J'ai postulé via la recommandation d'un employé. Le processus a pris 2 mois. J'ai passé un entretien chez MathWorks (Los Angeles, CA) en mars 2015
Entretien
First the standard HR video interview followed by a technical phone interview.
First HR interview is same as mentioned in glassdoor.
Technical phone interview- Similar to other questions mentioned in glassdoor with some new.
Waiting for the response on technical interview.
Questions d'entretien [4]
Question 1
---DSP
-What is PSD and what is its relationship with autocorrelation?
-h[n] = [1,2,3,4,5] i/p frequency= 100 HZ, system is LTI. what is the o/p frequency?
same i/p frequency, now h[n]= [1,4,9,16,25], what is o/p frequency? I answered it and he asked how?
-What is the relationship between bandwidth and time duration?
-Given a signal spectrum that is valid in range of -pi/2 to pi/2. What is the range of frequency when the signal is oversampled by a factor of 4?
-What is the relationship between Discrete Fourier Transform and Z-transform?
-y[n] = x[n^2]. system stable? causal? linear? I answered it then he asked how?
---C++
-What is virtual constructor?
-What is virtual function?
-Given a code with destructor and asked for the output?
-Can you define a function in c++ structure?
