I feel as if we are very similar. I to did not give two shits if I got hired or not. Do not stress things and answered most questions how I thought the FAA would want me to react as a controller. 20 years old. CTI Grad. Now pursuing a degree in Exercise science. Still got green check mark.I'm INTJ most days. Some days I change to INTP. But mostly the former.
I'm very laid back and don't stress over things. For example I almost couldn't care less if I had been accepted in this bid or not. It really isn't worth it. I like people but I'm not very social. I'm considered very intelligent by peers. I had a bachelor's degree in physics before doing CTI. I don't think any of this will help understand anything because I consider this process to be completely inept and purposely fairly arbitrary. I also answered the questions as what I think the FAA would want to hear and not necessarily how I personally would feel.
Hope that helps.
