A sample answer to question 1

Why do you want to be a smart meter engineer, and what does a typical day involve?

I like practical work, being out and about, and dealing with people rather than sitting at a desk. A typical day involves a set route of appointments, usually six to ten homes, where I check the customer's ID, explain what I'm doing, safely isolate and replace the electricity or gas meter, install the in-home display and comms hub, and make sure the meter connects and communicates. Then I run safety checks, complete the paperwork on a handheld device and leave the customer confident they can use the display. I also like that it supports the move to net zero, helping households see their energy use. I know it involves lots of driving, lone working and varied weather, and I'm happy with that. I also want a career where I can gain qualifications and progress.

Common mistake to avoid: Focusing only on pay; Unaware of the safety side
