This one sounds easy until you're actually in it and realize your story is sprawling all over the place.
Choose a project that demonstrates both technical depth and cross-functional collaboration, ideally with measurable impact. Structure your answer using a clear narrative arc: context, challenge, action, result, and learning. Emphasize your personal contributions and the trade-offs you navigated.
Pro tip: Quantify the impact with metrics (e.g., latency reduction, cost savings, user growth) and explicitly connect your technical decisions to business outcomes. DoorDash values engineers who understand the 'why' behind the work.
Briefly describe the project, its goal, and why it mattered to the business or users. Mention the team size and your role.
Explain the hardest technical challenges, such as scalability, real-time constraints, or integration issues, and why they were non-trivial.
Focus on what you personally did: design decisions, code you wrote, trade-offs you made, and how you collaborated with others.
Describe how you worked with product, design, data science, or other teams to align on requirements and deliver the solution.
Share measurable results (e.g., performance improvements, cost savings, user engagement) and what you learned or would do differently.

Conflict questions always feel like a trap to me.
Use the STAR method to structure your answer, focusing on a professional disagreement that you resolved constructively. Emphasize how you listened to the other person's perspective, communicated your own, and worked together to find a solution that benefited the team and the product. Conclude with the positive outcome and what you learned.
Pro tip: Choose a disagreement where you were not clearly right from the start; showing that you can be persuaded by good arguments demonstrates humility and strong collaboration skills. Also, highlight how you prioritized the team's goals over being right.
Briefly describe the situation, your role, and the colleague involved, focusing on the technical or project-related nature of the disagreement.
Clearly state what the conflict was about, such as differing technical approaches, priorities, or interpretations of requirements, without blaming the other person.
Detail how you addressed the conflict: actively listening, seeking to understand their perspective, and communicating your own viewpoint with data or reasoning.
Explain how you reached a resolution, whether through compromise, experimentation, or escalation, and emphasize collaboration.
Conclude with the positive results, such as improved solution, stronger relationship, or process improvements, and what you learned from the experience.
