In this guide
Accounts assistant interviews in the UK usually cover the same ground: double entry, bank reconciliations, purchase and sales ledger processes, VAT basics, accruals and prepayments, Excel and the accounting software you've used. Add a few behavioural questions about accuracy and deadlines and a practical test, and that's most interviews. Prepare clear answers to the questions below and you'll be ready for most of them.
The candidates who stand out answer with examples from real books, not definitions from a textbook.
What do interviewers want from an accounts assistant?
Accuracy, reliability and the ability to learn their systems quickly.
The National Careers Service describes the day-to-day work of an accounting technician as processing and paying invoices, recording receipts and payments, preparing ledger balances and monthly accounts, calculating VAT and helping with year-end accounts. That's close to what most accounts assistant roles involve, so expect questions on each of those areas.
Interviewers are also judging whether you'll fit a small team. Finance teams are often two or three people under pressure at month-end. They want someone calm, careful and willing to ask when unsure.
What technical questions will you be asked?
These come up again and again. Sample answers follow.
Explain double-entry bookkeeping. Every transaction affects at least two accounts, with equal debits and credits. If the business pays a supplier £500 from the bank, you debit the supplier (trade payables) and credit the bank. Keep it short and use an example.
What's a bank reconciliation and why does it matter? Matching the business's records to the bank statement and explaining any differences, such as unpresented payments, outstanding lodgements, bank charges or errors. It matters because it catches mistakes and fraud early and confirms the cash figure in the accounts is right.
What's the difference between accruals and prepayments? An accrual is an expense incurred but not yet invoiced or paid, such as electricity used in March but billed in April. A prepayment is an expense paid in advance, such as annual insurance paid in January. Both make sure costs land in the right period.
Talk me through the purchase-to-pay process. Purchase order raised and approved, goods or services received, supplier invoice received, three-way match (order, delivery and invoice), invoice posted to the purchase ledger, approved for payment, paid in a payment run, then supplier statement reconciled.
What do you know about VAT? Cover the basics: output VAT on sales, input VAT on purchases, the difference paid to or reclaimed from HMRC on the return. You might mention that businesses must register once taxable turnover goes over the threshold, which GOV.UK currently lists as £90,000. You won't be expected to be a VAT expert.
What's the difference between a debtor and a creditor? A debtor (trade receivable) owes the business money. A creditor (trade payable) is owed money by the business.
What happens at month-end? Typically: reconcile bank accounts, post accruals and prepayments, check the purchase and sales ledgers against control accounts, post payroll journals, review the trial balance for anything odd, and produce reports. Say you'd expect to follow the team's checklist.
Which software and Excel questions come up?
Expect "Which accounting systems have you used?" Name what you've genuinely used: Xero, Sage, QuickBooks or a larger system. Say what you did in it. "I've used Xero for bank reconciliations and invoice processing" beats "I know Xero".
For Excel, be ready for:
- VLOOKUP or XLOOKUP to match lists
- SUMIF and COUNTIF
- Pivot tables to summarise data
- Basic formatting and sorting
Many employers set a short practical test, often a reconciliation or a list of transactions to post or analyse. Practise reconciling two lists in Excel until you can do it without thinking. If the test is timed, don't panic about finishing. Show your method clearly, label your workings and flag anything you couldn't resolve. Interviewers often care more about how you approach it than whether every item is cleared.
What behavioural questions should you prepare for?
These test how you work, not what you know. Prepare short stories for:
- A time you spotted an error
- A time you worked to a tight deadline
- A time you dealt with an unhappy supplier or customer
- How you make sure your work is accurate
- How you prioritise when several things are urgent
Use a simple structure: what was happening, what you did, what the result was. Keep each answer under two minutes.
For "how do you make sure your work is accurate?", name real habits: checking totals back to source documents, reconciling before moving on, using checklists, asking someone to review anything unusual.
How do you answer with little or no experience?
Use what you have, honestly. Studies count, especially if you can talk through a real exercise in detail. So do previous jobs involving money or accuracy: cashing up, stock counts, processing refunds, handling customer accounts.
But be aware of the limit. Interviewers ask follow-up questions. "You've done reconciliations? What was the most common difference you found, and how did you clear it?" If your only reconciliations were on training data, that's a hard question to answer well.
Real experience fixes this. For example, someone who has reconciled live bank feeds for small business clients can talk about duplicate transactions, missing receipts and timing differences from memory. That kind of detail makes interviewers relax.
Your CV shapes the interview too. An accounting CV with no experience tends to get generic questions, because there's little to ask about. A CV that lists real tasks ("reconciled three client bank accounts weekly in Xero", for example) gets specific questions, and specific questions are easier to answer well. Before every interview, reread your CV and prepare a two-minute story for each line.
If you're still looking for roles, our guide to accounts assistant jobs covers where to apply, and bookkeeper jobs is a good parallel option.
What should you ask at the end?
Always ask something. Good options:
- "What does month-end look like here, and what would my part be?"
- "Which system do you use, and how would I be trained on it?"
- "What does a good first three months look like in this role?"
They show you're thinking about doing the job well from the first week.

Frequently asked questions
What questions are asked in an accounts assistant interview?
Expect questions on double entry, bank reconciliations, the purchase-to-pay process, VAT basics, accruals and prepayments, and the software you've used, such as Xero or Sage. You'll also get behavioural questions about accuracy, deadlines and handling difficult suppliers or customers. Many employers add a short Excel or bookkeeping test.
How do I explain a bank reconciliation in an interview?
Say it's the process of matching the business's cash book or accounting records against the bank statement, then explaining any differences. Common differences include unpresented payments, outstanding lodgements, bank charges and errors. Finish by saying the goal is a reconciled balance with every difference explained and cleared or followed up.
What Excel skills do I need for an accounts assistant job?
At minimum: SUM, basic formulas, sorting and filtering, and simple formatting. Most employers also expect VLOOKUP or XLOOKUP, SUMIF and pivot tables. Being able to reconcile two lists in Excel and spot differences quickly is a very practical skill to show in an interview or test.
How do I answer accounts assistant interview questions with no experience?
Use examples from your studies, previous jobs that involved money or accuracy, and any real bookkeeping you've done. Be honest about what you've done in practice versus in training. Real experience on live books gives you much stronger answers, because interviewers can ask follow-up questions and you can answer them confidently.
