What the interviewer listens for
From the rubric Hmmlo uses for this job family.
Reasoning
You break the problem down, pick a metric that fits the question, and point out what could mislead, like seasonality or a tracking change.
Technical accuracy
Correct methods and terms, and you name the assumptions behind them.
Impact
You connect the analysis to the decision it informed and what happened next.
Clarity
A non-technical listener understands what the number means and why it matters.
One tip
Lead with the decision your analysis supported, then explain the method. Interviewers usually care more about the so-what than the query.
