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?
