TL;DR. Tier 2 firms (Roland Berger, Oliver Wyman, Kearney, Strategy&, L.E.K.) and Paris boutiques (Advancy, Estin, CVA, eleven, Square) hire differently from MBB: sectoral cases, fewer rounds, fit-heavy. Roland Berger is the 4th most attractive firm in 2025, Oliver Wyman employs 225 consultants in Paris, and Advancy hired 30 profiles in 2024. 3-week prep plan + full map below.
You're aiming for strategy consulting but not (only) MBB? Good news: the Paris market holds more than 30 serious firms.
And 31% of strategy & management engagements focused on industry in 2024 (Syntec, cited by Consultor) — the playing field of Tier 2 and boutiques, not generalist MBB.
Do you know why an L.E.K. case has almost nothing in common with a McKinsey case? Let's break it down.
MBB in 2026: what you need to know in 3 paragraphs
McKinsey, BCG and Bain remain the references but their process fits in one sentence: 2 rounds, generalist cases (PEI/Casey), 1 case + 1 fit per interview. The big 2025 update: since April, McKinsey offers post-screening candidates a free AI coach for quantitative case practice (Consultor 2025).
This move is a direct response to paid prep programs charging over 2,000 € per candidate. If you're targeting MBB, we have a dedicated guide: MBB interview France — McKinsey, BCG, Bain.
This article zooms deliberately on Tier 2 and boutiques, because their combined Paris hiring volume outweighs the three MBB combined — and their interviews call for a different, more sectoral prep.

Tier 2 vs MBB: 4 process differences that reshape your prep
First things first: Tier 2 firms aren't "MBB-lite". They play a different game.
1. Number of rounds. Roland Berger, Oliver Wyman and Strategy& usually run 2 rounds, where MBB runs 2 to 3. L.E.K. starts with an online numerical test in English followed by 2 interview rounds (Consultor — L.E.K.). Fewer filters doesn't mean less demanding.
2. Sectoral cases vs generalist cases. McKinsey will hand you a "how to grow market X". An L.E.K. partner will hand you a due diligence on a PE target with 4 tabs of hard numbers. An eleven partner will ask for a business case on generative AI in a specific sector.
3. Weight of fit. At eleven, the process runs 4 rounds for juniors / 5 for seniors, with 1 case + a fit portion per round (Consultor — eleven). Across 4 rounds, cumulated fit weighs as much as the case. Your stories must be ready — not improvised.
4. Candidate signal to factor in. Kearney Paris lost 15 partners out of 32 in 15 months in late 2024-2025 (Consultor — Kearney). Before signing, ask who leads your practice and for how long.
Tier 2 map in Paris: specialties and what they want
Five firms dominate the Tier 2 category in Paris. Here are the numbers and the DNAs.
Roland Berger moved up to 4th most attractive firm in 2025, ahead of Oliver Wyman (5th), EY-Parthenon (6th) and Strategy& (10th) (Consultor 2025 ranking). About forty partners in Paris, industry/defense/health DNA. It's currently the hottest Tier 2 for engineering profiles.
Oliver Wyman employs 225 consultants (including 38 partners) in Paris, €120M revenue, 50 new junior hires per year and 18% annual attrition (Consultor — Oliver Wyman). Wholly owned by Marsh McLennan. Ten partners in financial services — its historical specialty — plus telecoms/media, transport and consumer goods practices.
Strategy&: roughly 200 consultants in Paris out of 4,000 globally, and Consulting weighs 42% of PwC's global revenue (Consultor — Strategy&). Strong deals/PE and tech exposure, progressive integration with PwC audit.
L.E.K.: 14 partners, around 100 consultants in Paris, and a junior runs 8 to 12 due diligences per year on short 3 to 6-week engagements (Consultor — L.E.K.). It's the PE firm by excellence — if you target private equity, target L.E.K.
Kearney: red alert on the Paris partnership as flagged above. The firm is still hiring, but tread carefully.
Paris boutiques: Advancy, Estin, CVA, eleven, Square
Boutiques punch above their weight. Here are the 5 to know in 2026.
Advancy hired 30 profiles in 2024 and claims a doubling of its Paris headcount every 5 years (Consultor — Advancy). Founded by Éric de Bettignies, the boutique runs 50% of its activity on chemicals & decarbonation and signs landmark restructuring engagements (Casino, Orpéa, Pierre & Vacances, Lapeyre).
Estin: pure strategy and private equity play, lean team, highly selective. Ideal if you want PE without the L.E.K. pace.
CVA (Corporate Value Associates): 40 consultants in France, 200 globally, integrated EMEA zone of 80 consultants (Consultor — CVA). Founded in 1987 by Paul-André Rabate (ex-BCG, Mars & Co). Structured around disruptive platforms: mobility, energy transition, food transition, distribution.
eleven: founded in 2008, backed by Andera Acto, positions itself as "the firm dedicated to the AI revolution". Process 4 rounds juniors / 5 seniors, cases tilted toward digital/innovation/data science. Very different from classic profitability cases.
Square: financial advisory and data hub, sustained growth, hires quantitative profiles with a real consulting fiber.
Operational 3-week prep plan (D-21 → D-1)
A cadence that works, tested by Velyq candidates who landed offers in 2025-2026.
Week 1 — D-21 to D-15: sector coverage. 5 targeted cases (1 industry, 1 PE/DD, 1 digital, 1 financial services, 1 consumer goods) + systematic reading of Consultor's firm pages for your targets. Identify 3 recent deals per firm — you'll use them in the fit portion.
Week 2 — D-14 to D-8: intensity. 8 live mock interviews, ideally 4 cases + 4 fit segments. Focus on mental math and sectoral market sizing (size of the European specialty chemicals market, size of the French PE DD market, etc.). Film yourself on 2 mocks to spot your tics.
Week 3 — D-7 to D-2: final simulation. 3 simulated "final round" mocks in partner-style format (1h, case + fit + open discussion). Reread your fit stories: CV story, firm motivation, leadership moment, failure moment.
D-1: zero cases. Sleep, quick re-read of the target sector's P&L template, scan of firm news on Les Échos and Consultor. Nothing more.
Total cost of this plan: zero. McKinsey AI coach if you're post-screening MBB, otherwise generic AI simulators and peer-to-peer mocks. Paid prep programs at over 2,000 € are not essential.
2026 Tier 2 + boutique salaries vs MBB and target schools
The junior package delta isn't as wide as you'd think. At entry, MBB sits around €80-90k base + bonus + signing, Tier 2 (Roland Berger, Oliver Wyman, Strategy&) around €65-78k, and serious boutiques (Advancy, Estin) around €55-70k depending on profile. For details, see our strategy consulting salaries 2026 guide.
Target schools are stable. The Consultor 2025 panel — 635 final-year students — concentrates on 7 schools: CentraleSupélec, ESSEC, ESCP, HEC, Mines Paris, Ponts, Polytechnique (Consultor 2025). These are the top French engineering and business schools.
Edge cases: industrial boutiques like Advancy are more open to Mines/Ponts/Centrale profiles and value a strong industry coloring. L.E.K. values finance/PE profiles with solid modeling skills. eleven willingly hires atypical data science and tech profiles.
Frequently asked questions
Should you target MBB before Tier 2, or apply everywhere in parallel?
Apply in parallel, but align your deadlines. An active MBB process can strengthen a Tier 2 application. Avoid 12 firms at once — quality over volume. Target 4 to 6 firms that match your profile.
Is the Tier 2 case easier than the MBB case?
No, it's different. Fewer rounds but more sectoral cases: DD at L.E.K., digital at eleven, industry at Roland Berger. Master the firm's target sector, not just generic frameworks.
Is Kearney still hiring in Paris in 2026?
Yes, but after 15 partner exits out of 32 in 15 months in late 2024-2025, check the practice recruiting you and the tenure of the partners interviewing you.
Does a Paris boutique carry as much weight as an MBB on a CV?
For the French market — corporate, PE, startups — yes: Advancy, Estin, CVA are recognized. For an international exit, MBB stays more universal.
How many cases before a Tier 2 interview?
15 to 25 cases over 3 weeks, with at least 5 in the firm's sector. 20 sectoral cases beat 50 generic ones.
Is McKinsey's AI coach available to Tier 2 candidates?
No, it's reserved for McKinsey post-screening candidates. But its logic — timed quantitative case, market sizing — transfers cleanly to a generic AI simulator.
Do you need a 2,000 € paid coaching?
Not mandatory. Peer-to-peer mocks + free resources + alumni feedback from your school cover 80% of the need.
Which target schools for Roland Berger or Advancy?
Engineering profiles: Mines, Ponts, Polytechnique, CentraleSupélec. Business profiles: HEC, ESSEC, ESCP. The Consultor 2025 panel confirms these 7 schools.
How many rounds at eleven?
4 rounds for juniors, 5 for seniors, 1 case + fit portion per round, cases tilted toward digital/innovation/data science.
When to apply for a September 2026 start?
Tier 2 firms and boutiques hire on a rolling basis: apply between January and May to maximize your chances before classes fill up.
