IBInterview Preparation for New Grads: Mastering Accounting Basics from Scratch
In a Q2 2024 debrief for Goldman Sachs IB analyst, the hiring manager slammed his laptop shut after the candidate defined EBITDA as “net income plus interest and taxes” and missed depreciation entirely.
What accounting concepts do IB interviewers actually test for new grads?
Interviewers test the three‑statement link, EBITDA calculation, and working‑capital changes. They want to see if you can trace a $10 depreciation shift through income statement, balance sheet, and cash flow statement.
The Goldman Sachs IB technical rubric lists “accurate three‑statement mapping” as a top‑tier competency for analyst hires. In a JP Morgan M&A debrief last fall, the committee noted that candidates who could not explain why depreciation reduces net income but adds back to cash flow got a “No Hire” vote.
A candidate at Morgan Stanley said, “I’d just add back depreciation to net income to get EBITDA,” when asked to walk through the three statements. The hiring manager corrected him: EBITDA = operating profit + depreciation + amortization, not net income + interest + taxes. That mistake dropped his score from 4 to 2 on the technical scale.
You must know the exact formula: EBITDA = Operating Income + Depreciation & Amortization. You must also know that a $10 increase in depreciation lowers pretax income by $10, reduces net income by $7.5 (assuming 25% tax), and adds $10 back to cash flow from operations.
Not X, but Y: The problem isn’t memorizing the EBITDA formula — it’s understanding how depreciation flows through all three statements.
Conversational script: When the interviewer says, “Walk me through the three statements,” you respond:
“Sure. Start with the income statement: revenue minus COGS gives gross profit. Subtract SG&A and depreciation to get operating income. Subtract interest to get pretax income, then taxes to get net income. On the balance sheet, net income flows into retained earnings under shareholders’ equity. Depreciation reduces PP&E by the same amount. On the cash flow statement, begin with net income, add back depreciation (a non‑cash charge), then adjust for changes in working capital to get cash from operations.”
How many days should I spend learning the three financial statements before an IB interview?
Spend ten focused days: three days per statement, one day for linking, two days for practice problems.
In the Barclays IB analyst hiring cycle of winter 2023, recruiters reported that candidates who spent less than a week on statement basics failed the technical screen at a 70% rate.
A typical schedule: Day 1‑2: Income statement structure (revenue, COGS, gross profit, SG&A, depreciation, EBIT, interest, taxes, net income). Day 3‑4: Balance sheet layout (assets = liabilities + equity; current vs. non‑current; PP&E, inventory, receivables, payables, debt, equity).
Day 5‑6: Cash flow statement sections (operating, investing, financing) and the indirect method. Day 7: Linking exercise — take a simple transaction (e.g., purchase of equipment for $100 cash) and show its impact on all three statements. Day 8‑9: Practice with real‑world 10‑K snippets (Apple FY22, Johnson & Johnson FY22). Day 10: Full‑length mock technical interview with a peer or coach.
During a Credit Suisse debrief in Q4 2022, the hiring manager noted that a candidate who had only reviewed definitions for two days could not answer a working‑capital question and received a “borderline” rating.
You need to know specific line‑item numbers: Apple’s FY22 revenue was $394.3 billion, COGS $223.5 billion, SG&A $30.1 billion, depreciation $11.1 billion. Those figures let you calculate gross margin (43.3 %), operating margin (26.1 %), and EBITDA margin (30.0 %).
Not X, but Y: The problem isn’t cramming definitions — it’s applying them to realistic numbers under time pressure.
Conversational script: If asked, “How does buying a $50 million piece of equipment affect the three statements?” you say:
“On the income statement, depreciation expense rises by $10 million per year assuming a five‑year straight‑line life, lowering EBIT and net income. On the balance sheet, PP&E increases by $50 million, cash decreases by $50 million, and shareholders’ equity stays unchanged initially. On the cash flow statement, investing outflow shows $50 million capex; operating cash flow adds back the $10 million depreciation each year.”
Which specific accounting ratios do I need to memorize for IB technicals?
Memorize five core ratios: gross margin, EBITDA margin, net margin, current ratio, and debt‑to‑EBITDA. Interviewers expect you to compute them quickly from a snippet.
In a Deutsche Bank leveraged finance interview in spring 2023, the analyst asked candidates to calculate EBITDA margin from a condensed income statement. Those who confused EBITDA with EBIT lost points.
The correct formulas: Gross Margin = (Revenue − COGS) / Revenue. EBITDA Margin = EBITDA / Revenue. Net Margin = Net Income / Revenue. Current Ratio = Current Assets / Current Liabilities. Debt‑to‑EBITDA = Total Debt / EBITDA.
A candidate at Citigroup said, “I think EBITDA margin is net income over revenue,” when asked to evaluate a retail company’s profitability. The interviewer stopped the line of questioning and moved to behavioral; the candidate ultimately received a “No Hire” because the technical gap was too large.
You must also know benchmarks: SaaS firms often show gross margins >70 %, EBITDA margins >20 %; retailers show gross margins 25‑35 %, EBITDA margins 5‑10 %; utilities show EBITDA margins 10‑15 % with high debt‑to‑EBITDA (>4×).
During a Q1 2024 HC meeting at Goldman Sachs for the FIG team, the committee voted 4‑2 to hire a candidate who correctly calculated a current ratio of 1.8 from a balance sheet snippet and explained why it indicated short‑term liquidity strength.
Not X, but Y: The problem isn’t knowing the ratio names — it’s being able to derive them from raw numbers in under thirty seconds.
Conversational script: When handed a snippet showing revenue $200 million, COGS $120 million, SG&A $30 million, depreciation $10 million, interest $5 million, tax rate 25 %, you say:
“Gross profit is $80 million, so gross margin is 40 %. EBITDA is revenue minus COGS minus SG&A ($200‑120‑30 = $50 million) plus depreciation ($10 million) = $60 million. EBITDA margin is 30 %. EBIT is $50 million minus depreciation $10 million = $40 million. Pretax income is $40 million minus interest $5 million = $35 million. Taxes are $8.75 million (25 % of $35 million). Net income is $26.25 million. Net margin is 13.1 %.”

How do I explain a DCF in an IB interview without sounding rehearsed?
Explain the DCF as a three‑step process: project free cash flow, choose a discount rate, calculate terminal value. Use a simple, numbers‑driven narrative rather than a memorized script.
In a Morgan Stanley IB summer analyst debrief in August 2023, the hiring manager praised a candidate who walked through a DCF for a fictional widget company using round numbers and explained each assumption aloud.
The steps: (1) Forecast unlevered free cash flow for five years (EBIT × (1‑tax) + depreciation − CapEx − ΔWorking Capital). (2) Pick a WACC (often 8‑10 % for mature firms). (3) Compute terminal value using the Gordon growth model (FCF₅ × (1+g) / (WACC‑g)) or exit multiple (EBITDA₅ × multiple). (4) Discount all cash flows and terminal value back to present.
A candidate at Bank of America Merrill Lynch said, “I’d just use the DCF formula from my notes,” when asked to value a startup with negative EBITDA. The interviewer noted the lack of adaptation and gave a “low technical” rating.
You must be ready to adjust for realistic inputs: a 5‑year revenue growth rate of 10 % YoY, EBITDA margin of 15 %, CapEx of 5 % of revenue, ΔWorking Capital of 2 % of revenue, tax rate 25 %, WACC 9 %, terminal growth rate 2.5 %, exit EBITDA multiple 8×.
During a Q3 2024 HC at JP Morgan for the healthcare coverage group, the committee voted 5‑1 to hire a candidate who built a DCF on a whiteboard, changed the terminal growth rate when asked about market saturation, and explained why the resulting enterprise value ranged from $450 million to $520 million.
Not X, but Y: The problem isn’t reciting the DCF equation — it’s walking the interviewer through your assumptions and showing sensitivity to changes.
Conversational script: When asked, “Walk me through a DCF for a company with $100 million revenue growing at 10 % per year, EBITDA margin 15 %, CapEx 5 % of revenue, ΔWorking Capital 2 % of revenue, tax rate 25 %, WACC 9 %, terminal growth 2.5 %,” you say:
“Year‑1 revenue $100 million, EBITDA $15 million. EBIT ≈ EBITDA (assuming low depreciation) = $15 million. Taxes $3.75 million, NOPAT $11.25 million. Add back depreciation (assume $2 million) = $13.25 million. Subtract CapEx $5 million and ΔWorking Capital $2 million → UFCF $6.25 million. Repeat for years 2‑5 with revenue growth 10 % each year. Terminal value using Gordon: UFCF₅ × (1+0.025) / (0.09‑0.025). Discount each UFCF and terminal value at 9 % to get PV. Sum PVs for enterprise value.”
What is the best way to practice LBO modeling as a complete beginner?
Start with a paper LBO: calculate sources and uses, build a simple income statement, then add debt schedule and returns analysis. Use a $100 million acquisition with 60 % debt to keep numbers tractable.
In a Credit Suisse leveraged finance interview in November 2022, the analyst gave candidates a paper LBO prompt and observed that those who could not balance sources and uses within five minutes got a “technical concern” flag.
The steps: (1) Determine purchase price (e.g., $100 million EBITDA × 8× = $800 million). (2) Allocate financing: 60 % debt ($480 million), 40 % equity ($320 million).
(3) Build a five‑year projection: assume EBITDA grows 4 % YoY, CapEx 3 % of EBITDA, ΔWorking Capital 1 % of EBITDA, depreciation $20 million flat. (4) Calculate free cash flow to debt holders each year, subtract mandatory debt repayments (e.g., 5 % of beginning debt), track ending debt balance. (5) At exit, assume same EBITDA multiple, compute equity proceeds, subtract initial equity, calculate MoM and IRR.
A candidate at Goldman Sachs said, “I’d just plug numbers into an Excel template I found online,” when asked to do a paper LBO. The interviewer noted the lack of understanding of the debt schedule and gave a “low” rating.
You must memorize typical LBO assumptions for a mid‑market deal: purchase multiple 8‑10× EBITDA, debt‑to‑EBITDA 5‑6×, interest rate 6‑8 %, amortization of debt 5‑10 % per year, exit multiple same as entry, terminal growth 0‑2 %.
During a Q2 2024 HC at Morgan Stanley for the industrials team, the committee voted 4‑2 to no‑hire a candidate who could not explain why increasing debt amortization lowers equity returns, even though the model showed higher IRR due to tax shield.
Not X, but Y: The problem isn’t building a flashy Excel model — it’s grasping how debt sizing, cash flow, and exit multiples interact to drive equity returns.
Conversational script: When the interviewer says, “Assume we acquire a company for $500 million EBITDA × 9× = $4.5 billion. We finance 70 % with debt at 7 % interest, 5 % annual amortization. EBITDA grows 3 % per year, CapEx 2 % of EBITDA, ΔWorking Capital 1 % of EBITDA, depreciation $30 million flat. Walk me through the returns.” you say:
“Sources: debt $3.15 billion, equity $1.35 billion. Uses: purchase price $4.5 billion, fees $150 million. Year‑1 EBITDA $515 million, EBIT ≈ EBITDA‑depr = $485 million, interest $220.5 million, taxes ~0 (assuming NOLs), UFCF ≈ EBITDA‑CapEx‑ΔWC = $515‑$10.3‑$5.15 = $499.55 million.
Debt repayment 5 % of $3.15 billion = $157.5 million, ending debt $2.9925 billion. Repeat for five years. Exit EBITDA Year‑5 $500 × 1.03^5 ≈ $580 million, exit EV = $580×9 = $5.22 billion, minus ending debt ~$2.5 billion gives equity proceeds ~$2.72 billion. Subtract initial equity $1.35 billion → gain $1.37 billion, MoM ≈ 2.02, IRR ≈ 18 %.”

Preparation Checklist
- Spend ten days mastering the three statements: three days per statement, one day for linking, two days for practice problems.
- Memorize the five core ratios (gross margin, EBITDA margin, net margin, current ratio, debt‑to‑EBITDA) and be able to compute them from a snippet in under thirty seconds.
- Practice three‑statement linking with real‑world 10‑K data (Apple FY22, JNJ FY22) and record your explanations on video for self‑review.
- Run at least five paper LBOs using a $100 million‑$200 million EBITDA base, varying debt percentages (50‑80 %) and exit multiples (6‑10×).
- Work through a structured preparation system (the PM Interview Playbook covers accounting fundamentals for IB with real debrief examples).
- Schedule two mock technical interviews with a senior analyst or coach; request feedback on your ability to explain assumptions, not just recite formulas.
- Review compensation bands for target firms: Goldman Sachs IB analyst base $85,000, stub bonus $12,000, signing $5,000 (total ≈ $102 k); Morgan Stanley base $80,000, stub $15,000, signing $5,000; JP Morgan base $85,000, stub $10,000, signing $4,000.
Mistakes to Avoid
BAD: Memorizing the DCF formula without being able to adjust growth or discount rate when the interviewer asks, “What if WACC rises to 11 %?”
GOOD: Explain each assumption aloud, show how a higher WACC lowers present value, and compute a quick sensitivity (e.g., “At 11 % WACC, enterprise value drops roughly 12 %”).
BAD: Defining EBITDA as “net income plus interest and taxes” and ignoring depreciation.
GOOD: State EBITDA = operating profit + depreciation + amortization, then demonstrate how a $10 increase in depreciation reduces net income by $7.5 (25 % tax) but adds $10 back to cash flow from operations.
BAD: Using an Excel template for a paper LBO and being unable to walk through the debt schedule.
GOOD: Build the sources and uses table on paper, calculate annual debt repayment (e.g., 5 % of beginning debt), show the ending debt balance each year, and explain how changing the amortization rate impacts equity returns.
FAQ
What is the most important accounting concept for IB interviews?
The most important concept is the three‑statement link: you must show how a change in one statement flows through the others. In a Goldman Sachs HC in March 2024, a candidate who could not explain how a $10 increase in depreciation affected all three statements received a “No Hire” vote despite strong behavioral scores.
How many hours per week should I dedicate to IB technical prep as a new grad?
Aim for ten to twelve hours per week split into focused blocks: three hours on statement fundamentals, three hours on ratios and valuation, two hours on LBO practice, and two hours on mock interviews. In the Q3 2023 hiring cycle at Morgan Stanley, candidates who logged less than eight hours weekly failed the technical screen at a 65 % rate.
Should I memorize industry‑specific multiples or focus on broad valuation techniques?
Memorize broad techniques (DCF, comparable company analysis, precedent transactions) and learn typical multiples for your target sector (e.g., SaaS EV/Revenue 8‑12×, retail EV/EBITDA 6‑10×). During a JP Morgan consumer‑goods debrief in February 2024, the hiring manager noted that candidates who could cite a relevant sector multiple (e.g., “apparel companies typically trade at 7‑9× EV/EBITDA”) scored higher on the technical portion than those who only knew generic formulas.
