J.P. Morgan Software Developer interview questions

Discussion with recruiter, several phone interviews. The interview process is as usual but very inefficient. They don't have any calendar so there were several back and forth to schedule. Also one interview was like 8:30 PM. I was interviewed by 4 engineers (other than recruiters). IMO, all went well. However, one particular interviewer was extremely unprofessional. At the end he asked if I had any questions which I answered "yes" and asked the question. His reply was ~"this is a great question, i guess you'll ask the same question to other interviewers...." I was like WHAT? but I replied while gently laughing (to just ease situation) 'I am not sure if I'm going to ask other interviewers same question'. Well, I may or may not and i believe it's ok to ask same questions to different members of team to get individual perspectives. Don't different interviewers ask same question to interviewees? But point his how and why he predicts/judges that! However, after I challenged his "judgement", he softened it like ".... (next person) will be better person to reply this question". At that point I've decided I will be very critical about this team. However, next person, however, was extremely cool and professional. Also he gave me chance to ask questions before he could ask me and and wanted to re-schedule another meeting for his questions if my questions take whole session. However, after 4th interview they decided not to move forward with me as they're hiring someone else. So hiring someone else was fine but I'm not sure whether that's generic response or not; there is no way to confirm. IMO, I couldn't correctly respond 100% of the questions but I've done fairly well. So I will just take it that they found someone with better skills/knowledge.
