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 Few questions that were asked in technical interview are(boundary conditions were given much importance): 1) find level sum in a tree 2)bit wise swap (2 bits swap) 3)2 stacks one queue implementation 4)indexing 3-dimensional arrays and its dynamic allocation 5)dynamic allocation/deallocation of 2D & 3D arrays 5)inter process communication 6)given pointer to node, delete that node 7)Implement heap 8)implement malloc 9)asked to draw E-R diagram for some scenario 10)Employee payment class design 11)given 2 strings, delete all the occurence of characters in string 2 from string 1. 12)remote procedure call 13)socket programming 14)semaphores and multithreading, with example (real-time) 15)hash map (top 100 transactions per day) 16)write query to find top 10 employee whose salary is maximum 17)write query to find Employee whose salary is second maximum 18)Count smaller elements on right side 19)P THREAD IMPLEMENTATION 20)STORAGE CLASSES 21)DISCUSSION ON PROJECT 22) Discussion on private constructors in singleton class

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.
