ladder is named in full on the AI Tech Consultants page: AI Tech Associate, AI Tech Consultant, Senior AI Tech Consultant, Manager, Principal, Director, Managing Director. And the firm states that within the consulting track "there is flexibility to transition to the Architecture track, should your skills align". Everything above was read on the page it is credited to, on 29 September 2026, and the scoring weights are ours.
