Telephonic was quite better but they were asking very conceptual part of Java from basic to moderate. The f2f technical round, they asked about your project and data flow diagram for the project done. Final year project also asked. Coding question from String, Inheritance. Experience was good. But Got rejection due to lack of strong coding skill. Theory portion will not worthy if you sat for intern. Good hands on practice of coding will only crack the face 2 face technical round.
