Describe a challenging project

Behavioral Question

Describe one project you worked on that was particularly challenging.

Please cover:

• Context: What was the goal and your role/ownership?
• Why it was challenging: e.g., ambiguous requirements, tight deadline, scale/performance constraints, cross-team dependencies, poor data quality, changing priorities, high reliability bar.
• Actions you took: key technical and non-technical decisions, trade-offs, how you drove alignment, and how you unblocked progress.
• Outcome: measurable results (latency, cost, accuracy, revenue, adoption, reliability) and what shipped.
• Reflection: what you learned and what you would do differently next time.
