MathWorks Interview Experience (EDG, Oncampus)

Round 1 (Online)
Time duration – 1Hr 30min
Number of Questions – 45
Sections

  • Mathematics (6 MCQs) – Aptitude
  • Computer science (10 MCQs) – OS, DBMS, Networks, DS, Algorithm
  • C (7 MCQs)
  • C++ (7 MCQs)
  • Java (7 MCQs)
  • Python (6 MCQs)
  • Coding (2 questions)

1. Given a sequence of binary numbers (0, 1) of size ‘n’ in which every 0 represent a decrement to the sum and every 1 represents the increment to the sum. You have to find the minimum possible value of ‘k’ such that the sum of the first ‘k’ elements is greater than the sum of remaining elements.
The initial sum for both the half is 0.
Eg.

  • given sequence – 101011
    The minimum possible value of k – 6
  • given sequence – 1001001
    The minimum possible value of k – 0

Instructions- From the above-mentioned sections- mathematics and computer science sections were compulsory. You have to choose any 2 sections among C, C++, Java. Python section was a bonus. For coding questions, you have to choose language among c, c++, java. Both questions need to be implemented in different languages.

Round 2 (GD – 15min)
Group discussion round was the elimination round. Every discussion was among 10 students. Topics were related to politics, demonetisation, teamwork etc.

Round 3(Technical Interview – 1.5hrs)
Started with introduction and then briefly covered all the projects mentioned in the resume. Some basics of machine Learning (as my projects were around it).

  1. Compiler and operating systems basics.
  2. Size of integer (how and why).
  3. 32-bit machine Vs 64-bit machine.
  4. Word size, Bus size.
  5. Padding.
  6. INODE, FAT.
  7. OOPs concepts.
  8. Output questions- Good knowledge of pointers were tested here. Give outputs along with reasons.
  9. Sort a given Queue without extra space.

Round 4(Managerial Round – 1hr)
It started with an introduction and then followed by a few situations based questions. All the following questions need to be answered with a real example from your life.

  • How do you do time management?

  • And many more.

Round 5(HR Round – 30min)

  • Introduction
  • Why Mathworks?
  • Location preference.
  • Family background.
