A sample answer to question 1

What does an IT technician do day to day, and why do you want this role?

An IT technician is the person who keeps the physical side of technology working. On a normal day I'd expect to repair and replace faulty laptops, desktops and peripherals, set up new equipment, image and deploy devices, support printers and AV equipment, and respond to tickets from staff who need help on site. I'd also check cabling and network points, manage the asset register and keep stock of spares. I enjoy practical problem solving and seeing a fix make an immediate difference, which is why I'm drawn to this role rather than something purely desk-based. It also gives me a strong foundation across hardware, networking and user support. I like working with people, so being visible and approachable around the building suits me well.

Common mistake to avoid: Saying you just like fixing computers; Ignoring the customer-facing side
