2 rounds of interview. 1st round was mainly on java 8, postgres and other related technologies (this is not exactly an interview/discussion it was the viva, and interviewer seems not to be enough experience to take i/w of 5yrs experience, ill-mannered -- used my resume for clearing the board). 2nd round was more on discussion on akka and reactive programming. I haven't received my feedback till now, even though if I get the offer i won't work with such ill-mannered colleagues.
