I'm afraid that question is a bit too open ended to get a good response. We'd have to know a lot more about your current position and the new company to give you anything of value. Also we'd have to know a lot more about your current job responsibilities and those required by the new firm.
Ex. A non-profit might require you to use open source tools while a specific company may require proprietary tools. It all depends on the companies.
