Ola Senior Java Developer interview questions

I was invited at Ola Bangalore Office for the interview. I had 3 technical rounds and discussions. After that they asked me to leave and told that I'll be informed about the results next day. I got a call from my contact person named 'shwetank', he informed me that I have a positive feedback and He did all the salary discussion also. He said he will confirm everything after the debrief. I did not received any updates for 2 weeks. he did not reply to my messages or calls. Then one day he messaged me and told that position is put on hold now. I mean seriously..?? after all the process and salary discussion, now this . ? what kind of behaviour this is? a pathetic one I guess
