When working in a job role you may decide that you want to move on to something new. It may be that you enjoy your job role but not for the company that you are currently working for or that you simply do not like the career path you are going down. Looking for new job opportunities can be tedious and it may take a long time to find a position you are interested in, especially if it is quite specific.
If you register with an agency or add yourself to a job site you may find that you are offered more jobs to apply for than if you try and search the internet yourself. This is because some companies will only hire staff through an agency and will not advertise the job privately.
Often job searching is a bit of a numbers game and the more jobs you apply for the more likely you are to be accepted for one. Make sure that your CV is up to date with your current job on their and that all your contact details are correct.
