How to Prepare for Lazard Interviews
Prepare for Multi-Step Quantitative Derivations
Lazard's technical session includes problems where you derive multiple financial metrics from a few given ratios, such as starting with total assets and a leverage ratio to calculate debt, equity, market cap, net income, and enterprise value. Practice these chain calculations until you can work through them fluidly without second-guessing intermediate steps.
Know IRR Rules of Thumb and Bond Math Shortcuts
The technical interview tests mental math shortcuts including the rule that doubling your money in three years is approximately 26 percent IRR, tripling is approximately 44 percent, and the bond YTM approximation formula. Lazard values quantitative fluency and expects you to estimate these without a calculator.
Quantify Your Behavioral Examples With Real Numbers
Lazard's behavioral session rewards candidates who can attach specific numbers to their stories, such as describing a five-year NPV analysis that saved four hundred thousand dollars on a vendor contract. Prepare your behavioral answers with concrete financial metrics that demonstrate you think quantitatively even outside of technical questions.
Prepare a CEO Advisory Framework
The behavioral session asks how you would advise an undervalued CEO, expecting a structured multi-layer response covering validation, data-driven analysis of the valuation gap, and specific action steps like buybacks, investor relations campaigns, operational improvements, or potential spin-offs. This reflects Lazard's identity as a trusted CEO advisor.
What Makes Lazard Interviews Unique
EBITDA Multiple Consistency and Gordon Growth Application
The technical session tests whether you understand that the numerator of a multiple must match the denominator's claim on cash flows, and applies the Gordon Growth Model to valuing an apple tree rather than a stock. Lazard uses these conceptual questions to assess whether your understanding of valuation is principled rather than formula-driven.
Mezzanine Debt Rationale and Capital Structure Nuance
A distinctive technical question asks why companies use mezzanine debt, expecting you to discuss flexibility, PIK interest options, looser covenants, and the gap it fills between senior debt capacity and total funding needs. This reflects Lazard's restructuring expertise and deep understanding of complex capital structures.
Independent Advisory Model Woven Into Behavioral Questions
The behavioral session asks about a CEO's vulnerability and a banker's duty, directly connecting to Lazard's position as an independent advisory firm without lending or underwriting conflicts. Prepare to discuss how independent advice creates deeper client trust and how Lazard's structure allows bankers to give unconflicted counsel.
Integrity and Ethics as Core Behavioral Themes
Multiple behavioral questions probe integrity, including describing a role model known for ethical behavior, a specific instance where you acted with integrity at personal cost, and your favorite class being connected to ethics. Lazard places exceptional weight on character and expects candidates to demonstrate that ethical reasoning is embedded in their decision-making process.

About This Lazard Mock Interview
These sessions simulate Lazard's interview approach across technical and behavioral formats. The technical session covers cash EPS versus GAAP EPS, 10-K navigation for shares outstanding, EBITDA multiple consistency principles, Gordon Growth Model application, brain teasers including the painted cube problem, WACC U-shape curve, quantitative multi-step problems deriving debt, equity, market cap, and enterprise value from ratios, LBO leverage determination rules, IRR rules of thumb, bond YTM approximation, bank valuation methods, warranty expense walkthroughs, and mezzanine debt rationale. The behavioral session tests analytical rigor through NPV-based decision examples, integrity and ethics scenarios, leadership evolution, CEO advisory frameworks, and Lazard-specific fit.

The IB Vine technical prep is beyond helpful, it's so much more fun quizzing myself every now and then vs. reading through the guides again.

Check out IB Vine, specifically the 'IB Vine Select' questions. Once you can get a handle of those, it seems like you are in a spot where you're applying the concepts rather than simply memorizing them

IB Vine has excellent questions, especially multistep ones. In my experience I've gotten grilled on accretion/dilution, bond math, and merger model questions. IB Vine has great practice for all of those.

As a nontraditional transfer student who has been rendered unavailable to many resources at my university (Leadership positions at clubs, immediately behind the recruiting cycle, etc.) IB Vine has been an absolute game changer in my IB prep.

From my experience interviewing FT for IB, it’s not enough to just know the 400 questions anymore (it’s a good starting point) but to look at even more advanced questions. Would recommend IB Vine.

Just got off the phone with a kid who interned at a Dallas PE firm. He mentioned that IB Vine helped him secure that internship as well as his Summer Analyst offer, especially since he came from a non-target with no resources.
