Compunet interview questions

Applied for the position July 16. Compunet recruiter contacted me two months later on September 16 to schedule a video call with the hiring manager. During the call, the conversation was stunted and offered up were vague questions like, "Can you do this job?" My resume states 18 years of engineering, why is my ability to perform this job even a question? I received a terse "Unfortunately..." email. I asked for interview feedback, none was provided.
