1) basically they select from e-litmus exam which is an aptitude test. then 2) is technical they ask all about projects related to algo and other detailed stuff. basically they test our logical skills so might ask u to write a simple program but wont be a compulsion. 3) is the hr. i dont know what criteria they follw but itz tough.. itz an elimination round as well and many students are eliminated from the same.. they ask you everything u write down on ur resume. so be careful with that just dont try to bluff with ur skills.. i didn't clear my HR.
