I had a campus interview, there was one written round, 2 Technical interviews and one (only namesake) HR round. Written round consisted of aptitude, C C++ multiple choice questions (and some other topics which I don remember but it was less difficult), it also consisted of 2 coding questions and written round was conducted by cocubes.com Among 120-160 people appeared for written round only 13 got shortlisted to next round. In second round I was asked on my projects done during my internship, it went on for about 70-80 minutes and in that almost 50 minutes there was discussion only on the projects and there was only one question on Networks, but my friends who didn't had much projects were asked questions on many topics such as OS, Networks, Data Mining, DBMS. Among 13 candidates they shortlisted 8 into next round. In this round I was asked about advanced data structures and Algorithmic concepts, they were checking my depth in fundamental concepts(Algo, Data structures). Mainly they were asking on TRIE data structure. At last there was two puzzles. Finally HR came with goodies and gave the good news :) :)
