Behavioral: Most Impactful Recent Project (Software Engineer, Onsite)

Prompt

Walk me through your most impactful recent project. Describe:

1. The problem you were solving and why it mattered.
2. Your role and specific contributions.
3. How you measured success (metrics, targets, and validation method).
4. A deep dive into one technical decision: options considered, trade-offs, and why you chose your approach.
5. A risk or failure you encountered and how you handled it.
6. What you would do differently now.
7. If you don’t recall a detail in the moment, how you would quickly rediscover the context and validate your memory before making decisions.

Use a clear structure (e.g., STAR: Situation, Task, Actions, Results), be concrete with metrics, and demonstrate ownership and learning.
