A sound technical round followed by HR & document verification.process is very prompt.Though the selection takes few more days but company checks all the finer details and background.They ask less difficult but useful questions related to check basic electrical working knowledge e.g To reduce the mutual inductance in corresponding phases of electrical TL after certain lengths (generally total length( L)/3) the conductors are transposed from R to Y to B and in which tower this transposition takes place is called transposition tower
