aptitude was simple….work a lot on series…its part of all company’s aptitude…in siemens aptitude questions on blood relations, series, work were asked….To be frank. i’m bad in aptitude…n so u r…better strengthen yourtechnical, C n C++….
C n C++ is a part of parcel of all interviews…


In my interview…it was a 45min grilling…..
I was questions on lex, yacc, parser,a lot of unix, inheritance, constructors n destructors…
But it wasn't the same for my frens.. they wer grilled on inheritance n other things…only I was targeted on unix stuff…208 wrote the aptitude out of which 20 wer short listed…among them only 8 were taken..i was the last one to be interviewed…n picked too…I on top of the world for getting into SIEMENS…
This was the third company to visit our college.. first was TCS which I intentionally left cos I din like it..Next was emphasis…aptitude was dead easy which cud be answerable by an 8th std kido too…but I din get selected..n ten was siemens…So on that account wishing everyone ALL THE VERY BEST.. MEET U IN SIEMENS….
