The best place for jobs information is your Careers Advisor, Mrs Eli Parsons, along with the Careers Wales website. You could also look at online recruitment agencies, local council websites etc, and even shop windows in the high street. Talking to family members can also help if you are looking for a job.
First of all though, I would start with Mrs Parsons and the Careers Wales website. There is a ton of information about all different kinds of jobs, a job matching quiz, how to write a CV, fill in an application form etc all in one place in their 'Getting a Job' section (link below). There is also a link on the 'Getting a Job' page to loads of websites that advertise jobs (link below).
If you need any help at all please contact one of us on the Contacts page.
