You need to prepare for job applications as you would for an exam, maybe even more so.
I only got a bachelors and had no relevant experience when I was looking for a job, but I ended up getting more offers than my friends who had both of those things. Its because I made the most of what I had. Too many people with good qualifications think that a job will just fall in their lap, but you have to work at it.
I would advise going to your careers centre and getting help with cvs,applications and interview techniques; they'll teach you how to best present yourself. If thats not an option ask somebody more successful than you for help.
To people in their final year, I recommend sacrificing a bit of time that you spend working on your degree and work on your job applications instead. After all that is the main goal for many of us at Uni.
