BCG Platinion Case Interview Guide 2026: Format, Cases, and Tech Prep

BCG Platinion is BCG's dedicated technology and IT consulting arm, founded in Frankfurt, Germany in 2000. It now operates as part of BCG X — BCG's technology build-and-design unit — alongside BCG Digital Ventures and BCG GAMMA. With approximately $750M in annual revenue, 1,000+ employees across 45+ cities, and 2,000+ projects delivered in the last two years, BCG Platinion is one of the most active tech consulting practices globally. Its case interviews are fundamentally different from BCG Core: instead of profitability frameworks and market sizing, you will evaluate application portfolios, compare SAP S/4HANA against Oracle Cloud, and design cloud migration roadmaps connecting technology decisions to business outcomes.

This guide covers what BCG Platinion is, how its interviews differ from BCG Core, the four core case types you will face, a tech prerequisites checklist no competitor provides, and a 6-week prep plan. If you are also preparing for BCG Core, pair this with the BCG case interview guide. For firm context, see the management consulting firms ranking.

What Is BCG Platinion? History, Structure, BCG X Context

BCG Platinion was founded in 2000 in Frankfurt, Germany as BCG's response to growing client demand for IT-specific strategy advice. For its first two decades it operated as a semi-independent unit within BCG, taking engagements that standard BCG consultants lacked the IT depth to staff. In December 2022, BCG reorganized its technology-focused entities into a single umbrella brand: BCG X.

BCG X contains three distinct units:

BCG Platinion remains the largest of the three units by headcount and revenue. Its 1,000+ employees operate across 45+ cities on 6 continents, and the firm reported $750M in annual revenue as of its most recent public disclosures. Practice areas include cloud infrastructure (AWS, Azure, GCP), data and AI, generative AI, ERP systems, cybersecurity, and enterprise architecture.

Why the BCG X rebrand matters for candidates: BCG Platinion now recruits under the BCG X umbrella on many campuses, and job descriptions may list "BCG X" rather than "BCG Platinion" specifically. Understand that if you are interviewing for a BCG X role in IT consulting, you are effectively interviewing for BCG Platinion work.

BCG Platinion vs. BCG Core: What Changes in the Interview

The most common mistake candidates make is preparing for BCG Platinion using BCG Core materials. The two interview formats share a recruiter and some process steps, but the case content, required knowledge, and evaluation criteria diverge substantially.

The shift from math-heavy to knowledge-heavy is the defining difference. A candidate who scored at the 90th percentile on BCG Core math practice cases will struggle in a BCG Platinion interview if they cannot explain why a company might choose Azure over AWS for a regulated financial services workload, or what the business case for migrating from an on-premise ERP to SAP S/4HANA Cloud looks like.

For a broader view of how case formats vary across firms, see the case interview frameworks complete guide.

BCG Platinion Case Format: What to Expect

BCG Platinion uses an interviewer-led format with structured written components. The interviewer presents a technology scenario, hands you data exhibits (often architecture diagrams or vendor comparison tables), and asks sequential structured questions. You do not drive the structure in the same way a candidate-led McKinsey case requires.

A standard BCG Platinion interview runs approximately 45-60 minutes:

• 5 minutes: Case setup and context
• 30-35 minutes: Structured case questions, exhibit analysis, technology decision recommendations
• 10-15 minutes: Fit and behavioral questions

The "structured written components" refers to a common BCG Platinion format where candidates are given a prompt and asked to write a brief recommendation memo or framework on paper before presenting it verbally. This is less common in first rounds and more frequent in final rounds or written case formats.

Four Core BCG Platinion Case Types

1. IT Transformation

The scenario: A client has an aging IT landscape and needs to modernize. You are handed a portfolio of 200+ applications and asked to rationalize, consolidate, or replace them.

What the interviewer tests:

• Can you build a prioritization framework for a large application portfolio?
• Do you understand the distinction between custom-built vs. COTS (commercial off-the-shelf) applications?
• Can you connect each rationalization decision to a business outcome (cost reduction, speed, risk reduction)?

Worked example: A European bank has 240 applications in its portfolio. 80 are core banking. 60 are reporting tools. 100 are "shadow IT" — built by business units outside the IT function. The interviewer asks you to structure an approach for rationalizing the portfolio over 3 years. A strong answer segments the portfolio by business criticality and technical health, identifies quick wins (retire or consolidate low-criticality, low-health applications first), and builds the business case using TCO reduction as the primary metric. For a 240-app portfolio, BCG Platinion engagement teams typically target 30-40% reduction in application count over a 3-year program — translating to meaningful license, maintenance, and support cost savings.

2. ERP Selection

The scenario: A client is replacing its legacy ERP system. You must evaluate SAP S/4HANA against Oracle Cloud (or sometimes Microsoft Dynamics) and recommend a platform.

What the interviewer tests:

• Do you know the basic functional differences between SAP S/4HANA and Oracle Cloud ERP?
• Can you define vendor evaluation criteria tied to client requirements?
• Do you understand implementation complexity, total cost of ownership (TCO), and vendor lock-in risk?

Key knowledge: SAP S/4HANA is the dominant ERP in manufacturing, utilities, and large European enterprises. Oracle Cloud ERP is stronger in financial services and US-headquartered multinationals. Implementation timelines for both run 18-36 months for large enterprises. A typical ERP migration for a mid-size company ($1B revenue) carries a total program cost of $15M–$50M.

3. Cloud Migration Roadmap

The scenario: A client wants to migrate from on-premise infrastructure to cloud. You must design the migration roadmap across AWS, Azure, or GCP.

What the interviewer tests:

• Do you understand the "lift and shift" vs. "re-architect" vs. "replace with SaaS" decision logic?
• Can you prioritize which workloads move first?
• Do you understand the cost model differences between CapEx (owned hardware) and OpEx (cloud consumption)?

Key knowledge: Cloud migrations are phased. Dev/test environments migrate first (low risk, immediate cost savings). Core transactional workloads (ERP, CRM) migrate last (high complexity, high risk). A typical BCG Platinion cloud migration engagement covers 3 phases over 18-24 months, with roughly 60-70% of workloads moving in the first two phases.

4. M&A Technology Due Diligence

The scenario: A private equity firm or strategic acquirer is evaluating a target company. You are asked to assess the target's IT landscape as part of due diligence.

What the interviewer tests:

• Can you identify technology risks that affect deal valuation?
• Do you know what questions to ask about technical debt, cybersecurity posture, and integration complexity?
• Can you quantify IT integration costs and timelines as inputs to the deal model?

Key knowledge: Common red flags in M&A tech DD include: heavily customized legacy ERP systems (expensive to integrate), outdated cybersecurity controls (liability risk), undocumented technical debt (hidden remediation cost), and multiple conflicting CRM or data platforms. A typical IT integration program for a $500M acquisition runs $5M–$20M and 12-24 months. See the M&A case framework guide for the broader transaction framework.

Tech Prerequisites Checklist: What You Must Know Before Your Interview

This is the section no other BCG Platinion prep resource provides. BCG Platinion does not expect you to be a software engineer or cloud architect, but it does expect fluency in core IT concepts at the level of a first-year tech consultant. If you cannot discuss these topics confidently, you will lose points regardless of how strong your case structure is.

Connecting Technology to Business: The Core Skill

BCG Platinion interviewers are not testing whether you can design a cloud architecture. They are testing whether you can connect technology decisions to business outcomes. This is the single most important evaluation criterion.

Every technology recommendation you make in a BCG Platinion case must answer three questions:

1. What does this technology decision cost? (TCO, migration expense, license fees)
2. What business outcome does it enable? (cost reduction, speed to market, risk reduction, revenue growth)
3. What are the risks and how do we mitigate them? (implementation complexity, vendor lock-in, operational disruption)

Example of a weak answer: "I recommend migrating to AWS because it is the market leader and has the best services."

Example of a strong answer: "I recommend migrating to AWS for this workload specifically because: (1) the client's primary workload is data analytics, where AWS Redshift has demonstrated 30-40% performance advantages over comparable on-premise solutions; (2) the client is already paying for AWS support contracts on other workloads, so incremental costs are lower; and (3) migrating to a single cloud provider reduces operational complexity by eliminating the multi-cloud management overhead the client currently pays $2M annually to support."

The difference is specificity, numbers, and business logic — not technical depth. See the case interview hypothesis-driven approach for the underlying thinking structure.

BCG Platinion Salary, Career Path, and Culture

Compensation

BCG Platinion compensation at the Senior Consultant to Manager level runs approximately $181K–$201K total compensation, according to data aggregated from sources including Glassdoor BCG Platinion profiles and Levels.fyi BCG data. This is slightly below BCG Core at equivalent levels, which tends to run $10K–$25K higher. Both firms follow the same promotion cycle: approximately 2 years at each level from Consultant to Project Leader to Principal to Partner.

For a complete picture of consulting compensation across firms, see the consulting salary guide.

Career Path

BCG Platinion's career path mirrors BCG Core at the titles but differs in the daily work:

Alumni from BCG Platinion move into CTO, Chief Digital Officer, and VP of Technology roles at major corporations, as well as into private equity technology operating partner roles.

Culture

BCG Platinion operates with more specialized teams than BCG Core. Projects are staffed with consultants who have deep expertise in a specific technology domain — cloud, ERP, cybersecurity — rather than generalists who rotate across topics. This means culture is more "depth-first" than BCG Core's "breadth-first" model. Expect to develop real expertise in one or two technology areas over your first 2-3 years. For context on consulting culture broadly, see the day in the life of a management consultant guide.
