Eight Finance Assistant interview questions, and what the interviewer is thinking

1. What do you think a typical day looks like for a finance assistant?

Why they ask: They want to check you understand the routine, high-volume nature of the job before they hire you.

2. Walk me through how you would process a purchase invoice, from it arriving in the inbox to the supplier being paid.

Why they ask: This is the core process in most finance assistant jobs, so they want to see you know each control step.

3. If the business bought office supplies for £120 including VAT on credit, what entries would you post?

Why they ask: A quick practical test of whether your double-entry knowledge works on a real transaction.

4. How would you allocate a customer receipt in the bank when the amount doesn't match any single invoice?

Why they ask: Unallocated cash is a daily headache for finance teams, and they want to know you can resolve it methodically.

5. You're preparing the supplier payment run and notice that one invoice on the list hasn't been approved. What do you do?

Why they ask: They're checking you respect authorisation controls even under time pressure.

6. How would you manage and reconcile a petty cash float?

Why they ask: Many finance assistant roles still look after petty cash, and it is a classic area for errors and misuse.

7. What checks would you make before processing a staff expenses claim?

Why they ask: Expenses are frequently abused, so they want to see you apply policy consistently.

8. Tell me about a time you processed a high volume of transactions accurately under time pressure.

Why they ask: Accuracy at volume is the heart of this role, so they want real evidence.

A sample answer to question 1

What do you think a typical day looks like for a finance assistant?

Most days start with the bank. I'd download or check the bank feed, match receipts and payments, and flag anything I can't identify. After that it's usually processing: logging purchase invoices, getting them approved, raising sales invoices, and coding expenses claims. There's a steady stream of queries in between, such as a supplier chasing a payment, a manager asking whether an order has been invoiced, or a customer wanting a copy of a statement. Some days have a fixed task attached, like preparing the weekly payment run for approval or updating the aged debtors report before a credit control meeting. Towards month-end the focus shifts to supporting the accountants with reconciliations, accrual listings and tidying suspense items. What ties it together is accuracy and keeping things moving, because if the basics are late or wrong, everything further up the chain, from management accounts to VAT returns, is affected.

Common mistake to avoid: Describing it as purely data entry; Ignoring the query-handling side of the job
