- Accrual accounting
- Accrual accounting is a method of keeping books in which income is recorded when it is earned and expenses when they are incurred, whatever the date cash moves.
- Invoice
- An invoice is a document a seller sends to a buyer that lists what was supplied, the amount owed and the payment terms, and it is the trigger for the buyer to pay.
- Three-way match
- A three-way match is a check made before a supplier invoice is paid, in which the purchase order, the record of goods received and the invoice are compared and any difference is resolved first.
- Bank reconciliation
- A bank reconciliation is a comparison of a company's own cash records with its bank statement, listing the timing differences and errors that explain why the two balances differ.

What do accounting and finance-admin interviews test?
These interviews test three habits: getting the numbers right, following the controls, and explaining the result in plain words. The Bureau of Labor Statistics (BLS) says accountants and auditors check financial statements for accuracy and compliance, calculate taxes owed, review accounting systems and watch for fraud risks, and organise, analyse and maintain financial records (BLS Occupational Outlook Handbook, modified 27 August 2026). The same page counts about 1,595,200 jobs in 2025, and 5% growth from 2025 to 2035. Entry usually needs a bachelor's degree, typically in accounting or a related field.
Purchasing work sits next to accounting, because every purchase ends in a payment. The BLS counts about 604,400 purchasing managers, buyers and purchasing agents in 2025, with 6% projected growth from 2025 to 2035. Buyers evaluate suppliers on price, quality and delivery speed, negotiate contracts, and keep records of purchases, costs, deliveries and inventory (BLS purchasing page, modified 27 August 2026). Purchasing managers also write procurement policies that help staff meet ethical standards and avoid conflicts of interest.
Interviewers in all three roles ask the same kinds of question. Technical questions check that you know the mechanism. Scenario questions give a messy case, such as a duplicate invoice, and ask what you do first. Fit questions ask about accuracy under deadline pressure. Fit questions are answered with short stories from your own work, the format of behavioral interviews, and the first of them is your answer to tell me about yourself.
Knowing it is half the job. Saying it is the other half.

Start Free Trial →Why does the accounting method change the profit you report?
The accounting method decides in which period a sale or a cost is counted. The Internal Revenue Service (IRS) says that under the cash method you generally report income in the tax year you receive it, and under the accrual method you generally report income in the tax year you earn it, regardless of when payment is received (IRS Publication 538, 01/2022). Expenses follow the same split: the cash method counts them when paid, the accrual method when incurred.
Worked example, illustrative 1: a business invoices a customer 1,000 on 20 December for work finished that month, and the customer pays on 15 January. A contractor does 400 of work for the business in December, bills it on 28 December, and is paid on 10 January. The business pays December rent of 300 on 1 December.
On the accrual method, December shows revenue of 1,000 less costs of 700 (the contractor's 400 and the rent of 300), a profit of 300. On the cash method, December shows only the rent paid, a loss of 300, and January shows cash received of 1,000 less 400 paid, a profit of 600. Check: both methods total 300 over the two months, so the method moves profit between periods and does not create or remove any.1
| Item (illustrative) | Accrual method, December | Cash method, December | Cash method, January |
|---|---|---|---|
| Revenue or cash in | 1,000 | 0 | 1,000 |
| Costs or cash out | 700 | 300 | 400 |
| Result | 300 profit | 300 loss | 600 profit |
The timeline below puts each event in its month, which is the quickest way to explain the gap aloud.
A good interview answer says why neither view is wrong. Accrual shows how the business performed in the period, and the cash view shows whether money is actually in the bank. A profitable business that waits for customers to pay can still run short of cash, so accountants track both. The Securities and Exchange Commission (SEC) beginners' guide makes the related point that the balance sheet shows assets, liabilities and shareholders' equity at one moment, while the income statement shows revenue earned over a period (SEC, reviewed February 2017).
Text description of the diagram
- Accrual counts the 1,000 invoice and the 400 contractor bill in December.
- The cash method counts the 1,000 on 15 January and the 400 on 10 January.
How does billing turn a sale into cash?
Billing turns a sale into a request for payment, and the chain has four links: the order, the delivery, the invoice and the receipt of cash. A billing specialist owns the last two: the invoice and the follow-up until the cash arrives. The invoice states what was supplied, the amount and the payment terms, and the money owed before it is paid sits on the books as accounts receivable. Accounts receivable is the amount customers owe the company. Accounts payable is the mirror image: the amounts the company owes its suppliers.
Many billing errors come from a mismatch earlier in the chain, such as a price that differs from the contract or a delivery that was never recorded. That is why interviewers ask what you check before sending an invoice. A strong answer names three checks: the price against the agreed terms, the quantity against the delivery record, and the customer details against the account. Then it names what you do when a customer disputes a line: log the dispute, send only the undisputed part for payment if the terms allow, and give a date for the answer.
How does a three-way match stop a wrong payment?
A three-way match stops a wrong payment by comparing three documents before any money moves. The purchase order shows what the company agreed to buy, the goods-received record shows what actually arrived, and the supplier invoice shows what the supplier claims is owed. If all three agree, the invoice is paid. If they differ, the difference is resolved first.
Worked example, illustrative 1: a purchase order is for 100 units at 12 each. Only 90 units arrive, but the invoice bills all 100 and asks for 1,200. The goods-received record supports 90 units, which is 1,080. The match pays 1,080 or holds the invoice, and 120 goes to the supplier as a query until the missing 10 units arrive or a credit note (a supplier document that reduces what is owed) is issued.
Text description of the diagram
- The goods-received record supports 90 units, which is 1,080.
- The match pays 1,080 or holds the invoice, and 120 goes to the supplier as a query.
Services have no delivery to count, so a buyer substitutes a different proof of receipt, such as a signed timesheet or a completion confirmation. Mention that in an interview, because it shows you know why the control exists, which is to pay only for what the company received.
What is a bank reconciliation and why do accountants do it?
A bank reconciliation explains why the balance in the company's books differs from the balance on the bank statement. The usual causes are timing: a deposit recorded but not yet shown by the bank, a cheque issued but not yet cashed, and a bank fee the company has not yet booked.
Worked example, illustrative 1: the bank statement shows 5,200. A deposit of 400 is in transit, and a cheque of 250 is outstanding. The adjusted bank balance is 5,200 plus 400 minus 250, which is 5,350. The company's books show 5,365, and a bank fee of 15 has not been recorded, so the adjusted book balance is 5,350. The two agree, so the reconciliation is complete.
If they did not agree, there would be an error to find, and an interviewer will ask how you would search for it: start with the difference, look for a transaction of that exact amount, then for half the difference, which suggests an item posted on the wrong side, and then for a difference divisible by 9, which suggests two digits typed in reverse order.
The role question lists
Each role below builds on the ideas above and adds the questions specific to it. Pick the one that matches the posting.
Accounting questions for interview: accountant questions and answers
Accountant interviews test the three statements, accrual versus cash, journal entries made at month end to put income and costs in the right period, reconciliations, the month-end close (the routine that finishes the books for a month) and what you do when a number will not match. Interviewers use these questions to see whether you can both do the mechanics and explain them. The usual trap is reciting a definition without a small number to show you can apply it, so practise the December example above until you can say it in under a minute. For a manager role, expect questions beyond the mechanics too, and the accountant interview questions and answers work through each one.
Billing specialist interview questions and answers
Billing specialist interviews cover invoicing, collections, disputes and accuracy: what you check before an invoice goes out, how you handle a late payer, and how you treat a customer who disputes a charge. Interviewers want evidence of care and of calm with customers. The trap is promising speed over accuracy, so say that you would rather hold an invoice for one check than send a wrong one. Expect scenario questions about a duplicate invoice or a price that differs from the contract, and answer each with what you check first and whom you tell. Use the accounts receivable idea from this page as your frame, and the billing specialist interview questions and answers practise it.
Procurement manager interview questions and answers
Procurement manager interviews cover sourcing, negotiation, supplier evaluation, contracts and policy. The BLS says buyers evaluate suppliers on price, quality and delivery speed, so expect questions that make you trade the three off. Another common theme is conflicts of interest, which a manager must prevent through policy. The trap is treating price as the only criterion. The three-way match on this page is a control a buyer should be able to explain, so be ready to walk through the purchase-order example above and say what you do when the goods arrive short. The procurement manager interview questions and answers cover this ground.
Questions interviewers ask in finance-admin roles
Each question below uses an idea from this page, and the one-line answers are starting points. Fuller answers on accounting questions, on invoicing and dispute questions and on supplier and matching questions sit with each role.
- What is the difference between cash and accrual accounting? Cash records money when it moves, accrual records income when earned and costs when incurred.
- Why would a profitable company run short of cash? Customers pay after the sale, so cash can arrive later than the profit is recorded.
- What do you check before sending an invoice? The price against the terms, the quantity against the delivery record, and the customer details.
- What is a three-way match? A comparison of the purchase order, the goods-received record and the invoice before payment.
- You find the same invoice paid twice. What do you do? Stop any further payment, tell your supervisor, then ask the supplier for a refund or a credit note.
- How do you reconcile a bank account? List the timing differences, adjust both sides, and investigate any remaining difference.
- Tell me about a mistake you made with numbers. Name it, how you found it, and what check you added afterwards.
Open with a short answer to tell me about yourself that names one check you added, and close with your own questions to ask the interviewer. Each round of an interview loop can mix the three kinds of question above.
Follow-up questions
How do I prepare for an accounting interview?
Work the three examples on this page by hand until you can say each aloud, learn the accounting equation (assets equal liabilities plus equity), and prepare one story about catching an error. Then practise the accountant interview questions, or the ones for your role.
What is the difference between accounts payable and accounts receivable?
Accounts receivable is what customers owe the company, and accounts payable is what the company owes its suppliers. A billing specialist works mostly on the first, and a buyer or payables clerk on the second; billing specialist interview questions cover the first in interview form.
Do I need a degree for a procurement role?
Usually, though not always. The BLS says buyers and purchasing agents typically need a bachelor's degree for entry-level positions, and that a high school diploma or the equivalent may be sufficient for some positions (BLS purchasing page, modified 27 August 2026). Procurement manager interview questions show what a hiring manager asks once you are through the door.
What should I bring to a finance-admin interview?
Bring a clean copy of your résumé, two or three examples where a check you made caught a mistake, and questions about the team's month-end routine; more questions to ask the interviewer help here. Leave out any real company figures from past jobs.
- These interviews test accuracy, controls and plain-words explanation.
- Accrual counts income when earned; cash counts it when received.
- A three-way match pays for what arrived, not for what was billed.
- A bank reconciliation explains timing differences and exposes errors.
- Pick the role that fits your job, then rehearse aloud.
