I need more information to give proper help... namely what jobs are you applying for?
What worked for me was this:
After my 2nd year of university I did not want to go back, so I applied for many many many full-time jobs to try and give me some work that I could do instead of university.. I got no where. Eventually I decided to go back to university, but with the specific aim to get a job, not to focus on doing the best I could do in my degree.. (very jelous of people where these are the same thing).
I looked at the jobs that I wanted to do, and that I thought I could do well.. picked about 20-30 positions, and made a large list of all of the personal skills and experiances that they wanted. Ignoring all the overlaping ones, this made a pretty large list.
I then set out to simply make sure I could match or exceed every one of these requirements..
I was lucky, I had a year of univesrity to do this - but its the advice I would give to people now, as ive seen it work for more people then myself..
Job hunting was pretty simple by the time I finished university - I was ticking off every single box these jobs wanted, with a set of skills dirrectly relating to what they required.
-- So that would be my advice.. what jobs are you applying for? When reading their job list, can you match and exceed every one of their criteria WITH real-world exsamples not just university modules/work.
If you can do that, then I cannot believe its anything but a matter of time until you get a job in the type you like.
- My other advice would be to be incredibly pro-active.. a few of my friends are currently working in companies that they just went up and approached.. my best friend knew the area he wanted to work in, and he just phoned up, offered to work for a week or so for free for experiance.. the first one who agreed.. he went along, worked hard, at the end of the week - walked in to his boss, and said give me a job.. and they did.
So dont underestimate the market for jobs that are not advertised.. companies may be willing to take on a good young individual, even if they do not have such a need for it that they would be seeking/advertising. A lot of jobs come about without any advertisment..
