A sample answer to question 1

What does a typical shift as a customer service assistant involve?

I would expect to start by checking in with the supervisor, finding out the day's priorities and making sure my area is tidy and stocked. Through the shift I would greet customers, answer questions, direct them to products, process sales, returns and exchanges at the till or service desk, and answer phone or online enquiries. I would keep the shop floor looking good by tidying displays and replenishing shelves, and check prices and signage are correct. I would deal with problems such as missing items or faulty goods, calling a supervisor when something is beyond my authority. There are also tasks like click and collect orders, gift cards and counting cash at the end of a shift. Some parts are busy and some quieter, so I would use quiet times to learn products and complete tasks. I like that it is varied and that you can see the difference you make to people's day.

Common mistake to avoid: Saying it is just standing at a till; ignoring the housekeeping duties
