I have called at Persistence for embedded systems interview at Pune through one of the consultancy, the process took whole day, followed by three technical interviews, at the end they ask me to fill the HR personal information form and completed with my HR round. The HR person told me that after some internal approvals, they will contact me within two to three working days but I did not get any call from them. After 15-20 days they called me again saying that I need to face one more technical round. at the same day they conducted it. I have cleared that round next day HR ask me to fill HR form again, I have filled it again and submitted, Its more than 20 days but I dib not get any response from them yet.
