Interview

Google Cloud GenAI FDE interview guide

Google Cloud GenAI Partner / FDE-shaped loops test whether you can land Vertex AI inside real customer (or partner-multiplied) estates — identity, networking, evals, and adoption — not reference-architecture theater alone.

Hyperscaler titles blur across Partner Engineer, Specialist SA, and Forward Deployed GenAI. Lock coding bar, travel, and whether KPIs are ARR assist or in-account outcomes before you over-prepare the wrong loop.

Red flags

  • Ignoring IAM / VPC / perimeter constraints in a Vertex design
  • No cost or latency budget for model calls
  • Confusing SA reference architecture with FDE delivery ownership
  • Cannot define a thin vertical slice inside an existing GCP estate
  • Partner motion with no reusable pattern — only per-account heroics

Practice scenarios

  1. Customer wants grounded chat over Drive + BigQuery with no public egress — what ships in 30 days?
  2. A Vertex RAG demo leaks cross-team documents — how do you diagnose and gate rollout?
  3. Partner SI needs a repeatable pattern across three accounts — what do you productize vs leave custom?

Pair with Enterprise RAG, AWS FDE guide, Microsoft FDE guide, and the stack alignment checker.

7-day prep plan

  1. Day 1–2 — GCP IAM / networking / perimeter constraint refresh
  2. Day 3 — Vertex RAG diagnosis + eval gates
  3. Day 4 — Full customer case with thin slice
  4. Day 5 — Cost / latency budgeting drill
  5. Day 6 — Behavioral: partner enablement vs owned delivery
  6. Day 7 — Mock loop; score on the rubric
