The process had 1 online test, 4 technical interviews then 1 HR interview. Unlike other online tests, this test had only technical questions, out of 60, atleast 50 were technical questions. the topics were DBMS, oracle-PL/SQL, OS, C, data structures. 1 or 2 quantitative aptitude and logical reasoning. The technical interviews were very interesting.., 1st interviewer made me write around 7 C programs, 4 of which were different types of implementing swapping of 2 numbers. Then sql queries, designing of database, os concepts etc... I told them that i cant remember theoretic concepts and networks, so they they asked only practical aspects n designing concepts, dint ask any network questions. 2nd interviewer asked questions on C, data structures, algorithms and OS..., he thot me some new concepts that i dint know. 3rd interviewer made me solve around 20 puzzles, mathematical and logical.., after that he asked me to write 30 unix commands which excluded 20 other commands already written by some one else.., i added only 10 here.. the 4th technical interview was taken after HR interview. he asked a few personal questions, then jumped to os concepts and dbms concepts. then he asked details of my project and internship. at the end, he advised me to learn a few concepts like inode, codd's law etc.. HR interview was normal, he asked all the usual questions like introduce yourself, why join informatica, wat u kno abt informatica, why to hire you, will you relocate abroad?, what did you want, if not an engineer, why dint you be so, etc... then asked to give example from my life which exhibits my decision making and adaptability.
