Split an employee ID into department and hire year
The department and hire year are baked into the ID — once you know where to cut.
Task:
You work in HR analytics and need a headcount report broken down by department and hire year. Employee IDs follow a fixed pattern: three letters for the department, a dash, the four-digit hire year, a dash, then a sequence number. Split each ID: put the department in column C and the hire year in column D.
