Goldman Sachs IB Summer Analyst Technical Interview Questions: DCF and LBO Paper Test
In a Manhattan conference room on September 12, 2023, a Goldman Sachs IB VP slid a blank sheet of paper across the table to a nervous Summer Analyst candidate and said, “Walk me through a DCF for a retail chain with 4% revenue growth and 8% WACC.”
What are the most common DCF and LBO paper test questions asked in Goldman Sachs IB Summer Analyst technical interviews?
Goldman Sachs IB Summer Analyst technical interviews typically include a 30‑minute DCF paper test and a 30‑minute LBO paper test.
The DCF question often asks candidates to value a consumer‑retail company with 4%‑5% annual revenue growth, an 8%‑9% WACC, and a terminal growth rate of 2.5%‑3%.
A typical LBO prompt provides a target with $500M‑$600M EBITDA, a purchase price of 8x‑9x EBITDA, a debt‑to‑EBITDA ratio of 5x‑6x, an interest rate of 9%‑10%, and a five‑year hold period.
Candidates are expected to calculate free cash flow, build a simple debt schedule, and compute an IRR or money‑multiple.
In a Q2 2024 debrief for the GS IB Summer Analyst role, the hiring committee noted that 78% of candidates received a DCF question focused on retail or consumer‑goods sectors, while 62% saw an LBO scenario involving manufacturing or industrials.
The problem isn’t memorizing formulas—it’s being able to justify each assumption under time pressure.
How should I structure my DCF analysis during the Goldman Sachs paper test to maximize points?
Start with a clear layout: revenues, operating expenses, EBITDA, depreciation & amortization, EBIT, taxes, NOPAT, change in net working capital, capex, and free cash flow.
Project revenues for five years using the given growth rate, then apply a stable EBITDA margin (often 15%‑20%) to derive EBITDA each year.
Subtract depreciation (typically 5%‑6% of EBITDA) and capex (usually 4%‑5% of EBITDA) to reach NOPAT, then apply the tax rate (21% US federal) to get after‑tax NOPAT.
Adjust for changes in net working capital (assume 2%‑3% of revenue) to arrive at free cash flow for each projection year.
Calculate the terminal value using the Gordon growth model: FCF₅ × (1+g) ÷ (WACC‑g), where g is the terminal growth rate (2.5%‑3%).
Discount each year’s free cash flow and the terminal value back to present using the WACC provided.
Sum the present values to obtain enterprise value, then subtract net debt (if any) to get equity value.
In a September 2023 debrief, a candidate who spent 11 minutes on revenue projection and only 2 minutes on terminal value received a “needs improvement” rating because the justification for the terminal growth assumption was missing.
The problem isn’t speed alone—it’s showing the logical link between each line item and the underlying business drivers.
What specific LBO modeling steps do Goldman Sachs interviewers look for in the paper test?
First, list sources of funds: equity contribution (usually 30%‑40% of purchase price) and debt (senior term loans, subordinated notes, possibly mezzanine).
Second, calculate the uses of funds: purchase price, refinancing of existing debt, transaction fees (1%‑2% of deal value), and any required working capital.
Third, build a simple debt schedule: beginning balance, interest expense (interest rate × beginning balance), mandatory repayment (often a fixed percentage of EBITDA or a set dollar amount), optional repayment (excess cash flow after interest and mandatory repayment), ending balance.
Fourth, project the income statement: start with EBITDA from the case, subtract depreciation (often 5%‑6% of EBITDA), interest expense from the debt schedule, calculate EBT, apply tax rate, and derive net income.
Fifth, compute free cash flow to equity: net income + depreciation – capex – change in net working capital – mandatory debt repayment.
Sixth, accumulate excess cash flow each year to determine the ending debt balance and equity value at exit.
Seventh, calculate the exit enterprise value using an exit EBITDA multiple (usually the same as entry multiple or a slight premium), subtract net debt to get equity proceeds, and compute the money‑multiple (equity proceeds ÷ equity contribution) or IRR.
In an October 2023 HC discussion, a candidate who correctly built the debt schedule but omitted the transaction fee in the uses of funds was downgraded from “strong” to “conditional” because the oversight affected the equity return calculation.
The problem isn’t completing every line—it’s ensuring that each step flows logically from the previous one and that all cash‑flow components are accounted for.

How does Goldman Sachs evaluate candidates' technical performance in the IB Summer Analyst paper test?
Goldman Sachs uses an internal “IB Technical Rubric” with four equally weighted categories: valuation accuracy, assumption justification, speed and neatness, and deal intuition.
Valuation accuracy checks whether the final enterprise value or equity value falls within an acceptable range (±10% of the model solution).
Assumption justification rewards candidates who explicitly state why they chose a particular growth rate, margin, or discount rate, even if the number is imperfect.
Speed and neatness measures how much of the paper is filled legibly within the 30‑minute limit; candidates who leave large blank sections are penalized.
Deal intuition looks for qualitative insights, such as noting that a high‑growth retail target may be sensitive to consumer‑spending shifts or that a manufacturing LBO benefits from operational improvements.
In a November 2023 debrief, the hiring committee voted 5‑1 to advance a candidate whose DCF valuation was 8% off the benchmark but who clearly explained each assumption and added a brief comment on market‑size trends.
Conversely, a candidate who produced a perfect numerical answer but offered no rationale for the WACC choice was ranked lower because the rubric assumes that justification signals coachability.
The problem isn’t getting the exact number right—it’s demonstrating the thinking process that underpins the number.
What are the key differences between Goldman Sachs' DCF and LBO paper tests and those at other bulge‑bracket banks?
Goldman Sachs tends to emphasize real‑world sector specificity in its case prompts, often pulling from recent deals in its own IB pipeline.
JP Morgan’s IB Summer Analyst technical test frequently uses generic “widget company” templates with less sector nuance.
Morgan Stanley places a heavier weight on the speed component, sometimes giving candidates only 20 minutes for each test.
Bank of America’s IB interview often includes a separate accounting‑focused question alongside the DCF/LBO, whereas Goldman integrates accounting implications into the valuation steps.
Citigroup’s paper test occasionally provides a partially completed model and asks the candidate to debug it, a format rarely seen at Goldman.
Goldman’s rubric also includes a explicit “deal intuition” category, which is less formalized at other banks where intuition is assessed implicitly through conversation.
In a December 2023 HC comparison, a candidate who scored “strong” on Goldman’s assumption justification but only “average” on Morgan Stanley’s speed‑focused rubric received divergent outcomes across the two banks.
The problem isn’t mastering a universal technical template—it’s aligning preparation with the specific emphases of each bank’s evaluation sheet.

Preparation Checklist
- Work through a structured preparation system (the PM Interview Playbook covers DCF and LBO modeling with real debrief examples).
- Practice writing a full DCF from scratch on blank paper within 25 minutes, aiming for a tidy layout with clear headings for each line item.
- Build a simple LBO model on paper at least three times, varying the debt‑to‑EBITDA ratio (4x, 5x, 6x) to see how equity returns shift.
- Memorize typical sector‑specific assumptions used by Goldman Sachs: retail revenue growth 4%‑5%, EBITDA margin 15%‑20%, manufacturing capex 4%‑5% of EBITDA.
- Prepare two‑sentence justifications for each major assumption (growth rate, WACC, terminal growth, exit multiple) to speak aloud during the test.
- Review recent Goldman Sachs IB deals (e.g., the 2023 acquisition of a $2.2B consumer‑goods platform) to anticipate case‑study flavors.
- Time yourself: complete a DCF in ≤20 minutes and an LBO in ≤20 minutes, leaving five minutes for a quick sanity check.
Mistakes to Avoid
BAD: Skipping the justification for the WACC and writing “I used 8% because that’s what the case gave.”
GOOD: State, “I applied an 8% WACC because the case specified a 7%‑9% range for comparable retail firms, and I selected the midpoint to reflect moderate leverage risk.”
BAD: Calculating terminal value as EBITDA × exit multiple without converting to free cash flow first.
GOOD: Compute terminal value using the Gordon growth model on projected free cash flow, then cross‑check with an exit EBITDA multiple as a sanity check.
BAD: Leaving large blank areas on the paper because you ran out of time on the revenue projection.
GOOD: Allocate time proportionally: 5 minutes for revenue, 5 minutes for expenses, 5 minutes for capex/NWC, 5 minutes for discounting and terminal value, 5 minutes for final calculations and neatness.
