Help hiring a CTO [I will not promote]

Hey guys, I'm currently in the process of hiring my first CTO for a startup. I have a good all around skillset; I can do sales, marketing, designing for websites and apps and I can build financial models and interpret them, but I'm at zero for is technical skills (coding). I want to understand every part of my startup to be able to address and solve any issues in any aspect of it with whichever team mate is looking over that side of the business. My 2 questions are: 1. What should I be learning and where do I start to be able to understand technical challenges and technical knowledge so I understand what my CTO is saying? 2. What should I look for in a CTO? I'm a new grad and so is my prospective CTO, so our resume's aren't anything crazy. I met him after I put a job post out in my university saying that I was looking for a CTO. I will not promote
