This sounds manageable until you realize they're not just listening politely.
Choose a project where you played a central role and can clearly articulate the problem, your decisions, and measurable outcomes. Use the STAR method but emphasize the technical depth: the 'why' behind your choices, trade-offs, and obstacles. Tailor your answer to show impact at scale, given Coupang's large-scale e-commerce environment.
Pro tip: Quantify the impact with metrics (e.g., latency reduction, cost savings, user growth) and explicitly connect your technical decisions to business outcomes. This demonstrates product thinking and aligns with Coupang's data-driven culture.
Briefly describe the project, its goals, and the specific problem you were solving. Highlight why it mattered to the business or users.
State your exact role, the team size, and what you personally owned. Be clear about your contributions versus the team's.
Walk through the key technical choices you made, the alternatives considered, and why you chose your approach. Discuss trade-offs (e.g., performance vs. cost, consistency vs. availability).
Share specific challenges (technical, organizational, or resource-related) and the steps you took to resolve them. Show resilience and problem-solving.
Quantify the outcome with metrics (e.g., reduced latency by X%, increased conversion by Y%). Reflect on what you learned and how you'd approach it differently.
