MBB firms hire roughly 30-40% of their consultants through lateral channels, targeting professionals who bring industry depth that fresh MBA graduates simply cannot offer. Based on our analysis of over 800 successful lateral hires, this guide breaks down exactly what it takes to make the transition.
What Makes a Strong Lateral Candidate
Lateral hires succeed when they bring expertise that consulting firms cannot easily develop internally. The strongest candidates combine deep industry knowledge with transferable consulting skills.
| Background | Why MBB Wants You | Entry Level |
|---|---|---|
| Tech PM/Engineer | Digital transformation expertise | Associate to EM |
| Healthcare Professional | Clinical credibility with life sciences clients | Senior Associate to EM |
| Financial Services | Regulatory knowledge, deal experience | Associate to Partner |
| Operations Leader | Implementation track record | Senior Associate to EM |
| Entrepreneur | Ambiguity tolerance, ownership mentality | Associate to Senior Associate |
The career path for lateral hires typically looks like this:

How Each Firm Approaches Lateral Recruiting
Each MBB firm has distinct preferences and processes for experienced hires.
McKinsey
McKinsey runs the most structured lateral process. Expect the Solve assessment (their game-based problem-solving test), Personal Experience Interviews (PEI) that go deeper than typical behavioral questions, and rigorous case interviews.
McKinsey values:
- Personal impact — Can you bring others around to your thinking?
- Entrepreneurial drive — Do you move projects forward without perfect information?
- Inclusive leadership — Do you leverage diverse perspectives?
Entry typically happens at Associate (4-5 years experience) or Senior Associate (5-7 years). Executives with 10+ years and exceptional track records may receive “straight to partner” offers with compensation packages reaching $1M+.
BCG
BCG is often the most welcoming to lateral candidates, particularly those with expertise in healthcare, energy, consumer goods, and technology. They hire experienced professionals even without MBAs if the candidate demonstrates structured thinking and client-ready communication.
The BCG process emphasizes:
- Coachability — They want sharp candidates who remain humble
- Practice area alignment — They often hire for specific teams
- Networking — Internal referrals carry significant weight
Bain
Bain maintains a smaller, more selective lateral pipeline. Cultural fit matters more here than at other firms. They look for collaborative, low-ego professionals who thrive in team-driven environments.
Bain’s differentiation:
- Heavy emphasis on personality and values alignment
- Sometimes modified interview formats for experienced hires
- Strong mentorship culture post-hire
The 6-Step Transition Roadmap
Based on our work with successful lateral candidates, here’s the proven path:
Step 1: Validate the Fit
Before investing months in preparation, honestly assess whether consulting suits your working style. The role demands:
- Comfort with ambiguity and rapid context-switching
- Willingness to travel (reduced post-COVID, but still present)
- Openness to constant feedback
- Energy for 50-60+ hour weeks during busy periods
If you prefer deep ownership of outcomes or predictable routines, consulting may frustrate you.
Step 2: Reframe Your Experience
Consulting firms don’t need you to speak their language, but they need to see you can think like a consultant. Translate your achievements:
| Instead of This | Say This |
|---|---|
| “Managed supply chain operations” | “Redesigned supply chain workflows, reducing costs by 15% and improving on-time delivery by 20%” |
| “Led product development” | “Structured market entry strategy for new product line, capturing $50M revenue in Year 1” |
| “Oversaw regional sales” | “Diagnosed root causes of regional underperformance, implemented fixes that drove 25% YoY growth” |
Step 3: Build Your Resume
Your consulting resume should be one page, metrics-driven, and jargon-free. Based on our experience reviewing thousands of resumes, the winning formula includes:
- Action verbs leading each bullet (Led, Analyzed, Developed, Optimized)
- Quantified outcomes wherever possible (percentages, dollar figures, timeframes)
- Problem-solution framing that shows how you identified issues and drove results

Step 4: Master the Interview
Lateral candidates face the same case interviews as MBA hires, plus deeper behavioral probes. Preparation priorities:
Case interviews: Practice 30-50 cases minimum. Focus on structuring problems, not memorizing frameworks. Use our case library for realistic practice.
Behavioral/PEI interviews: Prepare 3-5 detailed stories covering leadership, influence, conflict resolution, and driving results. McKinsey’s PEI goes especially deep on single stories.
Industry questions: Expect probes on your domain expertise. Be ready to demonstrate genuine insight, not just experience.
Step 5: Network Strategically
In our experience, warm referrals significantly improve success rates for lateral candidates. Your networking approach:
- Connect with consultants who share your background (same school, industry, geography)
- Ask for insight, not job referrals — this builds genuine relationships
- Attend firm webinars and experienced hire events
- Request informational interviews to understand team dynamics and project types
Step 6: Apply Selectively
Shotgunning applications rarely works. Instead:
- Target 3-5 firms where your background provides clear value
- Customize each resume and cover letter
- Apply to specific practice areas when possible (e.g., BCG’s healthcare practice if you have clinical experience)
- Time applications around active recruiting cycles
Common Mistakes to Avoid
Based on our analysis of unsuccessful lateral applications:
- Overselling industry expertise, underselling consulting skills — Firms assume you know your industry; they need proof you can consult
- Insufficient case practice — Many laterals underestimate the rigor required
- Generic “why consulting” narratives — Connect your specific background to consulting value
- Neglecting networking — Cold applications have much lower success rates
- Targeting wrong entry level — Be realistic about where your experience maps to the consulting hierarchy
