Samsung Interview Experience | Set 32 (On-Campus)
  • Difficulty Level : Medium
  • Last Updated : 17 Jul, 2019

Samsung R&D Bangalore visited our campus (Eligible branches – CSE, ECE, EE, B.Tech/M.Tech with 7+ CGPA). There were 4 rounds:
Round 1: 3hrs Coding Round
Round 2: Pen-paper Coding Round
Round 3: Technical Round 1st
Round 4: Technical Round 2nd
Round 5: HR Round

Round 1 (Online Coding Round) – This was a 3 hours coding round in which we had to code 1 problem having 50 test cases. Only those students were selected for the next round who passed all the test cases.

Note – You can compile your code as many numbers of times as you want, but a maximum of 10 submissions were allowed to test on the given test cases.

Question: There was given total physical energy H and total distance D. Five pace information speed and corresponding physical energy was given. Find the minimum time that is required in order to complete total distance D making sure that some of the physical energy does not exceed H ( I don’t remember the question exactly, but it is something like this).

After this round, 20 students were shortlisted.

Round 2 (Pen-paper Coding Round) – This was pen and paper based coding round. We have to write the code and also calculate the time complexity.

Question: You have a bag containing only black and white balls . You pull out 2 balls. If the balls are of same color, then you replace them with a white ball – but if they are of different color, you replace them with a black ball. Once you take out the balls, you do not put them back in the bag – so the balls keep reducing. What would be the color of the last ball remaining in the bag.
This was not an elimination round.

Round 3 (Technical Round 1st) – Before the start of the interview. The interviewer had thoroughly gone through my resume.

  1. As I mentioned SQL in my resume. He asked a query “You have a student table having 3 attributes student_name,subject and marks. Find the subject-wise maximum mark of students. Arrange the subjects in ascending order and marks in descending order”.
  2. He asked about memory layout of program, function pointer, Types of pointer, And Pointer basics.
  3. He gave me two codes to find out the error (that was related to the dangling pointer and memory leak).
  4. Optimize the code that was given in pen-paper round.
  5. Reverse the linked list without changing it’s structure (full working code was expected).
  6. Given a singly linked list and a position, delete a linked list node at the given position.
  7. Write a program to swap two numbers (I gave four approaches).
  8. Check a given number is palindrome or not.
  9. Find the majority element in a given array (if the integer size is 32 bits).
  10. Questions related to SJF and SRTF.

Round 4 (Technical Round 2nd) – At the start, He asked me to introduce myself in 30 seconds mentioning only technical part.

  1. Write a code for segmentation fault.
  2. Write the code of CPU scheduling Algorithms (LIFO,FIFO,SJF) in O(1).
  3. Can multiple CPU scheduler work at the same time?
  4. Tell the difference between NULL and NIL.
  5. Level order traversal of binary tree.
  6. He asked about STL and OOPs concepts.

This round was not good for me, I hardly answered 2-3 questions. But my previous rounds were excellent so they called me for the HR Round (don’t lose hope if one of your round is not so good).

Round 5 (HR Round) –

  1. Tell me about yourself.
  2. He started with discussion of my projects which I have mentioned in resume (prepare the projects clearly. If you are using any standard library, You must know the implementation).
  3. Difference between DFS and BFS.
  4. Difference among Tree, Linked list and Array (Searching, Insertion and Deletion).
  5. Check if multiple header files are included in program?
  6. Sort the stream of integers.
  7. If Google and Samsung both are offering the job at the same time, which company you will join and why?

And then he asked me if I had any questions. I asked him three questions:

  • What is the mean of “Cutting Edge Technology”?
  • How the Samsung describes it’s vision “inspire the world, create the future”?
  • What are the health care products on which Samsung is currently working on?

Tips : Know everything you have mentioned in the resume. And, as they will be checking your thought process. Never stop or give-up on any question. You must have deep knowledge of pointers.

If you clear the online coding round, there is 90% chance of selection.

Finally 8 students were selected and I was one of them.
