Investment Banking Interview Guide — DCF, LBO, and Market Sizing for Indian Finance Aspirants

Investment Banking in India: The Opportunity and the Bar

India’s investment banking sector has seen explosive growth, with deal volumes hitting a record $92 billion in M&A activity in 2024 (Bloomberg). Firms like Goldman Sachs, JP Morgan, Morgan Stanley, Kotak, Axis Capital, ICICI Securities, and Jefferies India are competing fiercely — and hiring rigorously.

An IB interview in India is one of the most technically demanding hiring processes in any domain. It tests financial modelling, valuation theory, market awareness, and the personal resilience to handle 80-100 hour work weeks. This guide covers the core technical and non-technical elements you must master.

The 4-Round IB Interview Structure (Typical at Bulge Brackets in India)

The 3 Valuation Methods — Must Know Cold

Method 1: DCF (Discounted Cash Flow)

CONCEPT:

A company is worth the present value of all its future free cash flows, 

discounted at its Weighted Average Cost of Capital (WACC).

KEY FORMULA:

Enterprise Value = Σ [FCF_t / (1+WACC)^t] + [Terminal Value / (1+WACC)^n]

COMMON DCF INTERVIEW QUESTIONS:

→ “Walk me through a DCF.”

→ “What happens to a company’s value if WACC increases?”

→ “How do you calculate terminal value?” 

   (Gordon Growth Model: TV = FCF × (1+g) / (WACC – g)

   or Exit Multiple Method: TV = EBITDA × Multiple)

→ “Why might a DCF be misleading?”

   (Highly sensitive to WACC and terminal value assumptions)

Method 2: Comparable Company Analysis (Public Comps)

CONCEPT:

Value a company by comparing it to similar publicly traded companies 

using valuation multiples.

KEY MULTIPLES (India context):

→ EV/EBITDA (most common — enterprise value to EBITDA)

→ P/E (Price to Earnings — used in financial services)

→ EV/Revenue (used for early-stage or high-growth companies)

→ P/B (Price to Book — used in banking sector)

COMMON QUESTIONS:

→ “Why use EV/EBITDA over P/E?”

   (EV/EBITDA is capital structure-neutral; P/E is affected by leverage)

→ “How do you select comparable companies?”

   (Similar size, business model, geography, growth profile, margins)

Method 3: Precedent Transactions (Deal Comps)

CONCEPT:

Value a company based on multiples paid in similar M&A transactions.

KEY INSIGHT FOR INDIA:

Precedent transaction multiples are typically HIGHER than public 

comps because of the control premium paid in acquisitions 

(typically 20–30% premium over market price in Indian M&A).

COMMON QUESTION:

→ “Why are precedent transaction multiples higher than trading comps?”

   → Control premium + synergies baked into deal price

LBO (Leveraged Buyout) — The Most Feared Question

CONCEPT:

A PE firm acquires a company using mostly debt (leverage), 

improves operations, then sells it at a higher multiple or via IPO.

KEY LBO METRICS:

→ Entry multiple vs. Exit multiple

→ IRR (Internal Rate of Return) — target: 20–30% for PE

→ MOIC (Multiple on Invested Capital) — target: 2–3x in 5 years

→ Debt paydown schedule

CLASSIC QUESTION: “What makes a good LBO candidate?”

ANSWER:

→ Stable, predictable free cash flows (to service debt)

→ Low capital expenditure requirements

→ Strong market position

→ Potential for operational improvement

→ Reasonable entry valuation

→ Clear exit path (strategic buyer, IPO)
