Its been 20ish years since I applied for a cashiers job but besides basic interview questions, the questions I remember that pertained to being a cashier were pretty simple, they just wanted to make sure you could do simple math and count back money. One place on the application had said a customers bill come out to X and they paid with a $20 bill, what would you give them for change, draw out the bills and coins. Another place in the interview did basically the same thing but wanted you to figure it out in your head and tell them the exact ammount of change that you would give, exp their bill was 15.57, how much change would they receive and you would answer four dollars and 43 cents. A different company had you me count back change, so a fake sale the bill comes out to 62.23, and they pay with $100, you count back the money to them in the denominations 20, 30, 35, 36, 37, and 77 cents makes 100. Im sure these basic skills are somewhat still necessary, but these days at least in the store I run, 95%+ of our business is credit card, "Your total is X" then they swipe your card and the computer does the rest. They may ask what computer/point of sale exp you have. In the interview, but not directly asked they are probably looking to see if you can communicate clearly and speak to people. Depending on the industry you're looking into the cashier mightbe the only person you speak with through out your entire trip to the store so you're esentialy the face of the company for that visit. There are lots of of protocols to prevent internal theft these days, but being a cashier does take some level of trust, you're handling the stores money. If you don't have any experience handling money or being a cashier they may want to start you in a lower position first make sure you're dependable and trustworthy. This is at least 20 years ago too, my friend worked at a grocery store that had a bulk food section, and it had an honor jar/slot, if you wanted to try something a piece of something before you decided to buy it in bulk you would put a few pennies a nickle or a dime in the coin slot, what ever you felt was fair and you could sample anything but it wasn't monitored, you would never see anyone putting bills in it, the Front End Manager had my friend go empty the coin collector and a $20 bill fell into the bag. So he walked the bag of money up to the manager and said this is kinda weird someone put a $20 in the coin collector. It was a test to see if he was honest and trustworthy before he got promoted to assistant front end manager, and would be counting down the cashiers drawers at the end of the night and dealing with some larger ammounts of money. A similar test was given to me when I was 18(i think min wage was 5.05 when I was 18) The owner started having me come in half an hour early and run the previous days money to the bank and deposit it, after about a week I got to the bank fille out the deposit slip for what his piece of paper said and counted out the money, there was an extra $20 in the bank envelope, so the bank let me call him on their phone and I told him theres an extra $20 in here, do you want me to deposit it or bring it back to you. He had me deposit it. Turns out it was just a test to see if I was trustworthy and I got some more responsibilities and a key to the store. Some interviews to get a promotion are sometimes strait up interviews, and some "interviews" are just seeing you day to day and how you handle yourself.
