How to use this page
Don't memorise answers. For each question, read what the interviewer is looking for, then practise answering out loud in your own words with a real example. The notes describe strong answers and common red flags — they are for your prep, not a script.
Demand Forecasting
2 questionsHow do you approach forecasting demand for a product with variable sales?
AdvancedWhat the interviewer is looking for: Strong answers use historical data, seasonality, and business input, quantify error, and adjust methods to the pattern. A single naive average with no error tracking is a red flag.
A forecast was badly wrong and caused a stockout. How do you handle it?
IntermediateWhat the interviewer is looking for: Look for analysing why, improving the model, and communicating transparently rather than blaming. Ignoring forecast error is a red flag.
Inventory Management
1 questionHow do you balance inventory to avoid both stockouts and excess?
IntermediateWhat the interviewer is looking for: Look for safety stock, reorder points, service-level targets, and carrying-cost trade-offs. Overstocking capital or frequent stockouts are red flags.
Logistics
1 questionHow do you analyse and optimise logistics costs?
IntermediateWhat the interviewer is looking for: Strong candidates analyse routes, modes, and lead times, trading cost against service. Cutting logistics cost while ignoring service impact is a red flag.
Data Analysis
2 questionsHow do you use Excel and SQL to turn supply chain data into decisions?
IntermediateWhat the interviewer is looking for: Look for pulling and modelling data reliably, validating it, and drawing actionable conclusions. Producing numbers with no recommendation is a red flag.
How do you build a supply chain dashboard people actually use?
IntermediateWhat the interviewer is looking for: Look for focusing on the KPIs that drive decisions and keeping it clear. A cluttered dashboard with every metric is a red flag.
SQL
1 questionWalk me through a query you'd write to analyse supplier performance.
IntermediateWhat the interviewer is looking for: Strong candidates aggregate on-time delivery, defect rates, and cost by supplier and validate results. Not being able to write basic aggregation is a limitation.
Risk Management
1 questionA key supplier's lead times become unreliable. How do you respond?
AdvancedWhat the interviewer is looking for: Look for quantifying the impact, adjusting safety stock, and developing alternate sources. Ignoring the risk until a stockout is a red flag.
ERP Systems
1 questionHow do you use an ERP system to keep supply chain data accurate?
BasicWhat the interviewer is looking for: Strong answers rely on the ERP as the source of truth, keep master data clean, and reconcile. Working off disconnected spreadsheets is a red flag.
Process Improvement
1 questionHow do you identify and drive a process improvement in the supply chain?
IntermediateWhat the interviewer is looking for: Look for finding the bottleneck with data, testing a change, and measuring the result. Changing processes on gut feel is a red flag.
Vendor Management
1 questionHow do you evaluate and manage vendor performance?
IntermediateWhat the interviewer is looking for: Strong candidates use scorecards on cost, quality, and delivery and hold constructive reviews. Judging vendors purely on price is a red flag.
Supply Chain Management
1 questionHow do you analyse cost across the supply chain to find savings?
AdvancedWhat the interviewer is looking for: Strong answers look end-to-end — sourcing, inventory, logistics — and quantify trade-offs, not just squeeze one lever. Local cost cuts that raise total cost are a red flag.
Power BI
1 questionHow do you visualise supply chain trends in Power BI for stakeholders?
BasicWhat the interviewer is looking for: Look for dashboards focused on decision-relevant KPIs, kept clean and current. Cluttered dashboards with every metric and no insight are a red flag.
Behavioural & role-general
2 questionsTell me about an analysis that improved a supply chain outcome.
BasicWhat the interviewer is looking for: Strong answers give a concrete change and measurable impact — cost, service, or inventory — with ownership. Vague claims with no numbers are a red flag.
How do you balance cost, service level, and risk in supply chain decisions?
IntermediateWhat the interviewer is looking for: Look for treating it as a trade-off tied to business priorities, not optimising one dimension blindly. Ignoring resilience for pure cost is a red flag.
