I applied online. My major is Mechanical Engineering and my area is control and measurement. I have experience in control theory, signal processing and programming(such as c++, but not as strong as CS student). The first round interview, which is video interview, is general HR questions. I found that my question is the same as other applicants. I will briefly introduce the video recording process. This process will give you plenty of time for preparation and warming up, so do not be nervous. At the beginning, there will be a introduction video of the position in MathWorks. I recommend you of watching that video and eliminate some of your nervous feeling. Then there would be a hardware test section in which you can test your laptop camera and record a sample video. I also recommend you of doing this since this will give you a sense what do you need in the next real interview, for example, adjusting your volume, pitch, etc. The questions are just like: Why you fit this position? How you will handle multi-tasks? What is you GPA? Do you need sponsorship? My feeling is that you will go through this round easily and they arranged a technical phone interview on 11/14/2014. I am preparing that. One thing I worried is that I don't have deep theoretical background about programming since my background is Mechanical Engineering. The topics will be the following six: • Basic math - calculus, differential equations, and linear algebra • Programming concepts  --  programming constructs, style and logic, OOP concepts • One programming language – C , C++, or Java (C++ or Java is recommended) • MATLAB  --  basic MATLAB syntax, commonly used functions and documented concepts One specific engineering discipline that best fits your background. Options include: • Control Systems-  classical control, modern control, and non-linear systems • Signals Processing- concepts such as aliasing, convolution, and transforms • Embedded Systems- Real Time Operating Systems, Scheduling, and General OS Concepts I asked a friend who is in MathWorks, he said probably they will cover all these topics...

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
