I applied through university. The process took 2 days. I interviewed at Informatica (Trichy)
Interview
Suggestion to the company: Informatica, try to have Online test on MCQs and Coding together. By which you can get the people with really good problem solving skills along with good subject knowledge rather than subject knowledge alone.
Following are the process schedule:
The interesting part in this Process is the PPT by HR. He was such a energetic person with good skill of crowd management with smiling face and always cracking jokes and always wanted us to be more interactive.
Then comes the first round, which is obviously the Online test which contains MCQs from core parts of Computer Science like DS and algorithms, OS and DBMS.
Then who are getting qualified in this round can attend the Coding Round (2nd round).
4 Questions for coding round were very average questions from array, linked list, trees, graphs, heaps. and some can be solved by having experience in dynamic programming.
And the third and fourth rounds are also the average ones with questions from graphs, heaps, linked list, stack, trees (basics and also SBBSTs).
I have prepared for the company for long period, i lost the chance in the first round itself. Even i'm good in Data structures and algorithms i had no chance to show my skills to the company people. I did the Online Test very well but unfortunately my name was not called out for coding round. I lost one of the good company.
All the best people for your future.

I applied through university. The process took 2 days. I interviewed at Informatica (New Delhi) in Sept 2015
Interview
It was a on campus process.There were 7 rounds in total.
1st Round: Online Exam - Consisted of 4 sections one for each of Ds algo,DBMS,OS,aptitude.
2nd Round: Subjective Test - Consisted of 3 sections.One section consisted of questions from oops and we have to tell the error in the code and the correction.Other 2 sections were mainly from DS and algo and level was easy medium.
This was followed by 4 technical rounds and 1 HR round.
Overall the process was quite long but they conducted it very well and the interviewers were very friendly.

Interview Details –
-2 online elimination tests: 1 Objective test(C,C++,DBMS,OS,DS), 1 Coding test(It basically consisted of 10 questions, Two coding questions(DB related scenario), some code-debugging questions, and some DS questions(tree, linked list)etc.)
-3 technical interview rounds(some had 4)
-1 HR interview
