UnitedHealth Group Senior Software Developer interview questions

Interview process included two technical rounds and one managerial round. I was called for interview at Unitech cyber park location in Gurgaon. First technical round- basic oops questions Second technical round - advanced questions on oops, .net, c#, design patterns, sql, etc. It went on for more than one hour. Taken by some guy at lead position. Managerial round- Questions related to personality and scenario based approach. Taken by project manager. After clearing all the rounds the Spoc came to me and said that I'm selected and HR will be calling me for final discussion. I can leave for the day. All this process took 8 hrs from morning 10 till evening 6 on saturday. After this I followed up the HR for next 40 days. I dropped 5-6 emails but got only single response at last which stated that business has holded the offers. Again the positions came up on Naukri.com, I applied and immediately HR person called me, I told her the situation and she told that she will call back after discussing with previous HR and will definitely resolve the issue but again no communication afterwards.
