My second round was MCQ round. 20 questions were on analog and digital electronics and the next 20 were c++ based. The question was simple like digital circuits are given you need to find boolean expression for that, digital circuit miniaturization, No. of NAND required for XOR and XNOR, basic questions on RC coupled amplifier, Reflection coefficients. In c++ MCQ were also simple like pre-increment and post inc operators, switch statement MCQ, a short program is given and you need to tell its output.
