Summary

Behavioral round at DoorDash for an ML Engineer role. Just the one question but it had a lot of moving parts packed into it.

Questions Asked (1)

Q1

Tell me about a time you had a disagreement with a collaborator. How did you approach the conversation, what was the disagreement about, how did you understand their perspective, and how did you resolve it? What was the outcome, and what would you do differently?

Suggested Approach

Use the STAR method to structure your answer, focusing on a specific disagreement with a cross-functional collaborator (e.g., product manager, data scientist, or software engineer). Emphasize how you actively listened to understand their perspective, used data and experimentation to resolve the conflict, and aligned on a solution that balanced technical feasibility with business goals. Conclude with the measurable outcome and a reflection on what you learned.

Pro tip: Frame the disagreement as a difference in priorities or assumptions, not a personal conflict, and highlight how you used data or a small experiment to test both sides' hypotheses. This shows you can turn conflict into a constructive, evidence-based decision-making process—a key skill at DoorDash where ML solutions must balance model performance with business impact.

1. Set the context and disagreement

Briefly describe the project, your role, and the collaborator's role. Clearly state the disagreement in one sentence, focusing on the technical or strategic difference (e.g., model complexity vs. latency, feature prioritization).

2. Explain your approach to the conversation

Describe how you initiated a private, respectful discussion. Mention that you sought to understand their perspective first by asking open-ended questions and acknowledging their concerns.

3. Show how you understood their perspective

Summarize their viewpoint and the underlying interests (e.g., they were worried about user experience or engineering resources). Explain how you validated their concerns and found common ground.

4. Describe the resolution process

Detail the steps taken to resolve the disagreement, such as running a quick A/B test, building a prototype, or consulting a third party. Emphasize data-driven decision-making and compromise.

5. Share the outcome and reflection

State the measurable result (e.g., improved model accuracy, reduced latency, successful launch). Reflect on what you would do differently, such as involving stakeholders earlier or setting up clearer success metrics.

Key Points to Mention

  • Active listening and empathy: how you made the collaborator feel heard
  • Data-driven approach: using metrics, experiments, or prototypes to resolve the disagreement
  • Cross-functional collaboration: working with product, engineering, or business teams
  • Business impact: how the resolution benefited the user or company (e.g., improved delivery estimates, reduced costs)
  • Learning and growth: what you would do differently next time, showing self-awareness
  • Alignment on goals: how you refocused the conversation on shared objectives
