Most Common Cashier Interview Questions

1. Which POS systems and till software have you used?

Why they ask: To confirm technical competency.

How to approach: Clearly list the systems and software you have used.

Sample answer outline: At [the company you worked for] I used [the till software/POS system]; I am confident with barcode scanning, refunds, different payment types and end-of-day reports. I usually get up to speed on a new till system within a few shifts because the logic is similar in most. I have also actively handled contactless payments, gift cards and promotional offers.

2. What do you do when you find a discrepancy in the till?

Why they ask: Measures honesty and knowledge of procedure.

How to approach: Explain reporting the shortfall to your supervisor straight away and documenting it.

Sample answer outline: I never try to cover or delay a till discrepancy on my own; the moment I spot it I report it to my shift supervisor. Together we check the day’s transactions and try to find the source of the difference (wrong change, a refund error, a system entry). Whatever the outcome, I want it recorded in writing; transparency is a precondition of working on a till for me.

3. How do you manage a long queue at busy times?

Why they ask: Assesses the balance between speed and customer satisfaction.

How to approach: Explain fast processing, polite communication and asking for help.

Sample answer outline: At busy times my priority is to speed up without making mistakes; I use my practised handling to move items through faster and cut out unnecessary chat, but I never drop the courtesy. If the queue passes a certain point I let my supervisor know and ask for another till to open. Brief eye contact and a "I’ll be right with you" message noticeably eases the tension for waiting customers.

4. How do you detect counterfeit banknotes?

Why they ask: Measures security awareness and attention to detail.

How to approach: Explain your method of checking security features (light, pen, touch).

Sample answer outline: Especially on higher denominations I hold the note up to the light to check the watermark and security thread; I verify the raised print by touch and the colour-shifting features by tilting it. If there is a counterfeit-detection pen or device at the till, I always use it. If I come across a suspect note I explain the situation politely without accusing the customer, and call my supervisor as procedure requires.

5. How do you deal with an unhappy customer at the till?

Why they ask: Shows your communication and composure.

How to approach: Emphasise a calm, empathetic and solution-focused approach; call a manager if needed.

Sample answer outline: First I listen without interrupting; often people just want to feel understood. If the problem is within my authority to resolve (a price check, a transaction correction) I do it straight away; if not, I say "let me get a colleague who can sort this out for you" and call my supervisor. I never get into an argument in the middle of the queue; a calm tone of voice settles both the customer and the queue.

6. How do you manage returns and exchanges?

Why they ask: Assesses your knowledge of procedure.

How to approach: Explain an approach that follows company policy and keeps the customer informed.

Sample answer outline: I always process a return according to the company’s written policy: I check the receipt/proof of purchase, the condition of the item and any time limits. If the conditions are not met I explain the reason to the customer clearly and courteously and offer an alternative if there is one (an exchange, a gift voucher). I do not decide on exception requests beyond my authority myself; I refer them to my supervisor, so both the customer and the business are protected.

7. How do you cash up the till at the end of the day?

Why they ask: Measures counting discipline and sense of responsibility; they want to see how orderly the person the till is entrusted to will be.

How to approach: Explain the counting, reporting and handover steps in order; stress that you never rush it.

Sample answer outline: At cash-up I first count the cash denomination by denomination, then reconcile the card and gift-card totals against the system report. If there is a difference I look for its source before handing over; if I cannot find it I report it in writing. I never rush the count; making sure every figure reconciles when I hand the till over is my responsibility.

8. How do you take over and hand over the till at shift change?

Why they ask: Assesses handover discipline and a sense of accountability.

How to approach: Explain your habit of counting on take-over/hand-over and confirming it in writing.

Sample answer outline: When I take over a till I always count the opening float together with the previous colleague; I cannot accept responsibility for a till I have taken over without counting. When I hand over I count in the same way, together, and record the figure on the handover form or in the system. This mutual discipline protects both me and my colleague from any later dispute over a shortfall.

9. What do you do if the shelf price and the price read at the till are different?

Why they ask: Measures knowledge of procedure and your approach to the customer in a common dispute scenario.

How to approach: Explain the flow: verify → resolve in the customer’s favour/per policy → report the label error.

Sample answer outline: First I apologise to the customer and get the price verified; if needed I ask a colleague on the shop floor to check the label. I apply whatever the company policy dictates and explain the process to the customer without keeping them waiting. Afterwards I always report the label error to the relevant team so the same problem does not happen again with another customer.

10. What do you do if a customer leaves without realising you have given them too much change?

Why they ask: Tests your honesty reflex through a real scenario.

How to approach: Explain correcting it without hesitation and recording it; show that honesty is not negotiable.

Sample answer outline: The moment I notice, I call out to the customer, or if I cannot catch them I report it to my supervisor immediately; the difference is held at the till and recorded. I show the same care with short change; the customer’s entitlement and the till’s are the same to me. In cashiering, once trust is broken it is hard to win back, so I take even the smallest amount seriously.

11. What do you do if you notice a colleague making an improper transaction at the till?

Why they ask: Measures ethical standing and the will to protect the company’s interests; a difficult but distinguishing question.

How to approach: Emphasise procedure over gossip: confirm what you saw, report it to your supervisor, and leave the process to the company.

Sample answer outline: First I try to be sure of what I saw; there could be a misunderstanding. Once I am sure, rather than discussing it with other colleagues I take it directly to my supervisor, because this is not gossip, it is the security of the business. In situations like this I believe staying silent means becoming complicit in the wrongdoing.

12. Are you suited to standing, fast-paced work and to weekend and shift patterns?

Why they ask: Assesses fit with the physical realities of the job and the risk of absenteeism.

How to approach: State your availability clearly; back it up with previous fast-paced experience.

Sample answer outline: Yes; through [your previous job/experience] I got used to standing, high-tempo work, so this pattern is no surprise to me. I can fit in with weekend and shift planning; advance notice of shift changes is enough. I see regular, reliable attendance as a basic requirement of the job.

13. What method do you follow to avoid mistakes with promotions and discounts?

Why they ask: Measures attention to detail and the habit of keeping information current; promotion errors cause both till shortfalls and customer complaints.

How to approach: Explain your habit of following promotion announcements and asking when you are unsure.

Sample answer outline: At the start of a shift I always look over the current promotions list; I would not sit at a till without knowing which products carry which conditions. Even if the system applies it automatically, I check that it is reflected correctly on the receipt. When I am unsure about a promotion condition I ask my supervisor rather than guessing; processing on the wrong information hurts both the customer and the till.

14. Why have you applied for our cashier role, and what makes you good at this job?

Why they ask: To understand your motivation and self-awareness; it aims to filter out candidates who see the job as temporary.

How to approach: Match your genuine strengths to the real requirements of the job, such as attention, speed and people skills.

Sample answer outline: I am someone who likes careful, orderly work; I think those qualities pay off at a till, where two sensitive things — money and customers — meet. In a busy, well-run place like [the business you applied to] the pace does not tire me; if anything the day goes faster. In the long run I would like to take on a role with growing responsibility in the store thanks to my reliability.

How to Answer — The STAR Method

Use the STAR structure to answer behavioural questions with a strong story:

  • Situation: What was the context?
  • Task: What was your responsibility?
  • Action: What did you do?
  • Result: What outcome/impact followed? (with numbers if possible)

What to Highlight in the Interview

  • Always state your till discrepancy rate — "under 0.1% discrepancy" is the strongest proof of your reliability.
  • Give the number of customers/transactions you handle a day; it shows your speed and stamina.
  • Say that you cover busy hours, weekend and bank-holiday shifts — employers value flexibility.
  • Name the systems you use clearly (EPOS, card terminals, self-checkout).
  • Make one thing stand out: if you trained new staff or became a till supervisor, highlight it.

What to Avoid

  • Just saying "worked as a cashier" without numerical results like discrepancy rate or customer count.
  • Filling the CV with fancy academic sentences — employers want plain, clear wording.
  • Not stating your shift flexibility and weekend availability.
  • Sending a CV with missing contact details.

Frequently Asked Questions

How should I prepare for an interview?

Study likely questions in advance, prepare a concrete example from your own experience for each (using STAR) and rehearse out loud.

How much should I talk in my answers?

Ideally 60–90 seconds per question. Too short seems disengaged; too long seems unfocused.

What if I get a question I do not know?

Be honest; say you do not know, but add how you would learn it or a similar experience. Making things up is the biggest mistake.
