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.
Interview loop matrix
| Stage | What they probe | Format | Pass signal |
|---|---|---|---|
| Recruiter screen | Partner vs direct mix, coding bar, travel, clearance if any | 30–45 min call | You clarify delivery ownership vs pure advisory SA work |
| Technical screen | GCP fundamentals, APIs, debugging, possibly coding | Exercise or discussion | Practical systems reasoning under enterprise constraints |
| Estate / landing-zone deep dive | IAM, VPC, private endpoints, org policy, perimeter | Architecture talk | Least privilege and network boundaries by default |
| Vertex / GenAI delivery | RAG, agents, evals, model routing, grounding | Design + critique | Permissions-first retrieval; rollout gates |
| Customer / partner case | Scoping, thin slice, stakeholders, reusable patterns | Ambiguous scenario | Measurable MVP that survives security review |
| Behavioral / HM | Ambiguity, executive updates, multi-account enablement | Story-driven | Outcome language without blaming the customer |
Grading rubric
| Dimension | Strong | Weak |
|---|---|---|
| Identity & perimeter | Designs IAM, least privilege, and data boundaries early | Adds auth and egress controls as an afterthought |
| Platform realism | Private networking, org policy, and cost as design inputs | Assumes public demos equal production |
| GenAI production sense | Retrieval vs generation diagnosis; eval + spend ceilings | Demo wow without rollout gates |
| Scope control | One workflow / one persona / one measurable KPI | Boil-the-ocean landing-zone rebuild in phase one |
| Partner / reuse judgment | Patterns that transfer across accounts without fragile forks | Every customer gets a one-off snowflake forever |
| Day-2 ownership | Monitoring, rollback, and handoff owners named | Stops at “we enable Vertex” |
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
- Customer wants grounded chat over Drive + BigQuery with no public egress — what ships in 30 days?
- A Vertex RAG demo leaks cross-team documents — how do you diagnose and gate rollout?
- 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
- Day 1–2 — GCP IAM / networking / perimeter constraint refresh
- Day 3 — Vertex RAG diagnosis + eval gates
- Day 4 — Full customer case with thin slice
- Day 5 — Cost / latency budgeting drill
- Day 6 — Behavioral: partner enablement vs owned delivery
- Day 7 — Mock loop; score on the rubric
