Telephone interview which was brief, general question why do you want to work here what experience do you have? If successful then you are invited to the assesment center were you will sit a face to face interview with another engineer and someone who writes down what you say. The questions are based on your tests online that you are sent before you go so for the behavioural tests keep a sharp mind and be honest how you answer. Then you are called in to do a mechanical reasoning exams and colour deficiency test. If you are not successful on the colour deficiency there are alternatives ways of checking. Then you are informed after 7 days.

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.
