Environmental Protection Agency Environmental Protection Specialist interview questions

I was contacted for an interview after passing the evaluation process through USA Jobs. I was highly qualified for the job position, but thought it strange they were classifying the position as a Environmental Protection Specialist, which requires no degree. The interview itself consisted of two individuals in person and about four people on the phone. They each had a list of questions....it was weird taking the questions from the phone interviewers. They mostly asked me general questions which could be answered in "yes" or "no" , but I thoroughly elaborated on my responses. The only technical question came from one of the phone interviewers, "How would I go about evaluating a permit application?" I have over 20 years of permitting experience so I know I nailed that respons. There was not one question that I stumbled on and I have not received a rejection letter after 2 months (which is also weird). The only thing that I can guess is that they have some non-degreed candidate earmarked for the position. I am a current federal employee and if I scored higher than their intended candidate they may be waiting for the list to expire because I don't think they can hire below me.
