I got a call after I submitted my resume at the career fair at my university. The first call was about my availability, explaining my projects and why I choose to apply at Mathworks. They then scheduled the second call which was a technical interview. There was 5 sections in 2nd round, 1.Basic math - calculus, differential equations, and linear algebra; 2.Programming concepts -- syntax and how languages work; 3.One programming language – C (recommended), C++, or Java - if C++ is selected, you must understand syntax and structure, compilation and OOP concepts; 4.MATLAB -- basic MATLAB syntax, data and programming concepts; 5.This section is a choice between signal processing, control systems, computer science and one more field(i don remember). I choose Signals Processing (concepts such as aliasing, convolution, and transforms); Signal Processing: 1. What is aliasing?? 2. State Nyquist theorem 3. Explain over sampling and undersampling 4. Explaing linear time invariant systems 5. given an input x[n] and output y[n], find out whether y[n] is linear and/or causal and/or time invariant 6. What are FIR and IIR filters? 7. questions related to z transforms, fourier transform, dtft, dft MATLAB 1. Difference between function and script 2. workspace of both 3. difference between a*b and a.*b 4. initializing an array 5. find the numbers between 1 to n which are divisible by 3 6. how to concatenate 2 strings without using an in built function 7. how to find the transpose of a matrix Basic Math 1. rank of a matrix 2. eigen values and vectors 3. orthogonality 4. null space of the vector 5. projection of a vector onto another Programming language and concepts 1. difference between call by value and call by reference 2. difference between const and define 3. difference between * and & operation Felt the interview went really well but dunno what they were exactly looking for, I got a reject
