Describe a time you made a significant financial error that had a material impact on reporting or operations. What was the error, how did you identify it, what steps did you take to rectify it, and what specific controls or process improvements did you implement to prevent recurrence?

Employ the STAR method: Situation (briefly set the scene of the error), Task (outline your responsibility), Action (detail identification, rectification, and stakeholder communication), and Result (quantify impact, lessons learned, and implemented preventative controls/process improvements like enhanced reconciliation, automated checks, or peer review protocols). Focus on systemic changes.

In a previous role as a Senior Financial Accountant, I once misposted a large intercompany loan repayment, debiting the wrong subsidiary's cash account and overstating their balance by $2.5 million. This created a material discrepancy in the consolidated cash position and affected intercompany reconciliations. I identified the error during the month-end bank reconciliation process when the subsidiary's cash balance did not tie to the bank statement. I immediately corrected the journal entry, reversing the incorrect posting and re-entering it accurately. I then communicated the correction and its impact to the Treasury and Consolidation teams. To prevent recurrence, I collaborated with the GL team to implement a new automated validation rule for intercompany transactions, requiring matching subsidiary codes on both sides of the entry. Additionally, I introduced a mandatory peer review for all high-value intercompany journal entries before posting, ensuring a second set of eyes on critical transactions.
