Give me an example when you had to debug a data pipeline issue
Asked in the interviewer1 - technical assessment stage. Explain how you identified the failure, narrowed the possible causes, coordinated with others, and restored reliable data. The interviewer is probing for structured problem-solving, ownership, judgment under uncertainty, and clear communication with stakeholders. A strong response should use one specific incident, distinguish symptoms from root cause, explain the evidence behind each debugging step, and describe both the immediate fix and the prevention work that followed.
