A sample answer to question 1

What does a typical day as an expenses administrator involve, and what makes someone good at it?

Most days start with the approval queue in the expenses system, checking which claims have cleared line-manager approval and are ready for audit. I review each against the travel and expenses policy, match receipts to amounts, confirm cost codes and VAT, and either approve for the weekly payment run or return the claim with a clear reason. I also reconcile corporate card transactions, answer employee queries by email or phone, and prepare the month-end accrual for unpaid claims. Good administrators are accurate, patient and consistent. You are applying the same policy to everyone from graduates to directors, so you need a polite but firm manner, and you need to spot patterns, such as the same taxi fare claimed twice. Organisation matters too, because claims peak around month-end and pay deadlines are fixed. I also think curiosity helps, as understanding why a rule exists makes it easier to explain it to colleagues.

Common mistake to avoid: Describing it as simple data entry; ignoring the employee-facing side
