Its just a one day process , at least for not so senior positions , and by the end of the day you usually have their answer. It starts with same old boring apti/technical written test , quite easy to crack. Then depending on your profile , a profile specific test (like maybe a java program to write for my position) Then they have your technical rounds , again not so difficult to crack (age old java questions ) You may have another technical round , in my case i didnt . Then finally a HR round , which is just why u want to join etc. Then a meeting with finance dept where you can reject the offer due to low package :) . Go home ..

They took 2 aptitude tests and one essay writting. After clearing all the rounds HR told me , your profile skills not matching to our current opening. We will call you later. Very bad interview process.
