Java Senior Interview Questions

6,025 java senior interview questions shared by candidates

I attended the face-to-face interview in Gurugram, Sector 74A. In the first round, they asked me to implement a stack on a paper sheet. In the second round, they asked me to go through some code and explain it. The same interview was then conducted by another group of people. In the last round, they asked detailed questions about my last project, the internal workings of HashMap, the N+1 problem in Hibernate, threading, and basic Spring Boot. After the final round, I received feedback stating that I was rejected because my communication skills were weak, even though I conducted all the interviews in English. I feel they didn't consider my technical skills. In the last round, there were four candidates, and they rejected all of us. The entire interview process took the whole day. I think HR should first ask if you are very fluent in communication skills before allowing you to proceed with the interview. It was a waste of time.
