Afraid I've dug myself into a hole
andr: Over the last 4 years you've gained more than SAP-specific knowledge. You've developed a process, or methodology, for solving problems. This is very important, and smart employers will recognize it.Also, use your spare time to code in one of those languages so you have something to show employers. I would suggest a more advanced language, such as Scala, because Java, C# and Python are all essentially subsets of Scala.For what it's worth, I had pigeonholed myself into PHP/MySQL development and was getting sick of it. So I applied for a summer internship with a financial company and got to work on some much more interesting stuff. Of course, I was still in college, so your mileage may vary, but what I'm trying to say is that if you want to change courses just start applying.
