Feedback and Continuous Improvement Questions

This topic assesses a candidate's approach to receiving and acting on feedback, learning from mistakes, and driving iterative improvements. Interviewers will look for examples of critical feedback received from managers peers or code reviews and how the candidate responded without defensiveness. Candidates should demonstrate a growth mindset by describing concrete changes they implemented following feedback and the measurable results of those changes. The scope also includes handling correction during live challenges incorporating revision requests quickly and managing disagreements or design conflicts while maintaining professional relationships and advocating for sound decisions. Emphasis should be placed on resilience adaptability communication and a commitment to ongoing personal and team improvement.

Describe your process for root cause analysis when monitoring shows a sudden degradation in model precision. Explain how you would do data slicing, timeline reconstruction, code and infra checks, feature pipeline inspection, and stakeholder communication to prioritize fixes.

Walk through an iterative troubleshooting process you used to reduce model drift in production. Describe monitoring signals you used, how you diagnosed root cause (data vs concept drift vs pipeline change), the remediation steps you took (feature fixes, retraining, monitoring), and how you validated improvements after deployment.

Give an example of a small change you made after receiving feedback (for example: switching loss function, adding early stopping, quantizing model, or enabling caching). Explain why this change was suggested, how you implemented it, and the measurable improvements obtained in offline and/or online metrics.

Describe a time you received critical feedback on an ML model, training pipeline, or code during a review. Include the specific feedback, your immediate reaction, the concrete changes you implemented, measurable results after the change (metrics, latency, or production impact), and what you learned that you applied to later work.

Design a small experiment to measure the impact of a code refactor on both model performance and CI/CD deployment frequency. Specify the engineering and model metrics you'd collect, the experimental design (A/B, pre-post), statistical tests to apply, and success criteria for merging the refactor.
