What types of consulting do major firms offer, and how do boutiques compare to MBB?
Consulting firms span a wide spectrum, from MBB (McKinsey, BCG, Bain) offering multi-practice portfolios to boutiques with deep vertical expertise. The key difference lies in breadth of work, exit options, and how quickly you can steer your career.
What MBB and Tier-2 Firms Offer
McKinsey, BCG, and Bain operate across strategy, implementation, and technology consulting. You'll rarely choose your practice area in the first 1-2 years; staffing teams allocate you based on project needs and bandwidth. Deloitte, PwC, and EY follow a similar model, though their tech and operations arms are larger than pure strategy. From Reddit, we learnt that analysts at these firms often rotate through 3-4 projects in Year 1, spanning industries from BFSI to consumer goods, which builds versatility but delays specialization.
Accenture and Capgemini tilt heavily toward digital transformation and IT implementation.
Strategy work exists but forms a smaller share of total headcount. If you join their strategy arms (Accenture Strategy, Capgemini Invent), you'll still see cross-staffing into tech-heavy engagements during lean periods.
How Boutiques Differ
Boutique firms like Kearney, Oliver Wyman, L.E.K., and Simon-Kucher specialize in narrower domains. Kearney focuses on operations and procurement, Oliver Wyman on financial services and actuarial work, L.E.K. on private equity due diligence, and Simon-Kucher on pricing strategy. The upside is faster skill depth and quicker promotions due to flatter org structures. You might make Principal in 5-6 years versus 7-8 at MBB.
The trade-off is restricted exit opportunities. If you spend three years doing pricing analytics at Simon-Kucher, pivoting to a general management role at HUL or Asian Paints becomes harder than if you'd rotated through strategy, ops, and M&A at BCG.
Boutique alumni often move to similar boutiques or niche corporate roles rather than broad C-suite tracks.
| Firm Type | Practice Breadth | Promotion Speed | Typical Exits |
|---|---|---|---|
| MBB | Strategy, ops, tech, M&A | 7-8 years to Principal | PE, startups, CXO roles |
| Tier-2 (Deloitte, PwC) | Heavy tech/ops, some strategy | 6-7 years | Industry, internal strategy |
| Boutiques (Kearney, L.E.K.) | 1-2 verticals | 5-6 years | Niche firms, functional roles |
What Drives Partner Progression
Principals and Partners differentiate through selling and people skills, not just technical depth. A Partner at McKinsey spends 60-70% of their time on business development and client relationship management.
Industry expertise matters, but the ability to close a ₹5 Cr engagement and build a 20-person team matters more. On Reddit AMA, we learnt that many high-performing Senior Associates plateau because they excel at execution but struggle with client-facing sales conversations.
If you're targeting consulting post-MBA, compare colleges on placement data by firm tier. Schools like IIM Ahmedabad and IIM Bangalore place 40-50 students annually into MBB and boutiques combined, while Tier-2 B-schools see heavier Tier-2 consulting intake.
Pro Tip: If exit optionality matters more than early promotion, prioritize MBB and Tier-2 generalist roles over boutiques. If you have a clear vertical passion (pricing, PE diligence), boutiques offer faster mastery and Partner track visibility.
