I applied online. The process took 4 weeks. I interviewed at SSE (Thatcham, England) in Aug 2017
Interview
There was an online intelligence test consisting of mainly maths and spatial awareness based questions. For example there was different sized plungers connected with a tube and you had to work out the amount the other plunger would rise/fall by.
The telephone interview asked basic questions like why you'd like to work for SSE, your experience, qualifications etc.
The face to face interview had 3 parts, a manual dexterity test where you are given PPE and have to bend a wire into the shape they ask, then a role play where you are an engineer and the interviewer is a customer, and finally a colour blind test. I'm colour blind myself, and got the job, so it's not the end of the world if you don't pass - it's just so they can investigate further.
They also do a background check, driving competency test if you get the job, and have a no tolerance to drugs with random spot checks across the company.
