I can't get a job

1.

You need to up your skills whether you like it or not, but also, I think you need to be a bit more targetted. What type of computing job do you want? There are lots but none are generic. Do you want to be a webby developer (Java / C# / Javascript) or do you want to do systems (C++) or defence or government contracts etc etc. You need to do your research and then whilst you are not working, why not work on a project? You must have come across some ideas of things that could be solved by coding? You could go to hackerthons and generally just get involved. Also, make sure that any work you do make is published on your website linked to from your CV.

I've already mentioned it but be really targeted. You are much more likely to get a job if you offer the skills required for the roll rather than just a generic "this is me" application. Make sure as many of the keywords from the application are in your CV and tailor your CV to each application. This is especially true if you apply for jobs through an agent.

Are you prepared to move away from where you are living now? Broadening your search may help. I know you want to work at home, but honestly, at the start of your career and given the demotivation you have shown in this post, I can't see how this of benefit to you or the company that employs you. Put remote working down to a future aim rather than now and just do whatever is required to secure that first vital role.
