AI Coach Tip: In e-commerce platform architect interviews, demonstrate both technical depth and business understanding. When discussing system designs, follow a structured approach: clarify requirements, identify key components, explain data models, address scalability, and discuss trade-offs. For each architectural decision, connect it to business metrics like conversion rates, average order value, or customer retention. Be prepared to discuss how your architecture handles e-commerce-specific challenges like inventory consistency across channels, cart abandonment recovery, order fulfillment workflows, and personalization at scale. Show awareness of both technical performance metrics (response times, throughput) and business KPIs (cart conversion, search relevance) to demonstrate that you can translate business needs into technical solutions.
