Interview process took almost more than 4 weeks. I got a call from recruiter and 2 rounds done over phone and schedule third round for technical interview. After that round received feedback as positive and had salary discussion. I was waiting for another call to have final discussion which never happened . I was following up with recruiter and came to know that they are offering way less salary than they committed. It was so less that no one could have gone for that offer so like saying no in indirect way. I'm really not sure if that position was already filled and they wanted to show that they are following just process of hiring of candidates.
