I applied through university. I interviewed at MathWorks
Interview
First, HR phone interview. It was very simple. Just some behavioral questions. Then they gave me a technical phone interview. It lasted about 1 hour. The interviewer was keeping asking questions one by one. However, all the questions are very basic but detailed.
1. DSP:
1) What is IIR and FIR? Difference? Given an example to judge whether it s IIR or FIR and
why?
2) What is z-transform? She gave me a sequence and asked me to get its z-transform
3) Given a sequence, judged whether it is stable or not. Why?
4) What is the relation between the unit circle and stable?
5) I do not remember other questions, sorry!
2. Math:
1) Calculate the eigenvalue and eigenvector of a given 2-by-2 matrix.
2) Calculate the inverse of a given 2*2 matrix.
3) What is the null space of a given matrix.
4) I do not remember other questions, sorry!
3. C:
1) What is pointer?
2) What is typedef used for?
3) What is the difference between malloc and new?
4. Matlab:
1) How to merge two strings?
2) What is the difference between function and script?
3) How to access the variable hide in a function?
Good luck!
