Accountant interview questions and how to answer them

Common questions for accountant

1. 01

   How do you organize a monthly or quarterly closing when the deadline is tight?

   Don't answer “I work well under pressure”: describe your system. A closing calendar, a checklist, what you get ahead on during the month and how you flag when something slips. They're assessing whether the closing depends on your method or on your overtime.

   “At my last company we closed the month in five business days. The first thing I set up was a closing calendar with tasks and owners: day 1, billing cutoffs and provisions; day 2, bank reconciliations; day 3, depreciation and accruals; days 4 and 5, review and reporting. I work with a checklist of about 40 items, because under pressure memory fails. And I get ahead on everything I can: I keep reconciliations up to date during the month, I don't leave them for the end. When billing ran late, I escalated it on day 2, not day 5: flagging early is what saves the deadline.”

   A bank reconciliation doesn't balance and you've spent an hour without finding the difference. What's your method?

   They want to see an orderly process, not luck. Explain how you narrow it down (the difference figure itself gives clues), how you split the period so you don't review entry by entry and who your usual suspects are. A real case with the exact amount is worth more than all the theory.

   “First I narrow it down: I compare the statement balance with the ledger balance and calculate the exact difference, because the figure already gives clues. If it's a round number, it's usually a missing entry; if it's divisible by 9, there are almost certainly two digits transposed: a 3,540 entered as 3,450. Then I go from the last point where it balanced forward, splitting the period in two so I don't review entry by entry. Once I chased 127.43 euros all morning: it was a bank fee left unrecorded since March. Ever since, I check fees, transfers in transit and grouped receipts first, which account for almost all discrepancies.”

3. 03

   You discover that a journal entry you posted weeks ago is wrong. What do you do?

   They're assessing your honesty before your technique. The correct answer runs through flagging it early with the impact measured and correcting it in a documented way, distinguishing whether the period is open or closed. Any hint of covering it up or “shuffling it around” rules you out.

   “First, don't cover it up. It happened to me with an 18,000-euro invoice I posted as outside services when it was a fixed asset: I caught it myself reviewing the quarter's depreciation. I told my manager the same day with the impact calculated: which accounts it affected, by how much and whether it touched an already-filed period. Since the quarter was still open, I corrected it with a documented reclassification entry, referencing the original entry and a note on the reason. If it had affected a closed fiscal year, I'd have gone through account 113 as the chart of accounts requires. A mistake owned in time costs one entry; hidden, it costs trust.”

4. 04

   Accounting and tax rules change every year. How do you keep up to date?

   They won't ask you to recite the chart of accounts: they want to know whether you'll learn about changes before a deadline catches you out. Describe your concrete sources, your update routine and a recent regulatory change you've actually applied.

   “I don't try to know it all by heart: I try to learn in time about what changes. I'm subscribed to the AEAT updates and a couple of firm newsletters, and I set aside half an hour on Fridays to go through them. When there's a big change, like mandatory e-invoicing or Veri*factu, I take a short course and prepare an internal note on what affects us. At my previous company that let us adapt the billing series two months before the deadline, no scares. And for the day-to-day, my own tax calendar: forms 303, 111 and 200 with alerts ten days before each due date.”

5. 05

   What accounting software do you know and what exactly do you use it for?

   “Advanced Excel” with no examples says nothing. Name the ERP and the specific modules you've touched, and in Excel the functions you use and for what real task. Prepare for the follow-up: if you say pivot tables, be ready to explain what you built with them.

   “With SAP FI I've worked four years day to day: posting supplier invoices with three-way verification, account reconciliation and closings. At a previous SME I used A3, so I'm comfortable in both worlds. Excel is my analysis tool: pivot tables to review the ledger, XLOOKUP to cross the bank statement with the ledger, and a reconciliation template that cut the monthly tick-off of the main account from three hours to forty minutes. I don't use it to keep the books, but to check them: the ERP records and Excel lets me ask questions of the data.”

6. 06

   Explain a figure or a report to someone with no financial background, as you would to a manager.

   They're assessing whether you translate or whether you recite. What they're looking for is that you start from the decision the other person has to make, use everyday comparisons and don't hide behind jargon. A real example of the classic “there's profit but no cash” works very well.

   “The manager at my last company struggled to understand why there was profit but no cash. I explained it without a single accounting term: we'd billed 90,000 euros in the quarter but collected 60,000, because two big clients paid at 90 days, and meanwhile payroll and suppliers went out every month. I compared it to his personal account: you can have a salary promised and the bank at zero. With that he decided to bring collections forward and take out a line of credit. My rule is to start with the decision the other person has to make, give them the three figures that support it and save the jargon for when they ask for it.”

7. 07

   You're going to handle sensitive information: salaries, margins, customer data. How do you manage confidentiality?

   It's not enough to say “I'm discreet.” Tell a real situation in which someone asked you for information that wasn't theirs to have and how you resolved it without creating conflict, and add your practical habits for protecting information.

   “In accounting you see salaries, margins and layoffs before they're announced, and that only works with one rule: information leaves me only toward whoever is authorized, no matter who the question comes from. It's happened to me: a salesperson at the company asked me for the margin we had with a specific client to adjust his next offer. I explained without drama that this data was authorized by the finance department, I told my manager the same day, and the part he could use reached the salesperson through his boss. I also apply it practically: screen locked when I get up, payroll files password-protected and no sensitive figures over WhatsApp. Discretion isn't a bonus of the job: it's the condition for being allowed to see the numbers.”

8. 08

   An invoice reaches you that seems irregular or you spot a suspicious expense. What do you do?

   They're measuring your judgment and your prudence at once: neither posting without looking, nor mounting an accusation. The sequence they expect is to verify with documentation, leave a written trail and escalate through the right channel. Citing concrete signs of an irregular invoice earns a lot of points.

   “I spotted a maintenance invoice that grated on me for three details: an amount just below the second-signature threshold (4,900 euros, with the limit at 5,000), a generic description (“miscellaneous services”) and a tax ID that, when I checked it in the AEAT registry, had been deregistered for months. I didn't post it or accuse anyone: I gathered the invoice, the purchase order and the contract, documented the three inconsistencies and escalated it in writing to my finance manager. It turned out to be a duplicate supplier with outdated data, not fraud, but the process is the same: verify, document and escalate through the right channel, never settle it in whispers.”

Many of these questions are the “tell me about a time when…” type. To structure those answers around a clear story, use the STAR method.

Tips to stand out

• Bring three real cases ready with their figures: a discrepancy you solved, a tricky closing and a mistake handled well. With those three you cover half the interview.
• When you talk about software, anchor each tool to a concrete task. “I use SAP” says nothing; “I posted supplier invoices with three-way verification in SAP FI” does.
• If they ask you a regulatory detail you don't know, say so and explain where you'd check it. In accounting, making up the answer is the worst possible signal: reliability is worth more than memory.
• Practice the answers out loud with the AI before the interview. Explaining a discrepancy or a correcting entry fluently doesn't come from reading: it comes from rehearsing how you tell it when they follow up.
