How do you ensure data quality in the group reporting package?
A core Group Accounting interview question — asked in analyst and associate interviews across IB, PE, and the Big 4.
THE SHORT ANSWER
Layered controls, preventive and detective. Built into the submission: automated validation rules in the consolidation system (the package can't be submitted until it internally ties — e.g., B/S balances, roll-forwards reconcile, mandatory fields complete). Analytical/detective checks: plausibility review against prior period, budget, and prior year, and review of key ratios and unusual movements (flux analysis with explanations for material variances). Process controls: sub-controller/local-CFO sign-off before submission, four-eyes on manual entries, and IC matching cleared to tolerance. Plus master-data discipline (consistent chart of accounts, entity and currency setup). The aim is to catch errors at source (cheaper and faster) rather than at group review, and to make the submitter accountable for a validated, explained package — not just numbers. Tracking submission quality/timeliness as a KPI reinforces it.
