Interview Prompt
A people-analytics team logs one reading per department metric each quarter, and leadership wants to see whether a department's reporting leans toward the first half of the fiscal year or the second. For each department, show the first-half reading count (quarters Q1 and Q2), the second-half reading count (Q3 and Q4), and the ratio of the two.
