Unfortunately some people find that a degree can actually make getting some types of jobs more difficult. You may be considered to be overqualified for certain positions and therefore an employer will not take you on for fear you may want to leave as you are not being challenged.
There are graduate positions available in many big companies and they may not be completely dependent on degree subject. However, these can be highly sought after and therefore not easy either.
Some jobs will need more than a degree as well, perhaps a post graduate qualification or work experience too.
So, unfortunately the answer to your questions is that you will not find a job easily with a degree. It will depend on what type of job you want as some will require a degree and others will not. Some will require further qualifications and others work experience. Therefore consider what career you want and then decide whether a degree is the right choice for you. If you already have a degree and are struggling to get a job, consider doing some voluntary work so that you have some work experience to boost your CV.
