A sample answer to question 1

Why do you want to be a Mobile Phone Sales Advisor, and what does the job involve day to day?

I enjoy technology and I like helping people choose something they will use every day, so this role combines both. A normal day would involve greeting customers, finding out how they use their phone, such as photography, gaming or work, and recommending a handset and plan to match. I would explain the contract terms clearly, process upgrades or new connections, set up devices, and transfer data. I would also offer accessories, insurance and trade-in options where they genuinely help. Alongside selling, I would keep displays tidy, make sure demo handsets are charged and secure, and keep up with new launches and network offers, which change often. I would work to sales and customer satisfaction targets, and follow regulations around credit checks and customer data. What attracts me is the pace and the chance to build repeat custom, because people return when they trust the advice they were given.

Common mistake to avoid: Saying you just like phones; Ignoring regulation and customer data
