Conflict & Collaboration

1. Describe a time you disagreed with a colleague on a technical approach. How was the conflict resolved? Conflict

Focus: Professionalism, objectivity, and data-driven decision-making. (Demonstrates "Have Backbone; Disagree and Commit").

Action: We agreed that personal opinions shouldn't dictate the architecture. We spent one afternoon building minimal Proof-of-Concepts (POCs) for both approaches and benchmarked the critical performance metric (e.g., latency).
Result: The data clearly favored my colleague's approach for long-term scalability. I immediately endorsed their plan and led the implementation, demonstrating commitment to the project's best interest over personal ego.

2. Give an example of a time you received critical feedback. How did you handle it? Coachability

Focus: Growth mindset and ability to seek out improvement, not defensiveness.

Situation: During a code review, my manager pointed out that my module lacked sufficient unit testing, creating a potential technical debt (Task: improve testing rigor).
Action: I first thanked them for the honest feedback. I then scheduled a follow-up to understand the gaps. I spent the next two weeks researching TDD (Test-Driven Development) and implemented a **100% test coverage policy** for my new features.
Result: My subsequent module reviews required zero rework for testing. I also created a short internal guide on TDD, sharing the learning with the team.

3. Describe a time you identified a problem outside of your scope and took the initiative to fix it. Initiative

Focus: Ownership and identifying operational inefficiencies that impact the wider team.

Situation: The team's deployment pipeline took 45 minutes, frustrating developers and slowing velocity. This wasn't my assigned task (Task: speed up the build time without sacrificing safety).
Action: I researched parallelization techniques for Jenkins/GitHub Actions. I dedicated 10% of my time over two sprints to refactor the pipeline scripts, implementing parallel testing and optimized image caching.
Result: I reduced the total build time from 45 minutes to **12 minutes**. This saved the 10-person team approximately 5 hours of idle time per day, resulting in a measurable increase in deployment frequency.

4. Tell me about a time you mentored someone or delegated a critical task to a junior team member. Leadership

Focus: Developing others and fostering trust, not just dumping work.

Situation: A junior engineer was struggling with a complex database query optimization, a critical step for our launch (Task: ensure the task was completed correctly while building the junior engineer's skill).
Action: I broke the task into three manageable parts. I provided them with key resources (documentation on explain plans and indexes) and scheduled daily 15-minute check-ins. I emphasized **guidance** and **review**, not taking the keyboard.
Result: The engineer successfully delivered the optimized query ahead of schedule. More importantly, they gained the confidence and technical skill to handle similar database challenges independently in the future.
