Informatica interview questions

6 Rounds. 2 Written + 3 Technical Interviews + 1 H.R. First round has objective questions based upon Data Structures, OS, C. Only technical and no aptitude type questions. Second Round has subjective questions. You have to choose from either C or Java. I chose C. Questions mostly involved pointers and memory allocation concepts and a few algorithmic questions as well. You are expected to point out errors/ predict outputs and also give a detailed explanation for your answers. This round is very important. Do well on this one and your chances of success will increase exponentially. Also most of the eliminations take place after this round. Interviews covered C++, DS, OS, DB Concepts, Projects,and algorithms. Overall level of questions was above average. Prepare your basics well.
