Recruiter called and said it is very urgent and they have can select within 1 day and release offer next day and scheduled the interview immediately. 1st round was more of project experience and went for 30 minutes. It went well. After which there was no response and I heard from another person the same story where 2 months back also HR called and told the same story like very urgently position has to be filled but left with no response. Only after the interview they decide the budget it seems.
