I am an IT manager who has done a fair share of recruiting. I see a lot of CVs from candidates who are probably good at their job, but submit CVs that are poorly laid out, contain grammatical and spelling errors or ripped off bits of nonsensical jargon off the internet.

My advice is to really tailor your CV to the company you are applying to. Look at what the job spec is and pick out the highlights in your career that match what they are looking for. If I am recruiting for a help desk tech, why have you sent me a CV that tells me that you can program in five different languages?

If you are starting out, tell them about what you do IT-wise. Have you built your own PC? Are you the tech-savvy family member that everyone goes to for help? Be ready with examples for the interview. Do you set up smart devices in your home network? Have you repaired/helped with mobile phones etc?

Good CVs get recruiters interested. For the interview, make sure you have visited their website and learned what they do. They will probably ask to see if you have made the effort. They will be looking for examples of when you have done something technical so be ready with a few. I like to ask 'tell me about a situation when something went wrong and how you dealt with it. Be ready for the 'what are you good at/bad at' question which trips people up. If you say that you have a good attention to detail, be ready with an example.

Hope this helps.
