Interview Preparation Tips
Round: Test
Experience: If you are from CS or CS related branches and if you are in no mood to take boring aptitude questions then probably this written test might be the one you are waiting for. The written test is easy for any one(any discipline) to crack if you are good at coding.1.Aptitude:The questions are easy to crack provided you understand the questions well.No need of in advance preparation required as most of them are puzzles.My suggestion:Solve aptitude within 15-20 mins as they don't concentrate much on your score in aptitude,however you need to cross the cutoff for aptitude which is generally high as the questions are easy.2.Technical Questions:Questions from Algorithms,Computer Networks,Data Structures,Database Management,Operating Systems(IMP).Most of the questions are just the basic stuff from the topics mentioned above.Also they concentrated mostly on pointers and structures(VERY IMP).IMP things to be noted to crack these questions:Given a c or c++ program with error,you should be able to tell whether the error is compilation error or Run time error-nearly 4-5 questions.Difference between compiler , assembler, linker and loader.Its better if you know the whole process of how the program gets executed if you compile and run the program.Concentrate on pointers in C.Again lots of questions on basic C stuff.Given a program you must be able to tell if there are any errors in the program or the program is error free,if there is an error,What type of error it is(Compilation error or run time error).Questions on different layers in Computer Networks(just basics).Questions on Process and Threads in OS(Very IMP).Time complexities of various sorts and searches in DSA.Time complexities on various questions related to Linked lists and binary trees. My suggestion:complete these 30 technical questions in 45 mins so that you can spend 1hr on coding questions which is very important.3.Coding Round: This is the most important one among the three and it carries most of the weightage for further rounds.If you crack this round with good score then you are almost through.Most of the questions are just the standard programming questions which can be solved if you are good at coding.You can use any programming language.Questions asked during my exam:
1.Write a program to print the no of digits in the binary form of the decimal number.
2.Write the functions to create a stack and to delete a node from the stack.
3.Write a program to return the Nth prime number from the Fibonacci series.
4.You are given a string and a number.Count the no of '-' characters in the string and return 1 if the count is equal to the number given or else return 0.
Tips: Don't neglect to practice some basic questions like finding GCD,LCM of 2 numbers, Fibonacci series,prime no,factorial of the given number etc.Some may waste their time during the exam thinking about how to solve these basic questions which is disastrous.
One question for sure on Binary trees,linked lists,stacks or queues.If you are asked to write only functions,write only functions,don't waste your time writing #include,main function and sort of stuff.You may think that you don't need 1hr to code these questions and you start wasting your time on aptitude.Believe me you will regret if you don't spend at least 1hr on coding questions as they care about good coding practices and time complexity of your program.
Duration: 120 minutes
Round: Technical Interview
Experience: During my time,they have shortlisted 14 members out of 80 members participated for the exam.Technical Interview may lost for about 1hr to 2 hr.They mainly target DSA and OS.They don't ask questions on Database generally.They may ask questions on Computer Networks but they didn't ask any during my time. Binary trees,heap,hash and linked list are the IMP topics.They concentrate mainly on the OS topics like Semaphores,mutex,monitors,Deadlocks,virtual memory concepts,virtual addressing concepts,paging and segmentation etc.Technical Round 1-they check your problem solving skills(probability,permutations),concepts in operating system,compiler design and computer networks,basic programming skills in C/C++.Technical Round 2-Algorithmic Round-questions from linked list,binary tree algorithms and concepts of pointers.They stressed mostly on the OS during my 1:30hrs interview.(say 1hr on OS and 1/2 hr on DSA).In Technical questions were mostly from Digital Electronics(a lot of questions from setup time and hold time and max clock frequency). Some very basic questions on Oscillators and Communication.
Round: HR Interview
Experience: 2 hr inetrview,25-20 min,main foucs wetehr you are ready to work in bangalore o not ,rest all simple stuff,dont show you have any relocation problem,then it is esay to crack,remember hr was also deciding factor so dont take it lightly.In cse out of 8 hr. they took only 3 so it was also having the weightage .Generally higher pointers were chosen .
