I had a decent answer prepped for this but rambled a bit on the context before getting to my actual contribution.
Choose a project that highlights cross-functional collaboration and stakeholder management, and structure your answer using a clear narrative arc: context, challenge, action, and result. Focus on your specific contributions and how you aligned different teams to achieve a successful outcome.
Pro tip: Quantify the impact of your project and explicitly mention how you navigated conflicting priorities or feedback from stakeholders, as DoorDash values engineers who can drive alignment and deliver results.
Briefly describe the project, its goals, and why it mattered to the business or users. Mention the teams and stakeholders involved.
Clearly state your specific responsibilities and how you contributed to the project. Highlight any leadership or coordination you did across functions.
Explain a key obstacle related to cross-functional alignment or stakeholder management, such as conflicting priorities or communication gaps.
Walk through the steps you took to overcome the challenge, emphasizing collaboration, communication, and any trade-offs you negotiated.
Conclude with the results: metrics, impact, and what you learned. Mention any positive feedback from stakeholders or improvements in team processes.

This one tripped me up more than it should have.
Choose a real, non-trivial mistake with clear impact, but one that you owned and fixed. Structure your answer with STAR, emphasizing root cause analysis and the systemic change you made to prevent recurrence. Keep the focus on learning and growth, not blame.
Pro tip: Pick a mistake where you caught it yourself or proactively surfaced it—this shows ownership and integrity. Avoid mistakes that suggest carelessness or ethical lapses; instead, choose one that reveals a gap in process or a wrong assumption you corrected.
Describe the project, your role, and the situation in 1-2 sentences so the interviewer understands the stakes without unnecessary detail.
Clearly state what you did wrong and quantify the impact (e.g., downtime, data loss, delayed release) to show you understand consequences.
Walk through how you investigated the mistake—what you discovered about why it happened (e.g., missing test, faulty assumption, communication gap).
Explain how you resolved the immediate issue and what systemic changes you implemented to prevent recurrence (e.g., added tests, improved monitoring, changed process).
Summarize the key lesson learned and how it has changed your approach since, tying it to broader engineering principles like resilience or observability.

Easier to answer but I second-guessed which project to use.
Choose a project that demonstrates both technical depth and measurable business impact, ideally one where you made key trade-offs. Structure your answer to highlight the problem, your specific contributions, the trade-offs you navigated, and the quantified outcomes, tying it back to DoorDash's focus on efficiency and customer experience.
Pro tip: Quantify impact using metrics that matter to DoorDash, such as delivery time reduction, order accuracy improvement, or cost savings per delivery. Also, briefly mention what you would do differently next time to show self-awareness and growth mindset.
Briefly describe the project, your role, and the team size. Explain why it mattered to the business or users.
Discuss the technical challenges and the key decisions you made, including alternatives considered and why you chose your approach.
Quantify the outcomes using relevant metrics (e.g., latency reduction, conversion increase, cost savings) and connect them to business goals.
Explain how you led or contributed to the team, overcame obstacles, and influenced stakeholders.
Share what you learned and how you would approach it differently, demonstrating growth and self-awareness.
