Clarifying Questions (3 minutes)

• Given the timing, I suspect the update might be directly related. Has there been any change in the types of resumes or job descriptions being processed since the update?

Why it matters: This could indicate if the issue is with the update itself or changes in input data. Expected answer: No significant changes in input data. Impact on approach: If confirmed, focus on the update itself rather than data quality.

• Considering user segments, are we seeing this accuracy decline across all industries or job types, or is it concentrated in specific areas?

Why it matters: This helps isolate whether the issue is universal or specific to certain use cases. Expected answer: The decline is relatively uniform across segments. Impact on approach: If uniform, look at core algorithm changes; if specific, investigate those segments' unique characteristics.

• Regarding performance metrics, has there been any change in how accuracy is measured or reported since the update?

Why it matters: Ensures we're comparing apples to apples in our analysis. Expected answer: No changes in measurement methodology. Impact on approach: If confirmed, we can rule out measurement issues and focus on actual performance decline.

• Thinking about system changes, were there any infrastructure or data pipeline modifications concurrent with the software update?

Why it matters: Helps identify if the issue is solely software-related or involves broader system changes. Expected answer: No significant infrastructure changes. Impact on approach: If confirmed, narrow focus to software update; otherwise, broaden investigation to include system-wide changes.
