Summary

Google PM interview with a single strategy question about whether to expand GCP infrastructure into Portugal. Not a lot of context to go off, but it's the kind of question that sounds deceptively simple until you realize how many angles there are.

I'd probably start by fumbling around market sizing before realizing the real crux is strategic fit, not just demand.

Suggested Approach

Start by clarifying the strategic objective behind building a new GCP region—whether it's market expansion, latency reduction, data sovereignty, or competitive pressure. Then evaluate the decision through a structured framework that weighs demand signals, economic viability, technical feasibility, and strategic alignment, while acknowledging trade-offs and risks. Conclude with a clear recommendation and the key metrics or milestones you'd use to validate it.

Pro tip: Show that you understand Google's cloud business model by framing the decision in terms of unit economics (e.g., cost per region, utilization thresholds) and competitive dynamics (e.g., AWS and Azure presence in Iberia), rather than just technical or geographic factors.

1. Clarify the strategic goal

Ask what problem the new region solves: Is it to capture untapped demand, improve latency for existing users, meet data residency requirements, or counter competitor moves? Align the decision with Google Cloud's overall strategy.

2. Assess demand and market potential

Analyze current and projected demand from Portuguese and nearby customers, including latency-sensitive workloads, regulated industries, and local enterprises. Consider existing regions (e.g., Madrid, London) and whether they already serve the market adequately.

3. Evaluate economic viability

Estimate costs (infrastructure, operations, staffing) and revenue potential. Calculate break-even utilization and ROI. Compare against alternative investments (e.g., expanding existing regions, edge locations).

4. Consider technical and operational feasibility

Evaluate site selection factors: power, connectivity, talent, regulatory environment, and latency to major population centers. Assess impact on network architecture and ability to offer all GCP services.

5. Make a recommendation and define success metrics

Synthesize findings into a go/no-go recommendation with conditions. Define KPIs (e.g., adoption rate, latency improvement, revenue targets) and a phased rollout plan to mitigate risk.

Key Points to Mention

Total cost of ownership and unit economics of a new region, including break-even analysis
Competitive landscape: AWS and Azure presence in Iberia and potential first-mover advantage
Latency and data sovereignty requirements for Portuguese and EU customers
Synergies with existing Google investments in Portugal (e.g., data centers, offices, submarine cables)
Opportunity cost: comparing against other regions or edge deployments
Regulatory and compliance factors (GDPR, EU data localization trends)
