Engineering Systems interview prep.

Systems + integration + functional safety + V&V engineers at vehicle OEMs (legacy and EV / new entrants).

What interviewers look for

  • Can the candidate apply SE V-model to a vehicle / ECU - requirements + decomposition + ICDs + V&V?
  • Do they understand ISO 26262 functional safety - ASIL hazard analysis, safety goals, safety case?
  • Are they fluent in ASPICE software process + IATF 16949 quality requirements?
  • Can they think volume + cost + manufacturability - BOM cost, PPAP, Cpk?
  • Do they understand ADAS / AD / SAE J3016 + emerging regulatory landscape?
  • Are they cost-aware - automotive cost-of-goods discipline distinct from aero / med-device?
  • Long-game fit - tech lead / chief engineer / vehicle integration leader trajectory?

Behavioural questions to expect

  1. Walk me through your engineering background + automotive experience.

    What it tests: Story arc - engineering training, vehicle / ECU exposure, safety + cost awareness.

  2. Tell me about a vehicle programme or ECU you've worked on.

    What it tests: Programme thinking - SE + integration + V&V + cost + manufacturing.

  3. Why automotive vs aerospace / consumer / other engineering paths?

    What it tests: Authentic alignment - mass-scale impact, cost discipline, electrification transformation, multi-decade fleet thinking.

  4. Why this segment - ICE / hybrid / BEV / ADAS / commercial?

    What it tests: Specificity. Generic answers fail.

  5. Why this firm?

    What it tests: Real homework - product, recent moves, engineering culture - not name-drop.

  6. What's your read on our product portfolio + recent launches?

    What it tests: Industry literacy - segment position, product mix, competitive picture.

  7. Tell me what you understand about our engineering culture + SE practice.

    What it tests: Engineering org maturity - SE function authority, ISO 26262 / ASPICE / IATF maturity, launch cadence.

  8. Walk me through a vehicle / ECU requirements + integration case.

    What it tests: Auto SE fluency - vehicle-level + ECU partition + ICDs + integration test.

Technical concepts to master

Vehicle SE + ECU / E/E architecture

Vehicle-level + ECU requirements
Vehicle features (e.g. lane keeping) decomposed into ECU functions + interfaces.
E/E architecture evolution
Domain controllers + zonal architectures replacing 70-100 individual ECUs - simplifies wiring + enables SDV.
In-vehicle networks
CAN / CAN-FD / FlexRay / LIN / MOST / Automotive Ethernet - bus technologies connecting ECUs.
AUTOSAR
AUTomotive Open System ARchitecture - standardised software architecture (Classic + Adaptive).

ISO 26262 functional safety

Item definition + HARA
Item = system being analysed. HARA = Hazard Analysis + Risk Assessment to derive safety goals + ASIL.
Safety goals + FSR / TSR
Safety goals -> Functional Safety Requirements -> Technical Safety Requirements.
Architecture + diagnostic coverage
Safety architecture (e.g. monitor-checker, dual MCU, lockstep) + diagnostic coverage of hardware faults.
Safety case
Structured argument that the item is safe - body of evidence + reasoning per ISO 26262.

ADAS + AD + SAE J3016 levels

SAE J3016 levels (0-5)
L0 = no automation; L2 = partial automation (driver monitors); L3 = conditional (driver intervenes on request); L4 = high (within ODD); L5 = full automation.
ODD (Operational Design Domain)
Specific operational conditions under which an automated system is designed to function safely.
Sensor suite + sensor fusion
Camera + radar + lidar + ultrasonic + V2X combined for redundant perception.
ML / AI + automotive safety
ML perception + behaviour models in safety-critical context - SOTIF + emerging ML safety standards.

IATF 16949 + APQP + PPAP

IATF 16949
Quality management standard for automotive production + service parts - mandatory for automotive supply chain.
APQP (Advanced Product Quality Planning)
AIAG standard 5-phase planning method for new product development through launch.
PPAP (Production Part Approval Process)
Standardised submission package demonstrating supplier readiness for production - 18 elements at most stringent level.
DFMEA + PFMEA + Cpk
Design + Process FMEA = systematic failure mode analysis. Cpk = process capability index (1.33+ typical target).

Practical drills

  • You're SE lead for a new domain controller. Walk through your requirements + ECU partition + V&V approach.
  • Your team is designing a new propulsion control function. Walk through ISO 26262 - HARA + ASIL + safety architecture.
  • A Tier 1 has reported a recurring field failure traced to a tier 2 component. PPAP was approved 18 months ago. Walk through your engineering + quality response.

Smart-question anchors

  • Product portfolio + powertrain mix - ICE / hybrid / BEV / FCEV; launch cadence
  • Engineering org + SE authority - platform / vehicle line structure
  • Functional safety + cybersecurity posture - ISO 26262 + ISO 21434 maturity
  • Software + OTA + SDV strategy - architectural transition pace
  • Supply chain + manufacturing - Tier 1 relationships, IATF 16949, vertical integration
