What Accountant Interviews Actually Test

Who's actually asking the questions

It depends which side of the profession you're on, and the interview is shaped by that.

If you're interviewing for a practice role — audit, tax, or general practice at a firm with a training contract attached — you'll usually meet a manager or senior manager first, sometimes with a partner in a later round if the role is client-facing. They will have your CV and probably your ACA or ACCA exam record in front of them, and they will ask about specific engagements you've worked on, not generic accounting theory.

If you're moving into industry — a financial accountant, management accountant, or FP&A role inside a company — the first interview is usually with the hiring manager (often the Financial Controller or a finance business partner), sometimes alongside someone from HR who asks the values-fit questions and then leaves the technical ground to the finance person. A second round often includes the CFO or a cross-functional stakeholder you'd actually work with, like someone from operations or sales, especially for business partnering roles.

Graduate schemes at the larger firms add a layer before any human interview: a numerical reasoning test (commonly SHL or similar), sometimes a situational judgement test, and occasionally a recorded video interview. These are filters, not conversations, and they test speed and accuracy under time pressure more than accounting knowledge.

The technical assessment: what actually gets put in front of you

At qualified and part-qualified level, the technical component is rarely abstract theory. It's usually one of these:

• A set of accounts or a P&L with an error in it, and you're asked to find it and explain the impact. This tests whether you actually read numbers or just recite process.
• A short Excel exercise — build a bank reconciliation, a variance analysis, or a simple three-statement model from raw data. Nobody is grading your keyboard shortcuts; they're watching whether your approach is auditable, whether you'd catch your own error, and whether you can explain what you built afterwards.
• A case study conversation built around a set of statutory accounts or management accounts, where you're asked to walk through what you'd query first. This is common in audit interviews and is really a scepticism test: do you go looking for the number that doesn't reconcile, or do you accept the pack as given?
• A verbal walkthrough of a process — close the books, calculate a deferred tax adjustment, explain an accrual versus a provision — done from memory, without notes. This checks whether the concept lives in your head or only in your textbook.

What's tested less often than people expect: standalone recall questions like "define FRS 102" or "what's the difference between IFRS and UK GAAP". Those come up, but usually as a warm-up before the interviewer asks you to apply the standard to a scenario, which is where the real assessment happens.

The questions that are actually probing something

A few questions come up across practice and industry roles precisely because they're hard to fake. Here's what each is really checking.

"Tell me about a time you found a discrepancy that no one else had spotted." This isn't asking for a story. It's testing professional scepticism — whether you go looking for problems or wait for them to be flagged. A strong answer names the specific control that failed (a missing three-way match, a duplicate invoice, a suspense account that hadn't cleared) and what you did once you found it, including who you told and why.

"Walk me through how you'd close the month end if the sales invoice for a major client hadn't been raised yet." This tests judgement about materiality and timing, not the mechanics of an accrual. The interviewer wants to hear you weigh the size of the missing figure against the reporting deadline, and explain what you'd do differently if it were £2,000 versus £2 million.

"How would you explain deferred tax to someone in sales who thinks the P&L number should match the cash tax paid?" This checks communication, which matters more in industry roles than candidates expect, especially business partnering positions where you're translating accounting concepts for non-finance stakeholders on a weekly basis.

"If you disagreed with a partner's or FD's judgement on a provision, what would you do?" Common in ACA and ACCA-track interviews because it goes to the ethical code both bodies examine directly. The interviewer wants to know you'd raise it through the proper channel — not that you'd back down, and not that you'd go over someone's head unnecessarily.

"Talk me through your CV gap" or "why did you leave your last role after eight months?" Given the current market, this comes up more than it used to. It isn't a trick. It's checking whether you can talk about it plainly, without either over-explaining or being evasive, because both read as something to hide.

What a shallow answer sounds like

Someone who has done this job for years can hear a rehearsed answer within a sentence or two. A few patterns that give it away:

• Reciting the STAR structure so mechanically that the situation, task, action and result blur into one paragraph of no specific numbers. "I identified an issue and resolved it efficiently" tells the interviewer nothing. "I found a £40k VAT misclassification in the quarterly return and corrected it before submission" tells them everything.
• Defining a standard instead of applying it. If asked how they'd treat a lease under IFRS 16, a weak answer describes the standard from memory. A strong one asks a clarifying question first — is this a short-term lease, is the underlying asset low-value — because that's what an accountant actually does before making the call.
• Talking about "attention to detail" as a trait rather than describing a specific control they built or checked. Every candidate says they're detail-oriented. The interviewer wants the mechanism: the reconciliation template, the review checklist, the second-pair-of-eyes process.
• Answering "how would you handle a tight deadline" with a story about working late, rather than a story about triaging what could be deferred without breaching a statutory filing date. The second answer shows they understand which deadlines are hard (Companies House, HMRC) and which are internal and negotiable.

What to do with this before the interview

Go back to the advert and find the two or three things it actually asks for — a specific system (SAP, Oracle, Xero, CaseWare), a specific standard (IFRS 15 revenue recognition, FRS 102), a specific process (statutory accounts preparation, VAT returns, group consolidation) — and prepare one real example for each, with a number in it. Not a generic "I'm good at Excel" but the actual model or reconciliation you built and what it caught.

If you're short on interview practice because the applications aren't converting to interviews in the first place, that's a different problem from what this article covers — it's usually the CV or the targeting, not your technical knowledge. jobmarket.pro reads the full advert against your actual work history and prepares the application from that, rather than a generic template, which is where a lot of accountant applications lose out before anyone gets to ask you a question at all.
