Worldline interview questions

Got an call from consultancy , she scheduled the technical interview there were total 2 interviews 1 tech + 1 Mang. The Interviewer was a girl , she asked me some very good basic tricky Core JAVA questions , I answered all of them except 1 , In the end she told me that I am very good with Core java , as I don't have much experience with UI she told me that she is okay with it and will talk to her manager to go ahead with your profile. Later on they rejected me saying I don't know anything in Java, She didn't asked me single question on microservies but reviewed that I am not much aware with microservices . These things points why this company is having low ratings. Wasted my time unnecessarily , chased the HR as I was sure that interview result will be positive.
