After entering initial details, I was sent a link to an online application form & test. There were some (very easy, in my opinion) tests regarding numeracy & literacy, plus one of those multiple choice personality profile tests. After completing this I was emailed again & offered a telephone interview a few weeks later. This was quite easy - general competency based questions were asked, similar to some of the responsibilities of of the role. Some research of the company would be beneficial for this part as they do ask questions about what you know of British Gas/Centrica. Immediately after the phone interview - on the same call - I was told that I was successful and if I wanted to, could continue to the assessment centre which would involve some group exercises, an interview & a mechanical reasoning test. The assessment centre date was given to me well in advance so I had time to arrange a day off from my current job to get there (it was just over an hour away from me in Thatcham). The assessment day turned out to be a very long process with a lot of waiting around. Firstly you sit through a very informative presentation about the role, the company, pay, hours, etc. Then you have the interview, mechanical test & group exercise, not necessarily in that order. You are given 10mins in a room to prepare for your interview with a few questions on a piece of paper. The interview was held by two managers & the questions are based answers given in the personality test. Some of the questions were quite difficult to answer. If you have ever done a competency interview though you will be ok. Make sure to note some examples of tasks you have completed, difficult times or giving good customer service. Wear a suit or similar to the assessment day. They don't give you much idea about the dress code but we all had a suit & tie on. The mechanical reasoning test was quite straight forward. I'd recommend doing online practice tests to get an idea of what sort of questions you'll get. We were given 20minutes to complete it which was actually too long for me. The group exercise consists of some tasks for a customer, within a time limit. It's basically to assess both your communication skills and ability to ascertain customer requirements and not promise anything you can't deliver. The tasks initially seem easy until you ask more questions about what is required. It's clear they are looking for candidates who are good with people, can communicate effectively, ask questions & have empathy. Demonstrate these skills and you will likely be offered a role. Overall a good experience and a very professional, well thought out process to get the best candidates.

First had a telephone interview - What appeals to me with a role as a smart energy expert? Customer questions etc Assessment day: About 10 of us on the day, all going different for different areas in general. The group gets split in half, half do an interview, and half do a practical task. The practical task is wiring a board. This is easy since the whole instructions are laid out on paper. You just need to read it before you go. Get about 15 minutes to do so which is plenty of time. Interview for me was facing 3 people, interviewer, note taker, and a line manager. I was told I kept going off point and began talking about something else. Talk too little, talk too much, you never know what the specific interviewer really wants. Presentation at the end, which was just a discussion on how to save money for a customer. This was just a group talk while you are being observed. Dont talk too much as you need to be seen as working well in a team, not as an individual.
