Walk me through your background + path into automotive supply chain.

What it tests: Story arc - quantitative / engineering / commercial training + auto or adjacent supplier exposure + concrete APQP / PPAP / commodity / launch work. Interviewers screen for candidates whose path lands on auto supply chain deliberately, not as default.

Tell me about a supply chain project you've owned end-to-end.

What it tests: Planning + supplier + plant rigor under auto cadence. Can the candidate walk problem framing -> data -> action -> sustained outcome across APQP gates, supplier interface, and plant launch / run-rate reality.

Why automotive supply chain vs general industrial / consumer / aerospace?

What it tests: Authentic alignment - JIT / JIS line cadence, multi-tier complexity, EV transition stakes, high-volume cost discipline, supplier-development culture.

Why supply chain specifically vs engineering, manufacturing, finance, or commercial roles?

What it tests: Specificity. Generic 'I like supplier relationships' or 'I like analytics' fails.

What it tests: Real homework - powertrain + plant footprint + recent supply moves + supplier culture - not 'great brand' or 'iconic name'.

What's your read on our vehicle portfolio + plant footprint?

What it tests: Industry literacy - powertrain mix, plant geography, launch cadence, where the supply chain team likely focuses (legacy ICE run-rate vs EV ramp vs commercial).

Tell me what you understand about our supply chain organization and recent strategic moves.

What it tests: Engineering + maturity awareness - APQP / PPAP cadence, JIT / JIS maturity, supplier strategy, battery / semi / nearshoring moves.

Walk me through how you'd handle a line-down event - supplier shortage, quality reject, or logistics failure.

What it tests: Line-down playbook fluency - hour-by-hour response, allocation discipline, expedite vs alternative-source decision, structural follow-up. Most-common opening question for auto buyer / supplier quality / plant logistics roles.

Supply Chain interview prep.

Trained on planner / buyer / commodity buyer / category sourcing / supplier quality / S&OP lead / materials manager / plant logistics / supply chain manager / director interviews across legacy OEMs + EV / new entrants.

What interviewers look for

Can the candidate run APQP + PPAP discipline cold - 5 phases, 18 elements, PSW sign-off, gates?
Do they understand JIT / JIS line sequencing - sequenced delivery, in-line sequencing, broadcast windows?
Are they fluent in multi-tier supply continuity - Tier-2 / Tier-3 visibility, semi shortage playbook, line-down response?
Can they speak automotive commodity strategy - semis, wire harness, castings, stampings, motors, batteries, rare earths?
Do they understand launch ramp + SOP economics - PPAP timing, capacity ramp, supplier readiness?
Can they speak EV / battery supply - cells, cathode minerals (Li / Ni / Co), IRA + CSDDD compliance?
Are they grounded in cost-down + productivity - annual 3-5% target, VAVE, should-cost, supplier development?
Long-game fit - buyer / senior / commodity manager / director / VP / CPO trajectory?

Technical concepts to master

APQP + PPAP supplier qualification

APQP (Advanced Product Quality Planning): AIAG-defined 5-phase quality planning method for automotive product + process development from sourcing through SOP and run-rate.
PPAP (Production Part Approval Process): AIAG-defined 18-element supplier submission package demonstrating production readiness; gated by PSW (Part Submission Warrant).
DFMEA + PFMEA + control plan: DFMEA = Design Failure Mode + Effects Analysis (engineering-led); PFMEA = Process FMEA (manufacturing-led); Control Plan = the resulting in-process controls.
Cpk + MSA: Cpk = process capability index measuring how centered + consistent a process is vs spec (target 1.33+; 1.67+ for safety-critical). MSA = Measurement System Analysis to qualify gauge / instrument before production.

Automotive commodity strategy + supplier development

Should-cost + clean-sheet costing: Build-up of part cost = material + labor + overhead + SG&A + margin, benchmarked vs current quote to expose negotiation lever. Clean-sheet = should-cost from first principles.
Dual-source vs single-source vs sole-source: Dual-source = two qualified suppliers per part (resilience + leverage); single-source = chose one of multiple available; sole-source = only one supplier exists (rare-earth, specialty alloy, specific semi).
LTA + indexed material pass-through: Long-Term Agreement (typically 3-5 years) with volume commitment, productivity glide-path (2-5% annual), and indexed material clause (steel / aluminum / copper / resin pegged to public index).
Supplier development + supplier quality engineering: On-site engineering + lean help to improve supplier cost, quality (PPM), capacity, or capability. Distinct from arms-length buying.

JIT / JIS line execution + materials flow

Broadcast window + sequenced delivery: Broadcast = vehicle build sequence signal sent to JIS supplier (typically 2-8 hours ahead of body-in-white through paint into general assembly); supplier sequences parts matching VINs and delivers to line.
Kanban + pull replenishment: Kanban = visual signal-based replenishment (two-bin, electronic e-kanban, RFID); pull = downstream demand triggers upstream replenishment. Foundation of TPS / lean production.
Build-to-schedule + build-to-broadcast: Build-to-schedule = supplier builds to weekly / daily schedule + ships in bulk; build-to-broadcast = supplier builds in real-time matching VIN sequence.
Line-down cost economics: Per-hour cost of stopped assembly line - direct labor idle, depreciation, opportunity cost, downstream catchup; typically $10K-$100K+ per hour depending on plant + segment.

EV / battery supply + IRA / CSDDD + trade

Battery cell sourcing - JV / off-take / vertical integration: OEM cell supply via Tier-1 partnership with major Korean / Japanese / Chinese cell makers, JV with cell maker, off-take agreement, or vertical integration (in-house cell production).
Cathode + critical minerals - Li / Ni / Co / graphite / rare earth: Battery cathode mineral supply concentrated geographically - Li (Australia + Chile + China processing), Ni (Indonesia + Russia + Canada), Co (DR Congo dominant), graphite (China processing), rare earths (China dominant in NdFeB magnets).
IRA Section 30D + FEOC + battery sourcing requirements: US Inflation Reduction Act Section 30D EV tax credit ($7,500) conditional on - critical mineral % from US / FTA partner (40% in 2024 -> 80% by 2027) + battery component % from North America (50% in 2024 -> 100% by 2029) + no FEOC (Foreign Entity of Concern) content.
EU CSDDD + battery passport + scope-3: EU Corporate Sustainability Due Diligence Directive (CSDDD, 2024) + EU Battery Regulation (battery passport, carbon footprint, recycled content, due-diligence) impose supply chain disclosure + due-diligence at supplier level.

Practical drills

You manage a $40M annual spend commodity (machined castings) with current supplier on a 3-year LTA. Annual productivity commitment is 3%; steel index pass-through is in place; current PPV running -1.5% YTD (unfavorable). Engineering proposes a VAVE redesign (wall-thickness reduction) that should yield $1.8M savings + 4-month implementation. Should-cost on a competing dual-source quote shows $0.9M opportunity but requires 12-month PPAP + $400K tooling. Walk through the economics + recommendation.
It's 6am Monday. The plant manager calls - the body-in-white line is going down in 4 hours because a Tier-1 wire harness supplier in Mexico had a fire over the weekend. Inventory at the plant covers 18 hours; sister-plant has 3 days. The harness is a JIS-sequenced part with 47 trim-level variants. Walk me through your first 24 hours and the structural follow-up.
Your OEM is launching a new BEV crossover in 30 months. Battery cell options are - (a) existing JV partner with a US plant (NCM cathode, fully IRA-compliant, $130/kWh contracted, 18-month capacity ramp); (b) Chinese cell maker with superior LFP cost ($95/kWh) but FEOC-restricted under IRA (loses $7,500 tax credit, would need to be sold without credit or relocated); (c) Korean supplier with US plant under construction (LFP, $110/kWh, but plant not ready until SOP+12 months, requiring bridge supply). Cathode minerals also need IRA + CSDDD compliance check. Walk me through how you'd structure the decision and what additional data you'd need.
