How to make most out of IS major in CMU for a Software Engineering career?

The most efficient/best route to a career in software engineering would be a CS degree, but SCS in CMU is very competitive. I guess another other option would be an IS major. I have read on Quora and Reddit that IS is not very interesting to many people and that you will need to work harder if you want to have a career in software engineering. This is also reflected in CMU’s post graduate outcomes. IS majors go into Business Analytics and consulting as well as software engeering. So my question is:

  1. Would graduating with an IS degree disadvantage me in getting a software engineering job? If so, by how much?
  2. What can be done to make the most out of an IS major if what I want to do is software engineering? Is double majoring in CS viable and is it a good option? What about minoring in software engineering?
