It looks like the OP wants to know what the real work environment is like. As many people mentioned before, it depends on the company. If you work for some large corporation with plenty of office space, it is likely that you will get an office by yourself (but it also depends on the job).
I have a dual degree in Accounting and Finance. My first job was an entry-level financial analyst in a large bank. Although the job title sounds cool, but really it was nothing more than data-entry job. The software does most of the analysis with the real analysts high up in the hierarchy interpreting the result. I got my own small cubicle, my own computer, and a desk that was always cluttered with stacks of paper. I got about 1 foot high fresh stack of report paper every morning. Office politics did exist, especially when things went wrong and some people started shifting blames around. However, not everybody is like that. Many people I knew there were really nice and highly responsible people.
My second job was in a manufacturing company in a suburb. My former manager from my first job pulled me into the company. My computer knowledge added with my number-crunching skills made me the production assistant. The job was basically keeping track of the production while generating various forecasts for the next production needs. I got a shared office with the production manager. There was hardly any office politics, and the manager was old enough to be my dad. The office wasn't as polished as the one in the bank, but the salary was definitely better. I was there for quite a bit. I was their finance / accounting manager before I resigned to start my own business last year. As the finance / accounting manager, I got my own private office, with accountants working in their cubicles outside my office. We got the whole floor for ourselves.
Now I am back to a small office in my own business.
