It was a walk in interview. It was well organised in general but they were confused about my profile and I was fitting into both the job profiles up for offer on that day. I was interviewed by both the teams and finally the managers of both the team addressed me together and gave me details about the work so i could decide where my interest lies. The HR interview was on the same day, which i found was very trans parent and honest, as was I. He even gave me some pointers about career path. The offer release process was really slow. Took one month to come up with the offer which was a lesser than what was discussed earlier. I am still waiting to hear from them again about the counter offer.
