← Google Cloud (GCP) Interview Insights
This one tripped me up a bit because airports feel niche but actually have a ton of edge cases.
Start by clarifying the goal and constraints with the CEO, then segment airport travelers to identify key pain points. Propose a cloud-native ATM solution that leverages GCP services for scalability, real-time data, and personalization, and outline a phased rollout plan with success metrics.
Pro tip: Emphasize how GCP's global infrastructure and data analytics can enable features like multi-currency support and personalized offers, turning the ATM into a revenue-generating channel. Also, show adaptability by acknowledging potential regulatory and security challenges and how you'd address them.
Ask the CEO about the primary goal (e.g., revenue, customer experience, data collection) and any constraints (budget, timeline, regulatory). This ensures alignment and focuses your solution.
Identify key user segments (e.g., business travelers, tourists, crew) and their needs: quick cash, multi-currency, language support, etc. Use this to prioritize features.
Brainstorm features that leverage GCP: real-time currency conversion, personalized offers via BigQuery/ML, remote monitoring with IoT Core, and contactless transactions. Focus on differentiators.
Propose metrics like transaction volume, user satisfaction, and revenue per ATM. Outline an MVP with core features and a roadmap for iterative improvements.
Discuss security, compliance (e.g., PCI DSS), and operational challenges. Suggest a pilot at a few airports, then scale based on learnings.
