this round is somewhat difficult,where they q's from digital &analog electronics,microprocessor &regarding project around 1 hr or more.so prepare accordingly.
q's like realize nand,nor,and gate using cmos only &also do d same using BJT(indirectly abt TTL,DTL,ECL),16:1 mux using 2:1 &its char eqn,encoder & decoder,flipflop convn &race condn,k-map,counter,plot the output(based on d concept of reset & preset),metastability,io curve for bjt in ce,cb mode,zener diode ,op-amp,8085 interrupts,interrupt routine,WAP to rotate etc.so be enough confident in digital.
all d best

as usual,normal genuine q's ,jst formality.noone got eliminated in this round. wish u all d best.

do's:- be confident with a smilling face.if u dont know d ans,then try to speak something related that(dont bluff),because they rejected abt 20 stud taking only 10-15 min int due to this.
never argue with d int ,instead try to modify ur ans in diff manner.

it's an offcampus drive held at wipro tech,bbsr. around 200 students selected for tech int.out of which 22 got selected
