Total 6 rounds including assignments and panel like interviews all in a single day. After this there was an HR round. One tip I'd give is plan your time wisely if you have all your interviews on-site on a single day.

The interview process had 3 rounds. The last round was HR round and the rest were technical. In the technical round questions were asked on c++ & digital electronics. Topics like polymorphism, copy constructor, inheritance were asked.
