The first round is classic 30 minute HR question. The second round is technical interview. Mostly questions regarding Java concepts and implementations - data types, multithreading etc. One short problem solving question. The third interview was something between technical and HR, mostly discussing my CV and the project I'd work on if hired.

Failed the prelims, planning to apply for next opening in February/ March, getting ready for opportunity this time, at least to get to real interview. You got like a test and problems combined for a limited time, so you try to do as much as possible
