For people who are desperate, I have a little personal advice from my own experience.
I think apart from applying for graduate scheme, the other way to go is to upload your CV to online cv libraries, so recruitment agency can search and find jobs for you.
It is very easy and efficient, usually when they approach you, they will have a job in mind that they think you will be suitable for, so let those recruiters help you to find job and have different interview which may land you a job or practice for the real thing ( your idea job interviews/ ACs)
If you are doing an engineering degree, you have a very wide career path and recruiters from diff sectors will want you to work for them as well.
I landed my first job with GRB and i have been appraoched by different recruiters as well, so start uploading you cv and let them bring you the good newsss !!!
