Engineering Systems interview prep.

Behavioural questions to expect

1. Walk me through your CV.
2. Tell me about your most impactful SoC or system project.
3. Tell me about a weakness, a failure, or feedback you've received and worked on.
4. Why SoC systems engineering - and why this firm vs other chip companies or software?
5. Which systems sub-specialty would you focus on - SoC architecture / IP integration / system validation / post-silicon?
6. Why the firm?
7. How would you describe the firm's SoCs + system approach in your own words?
8. How does SoC systems engineering actually drive value for a hardware company?

Technical concepts to master

• SoC architecture + IP integration

  Block partitioning · Interconnect choice (AXI / CHI / NoC) · Memory subsystem design · Power + clock + reset architecture

• System PPA + use-case modeling

  Workload + use-case modeling · Thermal + power envelope · Perf-per-watt + perf-per-mm2 · Bandwidth + latency budget

• HW/SW co-validation + bring-up

  Emulation (Palladium / ZeBu) · FPGA prototype · Portable Stimulus (PSS) · Post-silicon bring-up

• Chip-to-product flow + tapeout discipline

  Architecture → RTL → physical → SW · Tapeout milestone · Bring-up + customer enablement · First Customer Ship (FCS) + steppings

Practical drills

• Architect an SoC for an edge-AI inference use case at the firm - 10W TDP, 30 FPS object detection at HD, $20 BOM target. Walk me through.
• Your SoC is 20% short on perf-per-watt for a customer's AI workload. Walk me through analysis + fix options.
• Plan the validation + bring-up for the edge-AI SoC from drill 1 - pre-silicon through customer first boot.

Smart-question anchors

• Team + scope - team shape, what the role would own in 6-12 months
• SoC + product roadmap - current + next SoC, process node, customer + use case
• Architecture + system culture - in-house vs licensed IP, interconnect + memory approach
• Validation + tool stack - emulation hours, FPGA platforms, PSS adoption, bring-up culture
• Tapeout + bring-up + customer ship - cadence, recent post-silicon experiences, customer enablement
