I am on the verge of completing my degree/qualifications and switched job recently, from the public sector to the corporate sector. I was in a somewhat similar situation, because my degree doesn't guarantee me anything in my previous job. Morever, it is totally irrelevant, which is why i took the decision to leave.
1 month into my new job, i have already discovered how different and how tough the working environment is. And now, i am like so many other here, stuck in a job, just working because of the bread.
