Step by Step Process and Experience:
(1) Uploaded CV and completed online job application form
(3-4 Days Heard back from recruitment team to say you have been selected for a Video Interview)
(2) Video Interview, very simple, remember to relax you can turn of the screen so you can not see your self and I had interview notes behind the screen to reference, at this stage you must do research on the questions they may ask you, you get 2 attempts per question.
(3-5 Days later they invited me to an assessment center which is the final stage, be patience the next email you receive gives you the location and date of the day but there was around a 4 week period where I heard nothing, I called in to ask, the next couple of days I received that email.
(3) Assessment day, Arrive early and be prepared, have notes about the company and questions they may ask you, I had 20 candidates on the day but remember we are from different areas and not competing against each other, English, maths and ICT tests are not see what level you are working towards as you will doing a NVQ if you get the job, these are really simple and I belive they do not effect the outcome of the day. Practical test, they will give you a run down and demo of what you need to do and you have to repeat it, its really simple just connecting a few wires, stripping some wire etc, remember to wear the goggles, clean up and put tools back after. Interview time, two interviews with patch managers who look after a team of engineers, be friendly and confident, relax they have been in the same position as you (Questions are below) Before all of that you have a presentation by the recruitment manger which tells you about the job, there is some sitting around but there are experienced engineers in the room and it helps to ask the questions. Remember passport, driving licence and proof of address and do research about company.
(2-3 days later email to say you've passed or failed, I passed but they said there are not jobs in the area at the minute but they will be in touch, I believe this is a trend and am holding out for another email, this doesn't mean you don't have a job, just hold fire!)
A good experience all round, when they offer me a position you are required to go to the training center for a week which is up north, for me this is great a whole week away from the misses! Then you spend around 4-6 weeks in your local training center and then are deployed in the filed with a buddy. The whole process is very military, ive done army recruitment before and Open reaches is very much the same with out the 3 mile run.
Hope this helps!
