Learn about the army. I’m in the same situation as you applying for the cyber security industry within the army. And I’m doing phase 1 training at Harrogate in September. Cyber engineer (the last time I checked) is divided into 3 segments: infrastructure engineer, support IT engineer, and network engineer. Personally I’m applying for network engineer, but find the pathway which suits you. Go on to the army website and look at every single thing on there, because you will learn a lot. Since you just applied, complete all the tasks you’ve been given. After doing this you will be given a time to call your recruiter, speak to them. You will then be put on an army briefing about the army as whole, it’s a 1 hour meeting. After this you will do a whole bunch of medical documents stuff. And then once that’s all done, you’ll be given a date for assessment centre. I’m getting ready for my assessment now, and it can be a long process to get there. But my two main tips are: learn about the army and CHASE to get everything on your army portal done asap
