Accenture Sr. Software Engineer interview questions

two Technical Interviews, one HR interview, I was selected but got a joining call 6 months later. I joined another company before that.Interview process want very smooth and well organised.

Interview contained 2 rounds. Online test and face to face. I cleared both round. HR(Ritu) told me HR will call you for final discussion. I didn't received any call. I follow up then they told me position is already given to someone. After 2 month i received call, HR told me there is one face to face technical round again. I told ok but she didnot send any confrmation call. I called n mailed her but she didn't pickup my call
