FHLB Cincinnati interview questions

I found the job listing on their website. I comfortability meet all the qualifications and applied on their website and was called shortly after that for a interview. I meet with a AVP and an Architect. They advanced me to the next round. I went through their coding exercise with a half dozen people, then meet with a AVP and Sr. Engineer. This phase turned into a mentoring session. Received positive feedback from AVP at end. Then I meet with another half dozen individuals. I initially received generic email a week later with no feedback. Requested helpful feedback and instead received offensive comments from AVP. Ended up being a very personal waste of time. I would describe the finial interview process as unwelcoming, perhaps even discriminatory.
