Explain Project Ownership and Collaboration with Colleagues

Company: Lyft

Role: Software Engineer

Category: Behavioral & Leadership

Difficulty: medium

Interview Round: Onsite

Discuss a past project you are proud of and explain how you worked with colleagues to move a project forward. You may use the same project for both parts if it supports both answers. Use your own experience and distinguish your contribution from the team's work. ### Part 1 — The project you are proud of What problem did the project address, what did you personally own, and why does the result make you proud? Explain a difficult decision rather than only listing the technologies used. #### What This Part Should Cover - The original problem and why it mattered to the people using or operating the system. - Your decisions, their tradeoffs, and evidence supporting the outcome. - A concrete limitation or lesson that remains even if the project succeeded. ### Part 2 — Moving the work forward with colleagues Describe a dependency, disagreement, or coordination problem in a project. How did you work with the people involved to reach a decision and keep the work moving? #### What This Part Should Cover - The different responsibilities or constraints that made collaboration necessary. - The actions you took to clarify ownership, resolve the issue, and follow through. - Credit for others' contributions and an explanation of what you would change next time. ### What a Strong Answer Covers - A coherent account that separates personal ownership, team decisions, and outcomes. - Enough detail about a technical or delivery decision to support deeper questions. - Honest evidence and reflection, without invented metrics or claiming other people's work. ### Follow-up Questions - Which decision in the project would you revisit with what you know now? - How did you tell whether the collaboration issue was actually resolved rather than merely deferred?
