Energy Saving Trust interview questions

During the interview you will have to do an Excel test which requires you to know a formula for percentages. Then you move on to the actual interview I found the questions they asked difficult, I have had a lot of interviews and had never been asked any of these questions before.

It was an easy process from start to finish. I had one, in-person interview that lasted about 30 minutes. They asked all the typical interview questions (why do you want to work here, organisational skills, customer service) and I was informed of the outcome within a few days over the phone.
