Online Application - This took about an hour and a half to fill out, making sure to provide full and correct GCSE results and other qualifications. Pay extra attention to the motivational questions.
Situational Judgement Test - In my experience, I got invited to this a few hours after submitting my application.
This is a multiple choice test, asking for what you would do in certain circumstances. You will need to meet an undisclosed score to proceed.
Video Interview - Following a successful SJT and short listing, I was invited to do a video interview (this is a new stage, I believe).
In this stage, you are asked 3 questions and given a 30 second window in which to record your answer. You can review and re-record your answers AS MANY TIMES as you like! Questions I was asked included "How would your friends describe you?", "Why did you choose the National Grid?"
Assessment Centre - After further short listing, I was lucky enough to be invited to the assessment centre which is the last stage of the process.
You are invited to their training academy in Eakring the afternoon before the assessment day, where you get the chance to meet the other candidates and have an evening meal together, along with the staff who will be assessing you the next day. They make a point in telling you that you're not being assessed at dinner, and to relax and enjoy your evening!
The assessment day starts bright and early, with a range of tasks and tests arranged throughout the day. You will do a colour blind test, manual dexterity test (Taking apart a gas regulator/putting it back together), a basic mechanics test and an interview. All the tasks are really straight forward and well explained, so don't be too nervous. The interview itself was quite intense from my experience, they ask you a lot of questions about your motivations, achievements, situational awareness and your knowledge about who the National Grid are.
