J.P. Morgan Java Software Developer interview questions

Interview was scheduled by HR and when am at venu no one showed up until 30mins passed and I called hr who not lifted the call later caller another alternate number which was answered and finally 3 people showed up. 1st round held by 3 unprofessional species, had no resume of mine, no pen, no papers it shows how good they want a resource to there team. They started with Java core I tried my best to reach them(they r good ) and later moved to spring boot where the actual torcher started they aimed to prove that I am not fit and should not keep anything in resume until unless I know it 100% not even 99% actually am so interested towards spring boot and used to learn alot on it and am confident on it but there behaviour made to me say I dont know even I know the topics because am afraid do I need to work with this people. And they gave me a suggestion dont keep anything in resume until u know all about it. They could have told me am not fit or not upto mark which is accepted and respectful. But they commented on my current company comparing with his friend who is already working in it and my college. From there afraid do I need to end up working with this mannerless people. After all this nonsense 1 of the 3 questioned me sarcastically how was the interview I said it's GOOD with tears in my eyes that's how they treated. Before this interview I had very good opinion about JPMORGAN it's one of my dream company but now I feel how they have such an unprofessional interview panel who had no manners at all.

First round was scheduled in Bangalore office, which is technical. The interviewer was not at all interested to take up the interview. Just for sake he asked few questions. He was interrupting in between when I was explaining the answers, and was asking irrelevant questions. Simply waste of time.
