Gartner Case Interviews: How to Prepare and What to Expect

If you're applying for a consulting role at Gartner, you'll likely encounter one or more Gartner case interviews. These interviews are designed to evaluate how you think, communicate, and solve problems in real-time, mimicking the challenges consultants face on the job. Understanding the format and expectations is key to success.

In this article, we will explore the full structure of Gartner case interviews, preparation strategies, and how to stand out in both the written and live formats.

What are Gartner case interviews and why do they matter?

Gartner case interviews are problem-solving assessments that simulate real consulting scenarios to evaluate your business judgment, structure, and communication skills. These interviews are a core part of the Gartner consulting interview process.

Case interviews at Gartner are candidate-led, meaning you're expected to drive the discussion by asking relevant questions, building frameworks, and proposing solutions.

They typically involve:

• Hypothetical business problems based on real industries
• Qualitative and quantitative analysis
• Communication of structured recommendations

Success in these interviews demonstrates your readiness to handle the analytical and client-facing demands of consulting roles.

How is the Gartner case interview process structured?

The Gartner interview process typically consists of three main rounds, combining behavioral interviews, case interviews, and a written case interview presentation. Each stage is designed to assess different competencies required for a consulting role.

Here’s how the process usually unfolds:

• Round 1: A 30 to 40-minute phone screen with a recruiter, focusing on behavioral or fit questions.
• Round 2: Two 30 to 40-minute virtual or in-person interviews with consultants or partners, involving both case interviews and behavioral questions.
• Round 3: Three back-to-back interviews, featuring a mix of advanced case and behavioral questions, along with a one-hour written case study that includes a formal presentation to a panel.

Throughout the process, Gartner assesses:

• Analytical problem-solving
• Structured thinking
• Communication under pressure
• Culture and team fit
• Business judgment

Each round increases in depth and complexity, so preparation must be layered accordingly. You should be ready to shift between structured problem-solving and authentic storytelling across all stages.

What types of case formats might Gartner use?

Gartner uses several types of case interview formats including live business cases, written case studies, and market-sizing problems. These formats assess your structured thinking and practical consulting skills.

The main types include:

• Live case interviews: Candidate-led problem-solving sessions based on business scenarios
• Written case interviews: Take-home exercises requiring slide development and a formal presentation
• Market-sizing questions: Quick estimation-based exercises to test logic and numeracy

Each format emphasizes clarity, logical flow, and evidence-backed recommendations.

How can you prepare frameworks for Gartner case interviews effectively?

To prepare effective frameworks for Gartner case interviews, you should practice building flexible structures that break down problems into logical, actionable parts.

Start with these principles:

• Clarify the objective before diving into analysis
• Use MECE (Mutually Exclusive, Collectively Exhaustive) buckets
• Balance qualitative and quantitative factors
• Prioritize the most impactful drivers

Examples of frameworks:

• Profitability: Revenue - Cost Drivers
• Market Entry: Market size - Competition - Barriers - Capabilities
• M&A: Strategic fit - Synergies - Financials - Risks

Customizing your framework to each case shows creativity and adaptability, which Gartner values highly.

What behaviors and soft skills does Gartner assess in case interviews?

In addition to problem-solving, Gartner assesses your communication skills, coachability, business presence, and how well you take feedback. These traits are just as critical as technical ability.

Gartner looks for:

• Clear and concise communication

Showing maturity and self-awareness can differentiate you from other strong technical candidates.

Steps to master it:

• Identify the key question and align your structure around it
• Build a 4 to 6-slide deck with clear titles and one insight per slide
• Support your recommendation with 2 to 3 key data-backed reasons

Practice delivering your presentation out loud, anticipating questions from the panel.
