Fidelity Investments Principal Software Engineer/Developer interview questions

my profile was submitted through a resourcing firm, I got an invitation for the managerial round. This round of interview went well then recruiter scheduled a technical round with panel. I am very upset the way this interview was conducted. 2 out of 3 interviewer were rude and unprofessional. At the the start a director level guy gave me a introduction and ask other 2 folks to give their introduction and then I gave my introduction. After this he told one of the guy to start interview, that guys asked me only one question - "Do you have Java 8 experience" I answered I don't have Java 8 experience but I have good experience in java 6 and 7 then this guy told me that I am done from my side, then that senior guy interuppted here and asked him to ask some questions on aws and other tech stuffs. Then this guy asked some basic open ended aws question for example - how geo targeting works in aws, how we can implement IAM policies, then third guys asked me question about the S3 and its access related questions and he was rude as well. I got a feedback from resourcing firm that I dont have good Java and AWS experience and that's the reason fidelity team rejected me. I didn't mention Java 8 in my resume so why they shortlisted my resume for this position and as far as AWS knowledge I have more knowledge than these two interviewers.
