You're correct that the policies are an important piece of information, but where you're mistaken is thinking there's a chance in hell they will be favorable to you. You'll find this to be universally true among companies of this size. If you have pre-existing IP, there will be a method to document it laid out in the policies. If you develop unrelated IP completely in your spare time and using your own resources while employed there, there may be language in their policies that describe an avenue to lay claim to this IP.
