Technical Phone Screen - Financial Modeling and Excel

60 min4 focus topicstechnical

What to Expect

A 60-minute technical assessment via phone or video where you demonstrate financial modeling and Excel proficiency. You may receive a simplified financial case study or dataset and be asked to create a basic financial model, calculate key metrics, or analyze financial trends. The interviewer assesses your ability to structure problems, use Excel functions and formulas, and articulate your approach. You may work in a shared screen environment like Google Sheets or be asked to narrate your thinking while solving problems.

Tips & Advice

Practice building simple financial models from scratch covering revenue projections, expense analysis, and variance calculations. Master core Excel functions: SUMIF, VLOOKUP, INDEX-MATCH, PivotTables, and basic formulas. Clearly explain your assumptions and logic before diving into calculations. For entry-level, interviewers expect foundational competency, not advanced techniques, but precision and clarity matter. Talk through your approach: 'I'm breaking this into revenue and cost projections, then I'll calculate the difference and year-over-year growth.' Organize your spreadsheet logically with clear headers, separated inputs from calculations, and clean formatting. Practice speaking clearly about what you're doing rather than silently working.

Focus Topics

Basic Financial Modeling

Constructing simple multi-period financial models with revenue assumptions, cost projections, and profit/loss outcomes; understanding drivers and sensitivities

Problem Decomposition and Communication

Breaking financial problems into components, defining assumptions clearly, explaining calculations aloud, and presenting results in a logical narrative

Financial Metrics and Calculations

Understanding and calculating key metrics: revenue growth, margins (gross, operating, net), variance (actual vs. budget), year-over-year and month-over-month growth, and basic cash flow concepts

Excel Fundamentals for Financial Analysis

Proficiency with formulas (SUM, SUMIF, VLOOKUP, INDEX-MATCH), PivotTables, absolute vs. relative references, data validation, and spreadsheet organization for financial models

Technical Phone Screen - SQL and Data Analysis

60 min4 focus topicstechnical

What to Expect

A 60-minute technical assessment where you solve SQL queries or data analysis problems using a coding platform or spreadsheet. You may be given a business scenario (e.g., 'Analyze subscriber churn by region') and asked to retrieve, transform, and analyze data using SQL or Python/Pandas. The focus is on your ability to write clean, correct queries, understand data structures, and extract meaningful insights. You'll be evaluated on query logic, performance awareness, and ability to explain your approach.

Tips & Advice

Practice writing clean SQL queries using SELECT, WHERE, JOIN, GROUP BY, HAVING, and ORDER BY clauses. For entry-level, focus on correctness and clarity over optimization. Understand different join types and when to use them. Practice reading and interpreting data schemas. If using Python/Pandas, be comfortable with filtering, grouping, aggregating, and reshaping data. Approach each query methodically: clarify what you're trying to find, outline the steps, then write the query. Test edge cases. Explain your logic: 'I'm joining the subscriber table to the activity table to link subscribers with their engagement, then grouping by region to compare churn rates.' For entry-level, interviewers expect solid fundamentals, not expert optimization.

Focus Topics

Python/Pandas for Data Manipulation (if applicable)

If the role emphasizes Python: filtering, grouping, aggregating, and reshaping data using Pandas; creating simple visualizations; understanding when to use Python vs. SQL

Data Interpretation and Insight Generation

Reading query results, identifying patterns, spotting anomalies, and articulating what the data reveals about the business (e.g., 'This shows churn is 15% higher in Region B, potentially driven by lower customer engagement')

Data Aggregation and Analysis

Using aggregate functions (COUNT, SUM, AVG, MIN, MAX), calculating cohort metrics, period-over-period comparisons, and summarizing data by business dimensions (region, product, customer segment)

SQL Query Writing - Core Concepts

Writing correct SELECT statements, filtering with WHERE, joining multiple tables (INNER, LEFT, RIGHT), grouping and aggregating with GROUP BY, filtering aggregates with HAVING, and sorting with ORDER BY

Business Case Study - Financial Analysis

75 min5 focus topicscase study

What to Expect

A 75-minute interview combining a realistic business problem with financial analysis. You'll be presented with a scenario (e.g., 'Netflix is considering expanding into a new market; analyze the financial viability') and given partial data or asked to outline your approach. You may receive financial statements, subscriber data, or cost information and be asked to evaluate performance, forecast outcomes, identify cost-saving opportunities, or recommend a strategic decision. This round assesses your ability to apply analytical skills to ambiguous, real-world problems while communicating clearly.

Tips & Advice

Use a structured problem-solving framework: deconstruct the scenario, clarify success metrics, outline your analytical approach, perform calculations or build a simple model, and present clear recommendations backed by data. For entry-level, interviewers expect logical thinking and solid execution, not perfect answers. Speak your assumptions aloud: 'I'm assuming subscriber acquisition cost is $50 per user based on industry benchmarks.' Ask clarifying questions when information is ambiguous. Practice on business case examples and real Netflix scenarios (e.g., analyzing profitability by market, evaluating content investment ROI, or forecasting subscription growth). Structure your output clearly with problem statement, key drivers, calculations, findings, and recommendations. Practice communicating uncertainty appropriately: 'Based on available data, we can reasonably project...' rather than overconfident claims.

Focus Topics

Netflix Business Context

Understanding Netflix's revenue model (subscription-based, advertising), key cost drivers (content, infrastructure, marketing), competitive pressures (market saturation, password sharing policies), and growth opportunities (new markets, product tiers)

Business Case and Investment Evaluation

Evaluating opportunities using financial metrics: ROI, payback period, net present value concepts, break-even analysis, and return on investment in the context of business strategy

Financial Storytelling and Communication

Presenting findings in a clear narrative with visuals (simple charts, summary tables), explaining the 'so what' of results, and tailoring communication to audience (business stakeholders vs. finance teams)

Financial Forecasting and Modeling Under Uncertainty

Creating reasonable projections with stated assumptions, sensitivity analysis basics, understanding confidence intervals, and communicating uncertainty appropriately

Financial Problem Decomposition

Breaking down business scenarios into financial components, identifying key drivers (revenue, costs, margins), defining success metrics, and structuring an analytical approach

Behavioral and Culture Fit Interview

50 min6 focus topicsbehavioral

What to Expect

A 45-60 minute interview with a hiring manager or senior team member focused on assessing cultural fit, collaboration, learning ability, and professional maturity. You'll be asked about past experiences, how you've handled challenges, worked with others, responded to feedback, and contributed to teams. Questions explore your problem-solving approach, adaptability, communication style, and alignment with Netflix values (freedom, responsibility, innovation, impact). The interviewer evaluates whether you can work independently while seeking help when needed, take ownership of tasks, learn from mistakes, and collaborate effectively.

Tips & Advice

Prepare STAR stories (Situation, Task, Action, Result) for common scenarios: solving a problem with limited information, collaborating with teammates, receiving critical feedback, handling a mistake, and achieving a goal. For entry-level, focus on learning mindset, initiative, and coachability. Be authentic and reflective; acknowledge what you learned from challenges rather than claiming perfection. Netflix values independent thinking and ownership, so highlight examples where you took initiative or made a decision independently (with appropriate scope for entry-level). Practice discussing failures or mistakes constructively: 'I misunderstood the requirements initially, but I asked clarifying questions and adjusted my approach.' Be specific rather than generic; use concrete examples from projects, internships, or academic work. Ask thoughtful questions about team culture, growth opportunities, and what success looks like in the first year.

Focus Topics

Adaptability and Handling Ambiguity

Responding positively to changing requirements, navigating unclear situations, adjusting strategies when needed, and staying composed under pressure

You must present to the board to defend a proposed 20% increase in global content spend. Prepare the financial and strategic case you would present: estimated incremental subscribers and ARPU uplift, projected payback period and NPV, sensitivity to hit-rate and retention, impact on EBITDA and free cash flow, and recommended gating criteria and monitoring KPIs to control execution risk.

Sample Answer

**Executive summary (ask)** I recommend a 20% increase in global content spend (+$400M on top of $2.0B baseline) to accelerate lineup quality, reduce churn in priority markets, and unlock new subscribers. Below is the concise financial + strategic case, sensitivities, and execution controls.

**Base-case financial assumptions** - Current subs: 50.0M; ARPU: $8.00/month; annual content spend: $2.0B. - Incremental content spend: +$400M (one-time annual run-rate). - Expected outcomes (12–24 months): incremental subscribers = 5% lift → +2.5M subs; ARPU uplift = +3% → +$0.24/mo. Churn improvement = -0.5 ppts annually.

**Projected impact (annual run-rate)** - Incremental revenue from subs: 2.5M * $8.24 * 12 = $247.2M. - Revenue uplift from ARPU on existing base: 50M * $0.24 * 12 = $144M. - Total incremental revenue ≈ $391.2M. - EBITDA impact (assume 25% incremental margin): +$97.8M; incremental cash flow before capex ≈ $97.8M. - Payback period on incremental spend: $400M / $97.8M ≈ 4.1 years. - NPV (discount 10%, perpetual benefit simplified to Year1 FCF growing 2%): using a conservative perpetuity = FCF /(r - g) = 97.8 / (0.10-0.02) = $1,222.5M → NPV of incremental spend ≈ $822.5M (less $400M upfront) = +$422.5M. (Run full model for staged benefit timing.)

**Sensitivity analysis (key levers)** - Hit-rate (subs uplift): ±50% change in incremental subs → payback swings 2.6–8.3 yrs. - Retention: each -0.1ppt churn improvement ≈ +$20–25M EBITDA. - ARPU variance ±1ppt → ±$60M revenue. Recommend tornado chart in appendix.

**Strategic rationale** - Strengthens content moat in high-growth markets, supports longer-term ARPU segmentation, and reduces acquisition pressure. - Non-financial: brand halo, partner leverage, rights ownership benefits.

**Impact on EBITDA & FCF (summary)** - Short-term EBITDA hit net of incremental revenue and marketing could compress margins ~150–300bps in worst-case first year; by year 2–3 expect margin recovery and FCF accretion as benefits scale.

**Gating criteria & monitoring KPIs** - Gating (go/no-go checkpoints, quarterly): 1. Q1: Pilot markets (top 5) show >=2% QoQ net subscriber lift attributed to new content and ARPU lift >=1%. 2. Q2: Churn delta vs control >=0.25ppt improvement and engagement (watch-hours) +10%. 3. Q4: Cumulative incremental revenue >=50% of pro-rata target; otherwise pause further spend. - Ongoing KPIs (weekly/monthly): incremental net subscribers, ARPU by cohort, churn by cohort, engagement (hours/viewer), content ROI (cost per incremental sub), CAC payback months, incremental EBITDA, and free cash flow.

**Execution risk controls** - Stage spend: 40/30/20/10% across 4 quarters tied to KPI gates. - Control portfolio: categorize spend by owned IP vs licensed; favor high-ROI owned IP. - Reporting: automated dashboard, weekly exec checks, quarterly board deep-dive.

I can deliver the detailed model (monthly cash flows, full NPV scenarios and tornado charts) and a slide deck for board review.

Financial Modeling Fundamentals and ForecastingHardTechnical

You need to forecast quarterly revenue that is influenced by marketing spend and a macro indicator (consumer confidence). Explain how you would build and validate a SARIMAX model: selecting exogenous regressors, testing stationarity and differencing, identifying AR/MA orders via ACF/PACF, cross-validation/backtesting approach, and how to deploy the model in Python (e.g., statsmodels) while communicating limitations to stakeholders.

Sample Answer

**Approach overview**I would build a quarterly SARIMAX to capture seasonality and the causal effect of marketing spend and consumer confidence (CC). Steps: feature selection, stationarity & differencing, identify AR/MA orders, robust backtesting, deploy in Python, and communicate limitations.

**Select exogenous regressors**- Include marketing spend (lagged: q, q-1) and consumer confidence (contemporaneous and lagged) after testing correlation/Granger causality.- Standardize/scale and create interaction or non-linear transforms if business theory suggests diminishing returns (e.g., log(spend)).

**Stationarity & differencing**- Test target and exog with ADF/KPSS. If quarterly seasonality present, apply seasonal difference (lag=4) and/or first difference.- Example rule: if ADF p>0.05 on level but <0.05 after diff, use d=1; if seasonal unit root, D=1.

**Identify AR/MA orders**- Use ACF/PACF on differenced series: - PACF cut after p lags → AR(p) - ACF cut after q lags → MA(q)- Iterate with information criteria (AIC/BIC).

**Backtesting / validation**- Use rolling-origin (time-series cross-validation): expand or sliding window; for each fold fit model, forecast h quarters, compare RMSE and MAPE. Check residuals for autocorrelation (Ljung-Box) and heteroskedasticity.

**Deploy in Python (statsmodels)**

python

from statsmodels.tsa.statespace.sarimax import SARIMAX
# train: df_train with 'revenue', exog_train (n x k); future_exog for forecast
model = SARIMAX(df_train['revenue'],
                order=(p,d,q),
                seasonal_order=(P,D,Q,4),
                exog=exog_train,
                enforce_stationarity=False,
                enforce_invertibility=False)
res = model.fit(disp=False)
# forecast h steps with future exog
pred = res.get_forecast(steps=h, exog=future_exog)
mean = pred.predicted_mean
conf_int = pred.conf_int()

**Communicate limitations**- Causality vs correlation: marketing may be endogenous; consider instrumenting or distributed lag models.- Forecast uncertainty grows with horizon and exogenous forecast quality—provide scenario-based forecasts (high/medium/low spend & CC).- Model risk: regime shifts, structural breaks—monitor with retraining cadence and alerting.

This approach balances statistical rigor with business interpretability for quarterly revenue forecasting.

Given tables invoices(invoice_id, customer_id, invoice_date, amount, invoice_type ['charge','credit'], recognized_date) and subscriptions(subscription_id, customer_id, start_date, end_date, plan_id), write SQL to compute annual cohort Gross Revenue Retention (GRR) and Net Revenue Retention (NRR) for cohorts defined by subscription start month. Output should include cohort_month, starting_revenue, revenue_end_period, grr, nrr. State assumptions about recognized_date and credits.

Sample Answer

**Approach**- Cohort by subscription start month (date_trunc to month).- Starting revenue = sum of recognized invoice amounts during cohort year (first 12 months from cohort start) for invoices of type 'charge'; treat 'credit' invoices as negative amounts.- revenue_end_period = revenue at end of 12th month (i.e., revenue from cohort customers in month 12).- GRR = (charges retained at month 12 excluding expansion) / starting_revenue. NRR = (charges retained + expansions - churn credits) / starting_revenue.- Assume recognized_date is when revenue is recognized; use that for cohort window. Credits reduce revenue (negative amounts) and invoice_type indicates sign.

SQL (Postgres-style):

sql

WITH cohorts AS (
  SELECT
    s.customer_id,
    date_trunc('month', s.start_date)::date AS cohort_month,
    s.start_date
  FROM subscriptions s
),
rev AS (
  SELECT
    c.cohort_month,
    c.customer_id,
    i.invoice_id,
    i.invoice_type,
    i.amount * CASE WHEN i.invoice_type = 'credit' THEN -1 ELSE 1 END AS amt,
    i.recognized_date
  FROM cohorts c
  JOIN invoices i ON i.customer_id = c.customer_id
  WHERE i.recognized_date >= c.start_date
    AND i.recognized_date < c.start_date + interval '12 months'
),
agg AS (
  SELECT
    cohort_month,
    SUM(CASE WHEN date_trunc('month', recognized_date) = date_trunc('month', start_date) THEN amt ELSE 0 END) AS revenue_month_0,
    SUM(CASE WHEN date_trunc('month', recognized_date) = date_trunc('month', start_date) + interval '11 months' THEN amt ELSE 0 END) AS revenue_month_11,
    SUM(amt) AS revenue_0_to_11
  FROM rev
  GROUP BY cohort_month
)
SELECT
  cohort_month,
  revenue_0_to_11 AS starting_revenue,
  revenue_month_11 AS revenue_end_period,
  CASE WHEN revenue_0_to_11 = 0 THEN NULL ELSE round(revenue_month_11 / revenue_0_to_11::numeric, 4) END AS grr,
  -- For NRR assume credits and upsells reflected in amt already; NRR = revenue_end / starting
  CASE WHEN revenue_0_to_11 = 0 THEN NULL ELSE round(revenue_month_11 / revenue_0_to_11::numeric, 4) END AS nrr
FROM agg
ORDER BY cohort_month;

Assumptions & notes- recognized_date governs attribution. If invoice spans multiple months, require invoices already split by recognized_date.- Credits are negative amounts (invoice_type = 'credit'); expansion invoices are positive charges from same customer.- GRR ideally excludes expansion (upsell) — if expansion invoices are tagged (e.g., plan_change), filter them out when computing GRR. NRR includes expansions. Adjust CASE logic accordingly.

A mid-sized manufacturing company asks you to improve Free Cash Flow by $10 million within 12 months. Propose a prioritized action plan with quantified expected cash impacts, required operational changes, timing, and likely trade-offs or risks for each action (e.g., AR improvements, inventory reduction, vendor renegotiation, capex deferral). Provide assumptions and a short risk mitigation plan.

Sample Answer

**Overview / Goal**I propose a prioritized 12-month action plan to unlock $10M of free cash flow (FCF). Assumptions: revenue $200M, EBITDA margin 8%, working-capital days currently: AR 60, Inventory 70, AP 45. Target: $10M cumulative cash improvement.

**1) AR improvements — target $3.0M (months 1–6)**- Action: tighten DSO from 60→45 days (15-day reduction) via incentives for early pay, stricter credit, automated dunning.- Cash impact calc: (Revenue/365) * DSO reduction ≈ (200M/365)*15 ≈ $8.2M gross; assume 35% collectible timing benefit vs permanent = $2.9M in 12 months.- Operational changes: billing automation, credit policy, sales training.- Trade-offs/risks: possible customer pushback/revenue loss ~0.2–0.5% → mitigate with targeted exceptions and phased rollout.- Mitigation: pilot top 30 customers; offer short-term discounts for accelerated payment.

**2) Inventory reduction — target $3.5M (months 1–9)**- Action: reduce days inventory from 70→50 (20-day cut) via demand planning, SKU rationalization, safety-stock optimization.- Cash impact: (COGS/365)*20; with COGS ~92% of revenue → (184M/365)*20 ≈ $10.1M gross; assume 35% realizable in 12 months = $3.5M.- Ops: S&OP cadence, vendor lead-time reduction, slow-SKU buyback.- Risks: stockouts, service-level decline → mitigate with A/B SKU focus and buffer for critical SKUs.

**3) AP extension / vendor renegotiation — target $1.5M (months 2–8)**- Action: extend payable terms from 45→60 days for non-critical suppliers; negotiate early-pay discounts conversion to longer terms.- Cash impact: (Purchases/365)*15 ≈ (160M/365)*15 ≈ $6.6M gross; assume 25% capture due to supplier limits = $1.65M.- Trade-offs: supplier relations, potential price increases → mitigate via segmentation (apply only to low-risk suppliers), offer consolidated payments.

**4) Capex deferment / prioritization — target $1.5M (months 0–12)**- Action: pause non-critical projects, re-evaluate ROI; defer low-urgency capex.- Cash impact: immediate deferral of $1.5M planned spend.- Trade-offs: potential slower capacity/efficiency gains → document ROI and re-phase high-value projects.

**5) Process & cost efficiency — target $0.5M (months 3–12)**- Action: quick wins in procurement, overtime reduction, utility savings.- Cash impact: $0.5M annualized.- Risks: one-time only; mitigate with continuous improvement KPI.

**Total expected FCF improvement:** ~10.0M

**Key assumptions**- Revenue & COGS estimates as above; realizable percentages reflect timing vs permanent savings; no major market shocks.

**Risk mitigation & governance**- Establish PMO, weekly cash-sprint metrics, 30-day pilots for AR/AP changes, customer/supplier communication plan, service-level KPIs to monitor stockouts and revenue impact.- Escalation thresholds: >0.5% revenue impact or >5% service-level decline triggers pause and review.

Design an A/B experiment to test a new lower-priced mobile-only plan in a specific market. Define treatment and control groups, sample-size and power considerations, primary and secondary metrics (conversion, churn, ARPU, revenue), duration, and potential pitfalls (selection bias, contamination, seasonality).

Sample Answer

**Approach summary** Test whether a lower-priced mobile-only plan in Market X increases net revenue (trading off higher conversion vs. lower ARPU).

**Design: treatment & control** - Control: existing pricing offered to eligible users. - Treatment: the new lower-priced mobile-only plan shown to eligible users. - Randomize at user level within Market X; exclude existing prepaid customers on same promo to avoid crossover.

**Sample size & power (practical)** - For conversion (binary), use standard two-proportion formula:

text

n_per_arm = ( z_{1-α/2} √(2 p̄ (1-p̄)) + z_{power} √(p1(1-p1)+p2(1-p2)) )^2 / (p1-p2)^2

- For ARPU (continuous), use t-test sample-size with baseline σ_arpu and minimum detectable uplift Δ:

text

n_per_arm = 2 ( z_{1-α/2} + z_{power} )^2 σ^2 / Δ^2

- Use α=0.05, power=0.8. As a Financial Analyst, run both calculations and pick the larger n; include inflation (~10–20%) for attrition.

**Primary & secondary metrics** - Primary: incremental weekly revenue per exposed user (net revenue = conversion_rate * ARPU accounting for churn). - Secondary: conversion rate, 30/90-day churn, ARPU, customer LTV projection, margin impact.

**Duration** - Minimum 4–8 weeks to capture acquisition patterns; extend to 90 days for reliable churn/LTV signals or use survival analysis to extrapolate.

**Pitfalls & mitigations** - Selection bias: ensure pure randomization and consistent eligibility rules. - Contamination: block marketing channels that could show both offers; consider user-level assignment. - Seasonality: run concurrently across cohorts or include time-fixed effects in analysis. - Metric leakage: use revenue net of discounts and include cost-to-serve in LTV. - Multiple comparisons: pre-specify primary metric and adjust for secondary tests.

**Finance emphasis** Provide forecasted P&L model with scenarios (best/base/worst), show breakeven acquisition uplift, and recommend go/no-go thresholds based on NPV and payback period.

You're given a monthly revenue CSV exported from two systems ('payments.csv' and 'subscriptions.csv'). The files contain duplicate rows, missing 'amount' entries, inconsistent date formats (e.g., '2021-03-05' and '03/05/2021'), and currency symbols mixed into the 'amount' column. Describe step-by-step how you'd clean, validate, and reconcile these datasets before analysis. Specify checks, deduplication rules, assumptions to document, and how you'd preserve an audit trail for stakeholders.

Sample Answer

**Overview / goals**Clean both CSVs so revenue is accurate, auditable, and ready for analysis: canonical date, numeric amount (USD), no duplicates, and clear provenance.

**Step-by-step plan**1. Ingest- Load with pandas.read_csv(..., dtype=str) to avoid silent coercion.- Keep original raw files unchanged; store copies.

2. Normalize columns- Trim whitespace, lowercase column names.- Standardize amount: remove currency symbols and commas, map empty strings/nulls to NaN, then convert to float.

3. Normalize dates- Parse with pandas.to_datetime(..., infer_datetime_format=True, dayfirst=False) and fallback using multiple formats (e.g., '%Y-%m-%d','%m/%d/%Y').- Flag rows where parsing fails.

4. Validate and impute- Check amount negative/zero outliers; flag refunds vs revenue.- For missing amounts: try join on unique transaction id or match on customer+date; if not resolvable, mark as unresolved and exclude from aggregated revenue but include in audit.

5. Deduplication rules- Define business key: (transaction_id if present) else (customer_id, normalized_date, rounded_amount, source_system).- Keep latest by ingestion timestamp or source priority (payments > subscriptions) and mark duplicates with reason.

6. Reconciliation- Inner-join on transaction_id where available; otherwise fuzzy-match on customer+date+amount using tolerance (e.g., $0.50) and document matches.- Produce summary: totals by system, matched, unmatched, and net difference.

**Checks and QA**- Row counts before/after, sum(amount) before/after, sample-based verification (10 random transactions against source).- Distribution checks by date and customer to spot spikes.

**Assumptions to document**- Currency (assume USD unless metadata says otherwise)- Tolerance for fuzzy matches- Priority when duplicates exist- Treatment of missing amounts (excluded from totals)

**Audit trail**- Keep raw files immutable.- Save cleaned intermediate datasets with timestamps and transformation logs (CSV + a human-readable changelog).- Add columns: source_file, ingestion_ts, cleaned_by_script_version, dedup_action, match_confidence.- Export reconciliation report (CSV+PDF) and store in shared location with checksums.

This approach ensures reproducible, verifiable revenue figures and clear documentation for stakeholders.

Explain how you would forecast operating working capital by modeling DSO (Days Sales Outstanding), DPO (Days Payable Outstanding) and DIO (Days Inventory Outstanding). Provide formulas to convert days into balance sheet levels and demonstrate how an increase in DSO affects cash flow and free cash flow.

Sample Answer

**Approach (brief)** As a financial analyst I forecast operating working capital by projecting DSO, DPO and DIO drivers, converting those days into balance-sheet balances, and then linking changes to cash flow and free cash flow. I use revenue, COGS and supplier spend drivers rather than absolute historical balances to keep the model scalable.

**Key formulas (convert days → balance-sheet)**

text

Accounts Receivable (AR)  = Revenue  / 365  *  DSO
Inventory (INV)          = COGS     / 365  *  DIO
Accounts Payable (AP)    = COGS     / 365  *  DPO

Plain-English: multiply daily run-rate (Revenue/365 or COGS/365) by forecasted days.

**How DSO increase affects cash flow & FCF** - If DSO rises, AR increases → cash tied up in receivables increases → operating cash flow decreases by the AR change. - Example: Revenue = $365m (daily = $1m). DSO increases 30 → 40 days: ΔAR = $1m * (40-30) = $10m. Operating cash flow falls by $10m that period (all else equal). - Free cash flow (FCF) impact:

text

FCF = EBIT*(1 - tax) + Depreciation - CapEx - ΔNWC
ΔNWC ≈ ΔAR + ΔINV - ΔAP

So ΔDSO↑ → ΔAR↑ → ΔNWC↑ → FCF↓ by same cash amount (assuming no offsetting changes).

**Modeling notes & best practices**- Project days from drivers (customer mix, contract terms, seasonality) not just trend-fit. - Sensitivity table for ± days to show cash / FCF impact. - Consider timing (phased collection) and bad-debt assumptions; link working-capital to cash conversion cycle for holistic analysis.
