I think you start downloading SharePoiint 2010 or 2013 whichever is easier for you. On Windows 7 you need the 64 bit version OS to install SharePoint 2010. When you install the software (evaluation edition will do) you will have the administration site, tool to configure and a sharepoint specific command window where you can use Power Shell, a great tool that you should learn to work with SharePoint. Of course you can also work with the administration site using graphic userinterface.

Here's the best tip you'll ever get about starting a new job... Forget everything you learned in college. You are in the real world now. I think you will find that the work environment will shock you at first. DON'T cause trouble - you are there to learn everything you didn't learn in college, which is, well, everything. So, keep in mind, when you see something that feels wrong, don't point out that it's wrong, try to figure out why it's right in the real world, and what were the lies they told you in college to make it sound right in the classroom.

I like the one with the bugs :laugh:
