Process

I applied online through the MathWorks website.

Received an email in around two weeks for an online HR-based interview. The interview had the 5 basic questions given on Glassdoor.

Shortly thereafter, I was scheduled for a technical interview. The technical interview had 29 questions from:

  • MATLAB
  • One additional programming language (I chose C)
  • One area (I chose Control Systems)
  • Linear Algebra

Questions

Some of the questions were:

Control Systems:

  • How is an LTI system stable?
  • What are eigenvalues?
  • Find stability of LTI system.
  • Find eigenvalues.
  • Phase margin?
  • State-space formulation.
  • Observability, controllability.
  • Rank of a matrix.
  • Control canonical form.
  • Lyapunov stability.
  • Find poles of a system.
  • What is a Bode plot?

Math/Algebra:

  • Solve an ODE.
  • Difference between ODE and PDE.
  • Solve a limit involving indeterminate forms (using L'Hôpital's rule).

Programming, C:

  • malloc
  • const
  • Recursive function. Give an example.
  • Difference between passing a pointer and a variable to a function?
  • Null pointer?
  • Structures?
  • Difference between structure and union?
  • ptr++
  • Some simple for loop questions.

Programming, MATLAB:

  • Defining folder paths.
  • Clearing and importing variables.
  • Making an array of numbers divisible by 3.
  • Concatenating strings.

That's pretty much it. In total, there were 32 questions. I got 27 of them right. For the remaining questions, I either didn't answer or gave a general idea since I could not recall it at the spur of the moment.

From other reviews, there doesn't seem to be a lot of hope, but let's see. Fingers crossed. Hope this helps.
