There are several ways in which you can start searching for a job that may be suited to your skill set, qualifications and commitment.
You may decide to go to the job centre and either speak to an advisor or many now have online computer systems you can use to find jobs that match your skill / experience level. This can be particularly handy if you are not exactly sure as to what you want to do or the opportunities open to you.
The other place you may want to look is on online jobs boards. There are quick and easy to use and allow you to search through hundreds of jobs at a time. You can usually filter the jobs that come up by job type, location or salary and some allow you to refine this more by selecting qualifications you have.
A CV is a very important tool when applying for jobs. This document can mean the difference between asked in for an interview and turned away at the first stage. It is vital that your CV is up to date with all of your education / qualifications as well as any working experience you may have. If you have an up to date CV to hand you can quickly apply for jobs even if the deadline for applications is closing soon. You should always tweak your cover letter for each company that you are sending the CV to as the covering letter should be quite specific to the job you are applying for whereas your CV is likely to be more generic.
