J.P. Morgan Application Developer interview questions

HI , I have been interviewed by JP Morgan 2 weeks back. First round was telephonic and cleared it.Second round was conducted F2F after one week.Cleared and HR scheduled the VP telephonic round of interview after one day.Surprisingly didn't received the call.So called HR, she apologize and said i will be informed if any further round needs to be done.I thought i got rejected before giving VP round of interview.Again surprised as got a call from another HR to give the HireVue coding test first.Then managerial round and then VP round and lastly HR round.By this time already felt screwed up so lost interest in giving further interviews and informed the same to HR .So finally she got irritated and sent an email that i will not be considered again. I thanked her for not considering me again as i will save my days in future from this company.(It was my dream company but shattered badly by the hiring process). My advice to candidates to ask clearly from the HR in email the interview process and then proceed further.After all Its your time and effort you are investing, so invest wisely.
