Choose a project with clear business impact and explain it in layers: start with a high-level analogy that a non-expert can grasp, then gradually add technical depth only as needed. Focus on the 'why' behind your decisions and trade-offs, and explicitly invite questions to ensure understanding.
Pro tip: Use a relatable analogy (e.g., 'like a postal service for data') to anchor the problem, then map technical components to that analogy. This makes complex ideas accessible and shows you can communicate with cross-functional partners—a key skill at Plaid.
Briefly describe the project's goal and why it mattered, using a simple analogy to make the problem relatable to a non-expert. Avoid jargon and focus on the user or business impact.
Outline the core challenge, including any technical, time, or resource constraints. Highlight why it was non-trivial and what made it interesting.
Describe the options you considered, why you chose your approach, and the trade-offs involved (e.g., speed vs. scalability, cost vs. performance). Use the analogy to explain technical concepts.
Quantify the outcomes (e.g., reduced latency by X%, saved Y dollars, improved user engagement). Connect the results back to the initial problem and business goals.
Check for understanding by pausing and asking if the explanation makes sense. Offer to dive deeper into any area and relate technical details to the analogy when asked follow-up questions.
