If our demand is highly volatile and we have only three months of sales history, how would you build an initial demand forecast and update it over time?
Employers ask this question to see how you handle ambiguity and build practical forecasting in a startup. In your answer, show you can start simple, combine quantitative and qualitative inputs, and iterate frequently. Mention methods, leading indicators, and a review cadence with bias tracking.
Answer Example: "I’d start with a simple exponential smoothing baseline and overlay qualitative inputs from sales pipeline, promo calendars, and web traffic. I’d create best/base/worst cases with confidence intervals, then review weekly as we learn, tracking forecast bias and MAPE. As signals strengthen, I’d layer in causal variables and shorten/lengthen the time horizon by SKU class. I’d document assumptions so we can quickly pivot without losing context."

Walk me through your process for setting safety stock and reorder points to balance service levels with cash constraints.
Employers ask this question to assess your grasp of inventory control and financial trade-offs. In your answer, explain how you translate service targets into math while respecting cash and MOQ realities. Show you can segment SKUs and incorporate lead time variability.
Answer Example: "I segment SKUs by ABC/criticality and set service targets accordingly, then calculate safety stock using demand and lead-time variability (Z*σLT). Reorder points are safety stock plus demand during lead time, adjusted for supplier MOQs and batch sizes. I watch cash-to-cash and inventory turns, and I run sensitivity analyses to show the cost of higher service. I pilot changes on a subset before scaling."

Tell me about a time you sourced a new supplier under tight timelines. How did you vet them and negotiate terms?
Employers ask this question to evaluate your speed, diligence, and negotiation under pressure. In your answer, outline a structured but fast sourcing process with risk mitigation. Include qualification steps, trial runs, and key terms you negotiated.
Answer Example: "Facing a six-week timeline, I issued a rapid RFQ to five pre-qualified vendors, scored them on price, lead time, quality certifications, and capacity, and ran a small pilot order. I negotiated FOB terms, price breaks tied to volume, and a flexibility clause for expedited lots. We included quality hold points and a 90-day review to adjust MOQs. The supplier delivered on time, and we saved 12% versus the incumbent."

What is your approach to choosing shipping modes and Incoterms for international shipments?
Employers ask this question to gauge your logistics knowledge and risk management. In your answer, discuss cost, lead time, risk, and ownership trade-offs. Reference commonly used Incoterms and how you collaborate with freight forwarders and suppliers.
Answer Example: "I balance value density and urgency to choose air vs. ocean, and I model landed cost and lead-time risk. For Incoterms, I often prefer FOB for control of freight and transparency, but will use DDP for customer simplicity if we have broker support. I work with forwarders to plan consolidations and buffer for port congestion. I document responsibilities, insurance, and customs instructions up front."
