Accenture: Apply approved salary updates and remove departed employees from the employee table.
The HR operations team has exported three files from the employee system ahead of the next payroll run: the current employee records, a list of approved salary updates, and a list of departure notices. They want the employee table brought up to date.

Assume this data comes directly from the HR system and hasn't been cleaned, so review it carefully before relying on the numbers. When something looks off, work out what it is and decide how to handle it; when a definition or a final decision is genuinely ambiguous, choose a reasonable option and explain why. There's often more than one valid way to compute a result, so explain the approach you take and the reasoning behind your choices.
What's assessed: your results, and how clearly you explain what you see in the data and justify the choices you make.
