Then the major part is networking, if you gone through by successfully explains your coding then you will be completely checked with networking which is really tough, like they asked me that to tell port no of telnet ,how can someone remember that in that time, and told to draw FTP ,what can i draw for that. The most worst thing is that only in my panel they asked these kinds of questions , not in others so in other panel they only asked for self intro and code that's all. so it is mostly on luck on which panel you go, and there is no shortlisting for written test , i was called suddenly once im done with my written test for one to one interview.
