Round 1

Test

Duration
120 Minutes
Test Sections
  • Section 1: Aptitude-10 questions
  • Section 2: Technical Questions(MCQs)-30 questions.
  • Section 3: Coding round-4questions.
Interview 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.
Interview 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.
Round 2

Technical Interview

Interview Questions
  • Question 1: Write the code for producer-consumer problem using mutex.
  • Question 2: Differences between Mutex and Semaphore
  • Question 3: Why do we need Mutex if we have Semophers.
  • Question 4: What is Deadlock.
  • Question 5: How can we prevent Deadlock?
  • Question 6: Explain the concept of virtual addressing and the allocation of virtual addresses during the execution of program.
  • Question 7: When would be the concept of virtual addressing comes into the picture(during compilation or run time)?
  • Question 8: Explain the roles of linker and loader during the execution of the program.
  • Question 9: Write the Test_and_Set program.
  • Question 10: Write the program to merge to sorted linked lists in sorted order.
  • Question 11: Write a program to find the duplicate in the array(only one duplicate is present in the array).ANS: best way-using binary tree on hash table.
  • Question 12: Consider we have large amount of physical memory.Do we still need virtual memory?What is the use of paging in that situation
  • Question 13: Time complexity of building a heap using linked list and arrays.
  • Question 14: How do you find the middle of the linked list.
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 3

HR Interview

Interview Questions
    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 .

      Test Technical Interview
      Round 1

      Test

      Duration
      60 Minutes
      No. of Questions
      20+40 questions
      Test Sections
      • Section 1: Aptitude
      Interview Experience
      Questions were asked from following topics:
      • VLSI (concentrate more) : setup time, hold time , propagation delay ( EE619 must be read carefully , recommended book : Rabaey )
      • Information theory ( unexpectedly ) : Information and coding theory
      • Digital & analogue circuits
      • Signal processing
      • No questions were asked from electrical portion.
      • A question was asked on cache memory concept and was almost asked in many companies.
      • There were questions related to flip-flops, gates, laches, FSM these topics must be thorough.
      Interview Tips
      This test was dependent on the amount of practice you've done. Since, for 60 questions 1 hour time is quite less so you must have your strategy under your sleeves. I was more towards technical side so I first completed the technical part in first 50 min. and then attempted 40-50 % aptitude portion. There were two profiles of R&D Software and Hardware engineer.

          Skill Tips
          For the interviews karumanchi is the best book. <br /> Presentation skills matters alot. No matter how much u know, presenating your knowledge in front of the interviewer matters alot. Speaking very fast during an interview may lead you to rejections (personal experience).
          General Tips
          It was challenging for me to get into this company. I was rejected around 10-11 times before i got placed in this company. So finding out the reason and to overcome it in the next company was the challenging task.

          For getting into this company you should have the knowledge of OS, Database,Networks and OOP concepts. "Job profile was software developer.

          The questions asked to me were related to OS concepts like deadlocks process and threads n all. From networks they asked me about the wifi drivers installed in your system. They asked about dynamic programming and they gave me one question to solve using dynamic programming. Then they asked me to write two more codes . From database they asked me about the errors which we will get if we do these things in the table. They asked me about the hashmap and how does it work and why it takes constant time in data retrieval. They asked me about the OOPs concepts and the virtual class implementation in detail. In short they asked me questions from every field.
