Knowlarity Communications interview questions

3 rounds 2 technical and 1 with the HR , applied from linkedin. questions were from OS , networking and coding. then there was a problem based on real life scenario.

Applied through Naukri and got a call from the recruiter. Had initial discussion and proceeded with the first technical round. The questions was pretty average after which I didn't hear back from the recruiter for any updates. I had to call her and she said I cleared the round and forgot to tell me. (Very odd) I then had another technical round taken by one of their technical heads which was more or less based on System Design. I was pretty confident after the interview and was awaiting their call (which never came). A week goes by and I had to call the recruiter again myself and had to re-introduce myself to her because she seemingly didn't recognize me. She then proceed to tell me that I had cleared the rounds and we than had a discussion about salary and perks. She said she will reach back to me for start initiation process but again THAT CALL NEVER CAME. Very disappointed with the unprofessionalism shown by the recruiter who then never replied to my emails/messages or calls.
