Selec Embedded Hardware/Software Trainee interview questions

I registered for Selec control pvt ltd from my college. It was started with an aptitude test completely technical (don't expect quants). Total 40 questions were asked and out of that 12 were based on C & C++ programming and rest were mixed ( DSD + ECAD + Circuit networks + BEC). Simply based on basics. Second round was Group discussion in which total 10 people were in a group. Third round was held in the company itself . We had been told that there will be technical interview and then HR but the scenario was different . First their was my HR interview and then a logical test (big surprise for me). But logical test was quiet easy. After got selected in those rounds it was my technical round which was supposed to be the final round. They asked me questions related to my project , my interest in hardware field and also conformation to work as much as possible in selec. After such a long drive process which was of 1 month i was selected in selec contro; pvt ltd.
