It's a numbers game. you have to get your CV on the top of an employer's pile of applications on the day he has a vacancy. Do your homework and make sure you write directly to the employer by name and say why you want to work for that particular company. If writing on spec send a reminder letter a month or so later with an updated CV including everything you have done since your last letter. Your CV has to draw his attention over everyone else's. A lot appear to be written by dead-heads so make sure it is relevent and include your interests and hobbies, especially if your work experience is a bit thin. I would expect an applicaion to include evidence of a genuine interest in a technical hobby or something that included craft, diy, or creative skills. You will be expected to talk about them at interview so don't fill it bull of bull.
I got over 100 applications for a 1st year apprentice post so be prepared to send out 100 applications. If you really want it and are prepared to do the ground work, you will find somewhere.
