Warehouse Operations interview prep.
Trained on DC manager / fulfillment ops manager / shift supervisor / general-manager-of-DC / area manager interviews across retail DCs, e-commerce fulfillment centers, contract logistics sites, parcel hubs, cold-storage, and industrial / B2B distribution.
What interviewers look for
- Can the candidate run a shift safely - OSHA discipline, MHE risk, near-miss program, daily safety conversation?
- Do they own labor + productivity - UPH, lines / hour, attrition, overtime, span of control - as daily numbers?
- Are they fluent in inbound + outbound flow mechanics - receiving, putaway, slotting, picking, packing, shipping, returns?
- Can they read + drive WMS configuration - wave strategy, task interleaving, slotting, cycle count?
- Do they handle people leadership - 1:1s, performance management, retention, peak hiring + onboarding?
- Are they grounded in MHE + automation reality - forklifts, conveyors, AS/RS, AMRs, GTP - and the safety + reliability that wraps them?
- Can they navigate peak season - capacity ramp, flex labor, dock + door utilization, contingency?
- Long-game fit - shift supervisor / ops manager / senior ops / general-manager-of-DC / regional director trajectory?
Behavioural questions to expect
Walk me through your background + your path into warehouse / fulfillment operations.
What it tests: Story arc - operational training + floor exposure + labor-leadership work + KPI discipline. Interviewers screen for candidates whose path lands on warehouse ops as deliberate, not a fallback.
Tell me about a shift, area, or site you've owned end-to-end on the floor.
What it tests: Floor-leadership rigor + safety + labor + KPI lens. Can the candidate walk a normal shift from start-up huddle to end-of-shift handover cleanly.
Why warehouse operations vs transportation, planning, or commercial roles?
What it tests: Authentic alignment - floor pace, labor-leadership stakes, daily KPI ownership, tangible flow of goods vs pure analysis.
Why fulfillment / DC ops specifically vs transportation ops or network planning?
What it tests: Specificity. Generic 'I like operations' fails.
Why this firm?
What it tests: Real homework - site profile + customers + automation + recent moves - not 'great brand'.
What's your read on our site network + customer footprint?
What it tests: Industry literacy - site type, customer concentration, recent moves, where the ops team likely focuses.
Tell me what you understand about our automation + safety posture.
What it tests: Engineering + safety maturity awareness - automation footprint, WMS platform, OSHA record, named safety programs.
Walk me through a time you lifted productivity - UPH, lines / hour, or dock-to-stock - on a site or area.
What it tests: Operational rigor + KPI fluency - can the candidate baseline, diagnose, intervene, and sustain on a productivity metric.
Technical concepts to master
WMS, slotting + wave strategy
- WMS (Warehouse Management System)
- Software directing receiving, putaway, slotting, picking, packing, shipping, cycle count - core system of record for the four-wall operation. Major platforms: Manhattan Active WM, Korber (HighJump), Blue Yonder, and the major enterprise-ERP-bundled WMS modules.
- Slotting
- Assigning SKUs to pick locations to minimise travel + congestion - velocity-based (A-B-C) + cube-based + family-grouped.
- Wave + batch + cluster picking
- Wave = group of orders released together for picking; batch = picker picks multiple orders in one pass; cluster = picker carries multiple containers and picks to each.
- Task interleaving
- WMS directs MHE operators to combine putaway + replenishment + picking + cycle count in one trip rather than separate dedicated trips.
Labor planning + productivity
- Labor management system (LMS)
- Engineered standards + time-study-based productivity tracking by task + associate (Manhattan LMS, Korber LMS, Easy Metrics, ProTrack).
- Span of control + supervisor ratio
- Front-line supervisor span - typical 15-25 associates per supervisor; area / ops manager 3-5 supervisors per direct report.
- Flex labor + agency strategy
- Mix of permanent + agency + seasonal labor - typical permanent 60-80%, flex 20-40% sized to peak ratio.
- Attrition + retention
- DC industry attrition is structurally high (35-100%+ annualised) - drivers: wage, supervisor quality, onboarding, schedule, safety, culture.
Safety + OSHA fundamentals
- OSHA TRIR + DART
- Total Recordable Incident Rate + Days Away / Restricted / Transferred rate - calculated as incidents x 200,000 / labor hours worked.
- Hierarchy of controls
- Elimination > substitution > engineering controls > administrative controls > PPE - the canonical ranking for hazard mitigation.
- PIT (Powered Industrial Truck) program
- OSHA 1910.178 - certification, daily inspection, traffic + pedestrian separation rules for forklifts + reach trucks + pickers.
- Behaviour-based safety + near-miss reporting
- Programs that engage associates in observing + reporting unsafe behaviours + conditions - shifts from lagging to leading indicators.
Inbound + outbound flow fundamentals
- Receiving + ASN
- Trailer arrival, dock scheduling, unload, ASN (Advance Ship Notice) match, exception handling.
- Putaway + replenishment
- Move from receiving dock to storage location (putaway) + replenish pick faces from reserve (replenishment).
- Picking
- Discrete (one order at a time), batch (multi-order single pass), cluster (multi-tote single pass), zone (multi-zone consolidation) - choice driven by order profile + cube + velocity.
- Packing + value-add
- Order consolidation, packing, labeling, customization (gift wrap, kitting, light assembly, returns refurb).
Practical drills
- Your e-com FC needs to ship 30,000 units / day at peak vs 12,000 / day at baseline. Average picker UPH is 90, packer UPH is 60. Shifts are 8 hours productive. Walk me through your labor build, identify the bottleneck, and tell me how many flex labor heads to add. Show your numbers.
- A 400-associate e-com FC has seen picker UPH drop from 110 to 85 over 6 weeks. OTIF is slipping, overtime is up 30%. The site general manager has asked you to diagnose + fix in 4 weeks. Walk me through your approach.
- You're the site general manager of a 1M sq ft e-com FC handling 80,000 units / day baseline, peaking to 250,000 / day in November + December. You have 6 weeks to plan. Walk me through your peak planning playbook.
Smart-question anchors
- Site network + customer mix - where the ops team's focus areas + growth are likely
- Automation + WMS maturity - AS/RS, AMRs, GTP, conveyor + sortation, WMS standard + recent investments
- Safety posture + culture - TRIR / DART trend, named programs, OSHA history, leading-indicator focus
- Labor model - union vs non-union, wage band, attrition reality, peak hiring playbook, retention programs
- KPI scorecard + cadence - daily / weekly / monthly KPIs the operating leader is accountable for
