I came in for an interview for the EDG Engineer. First, note that an EDG Engineer is basically a glorified customer service representative. That turned me off to the position. Anyways, during the interview they asked standard Math and MATLAB questions, similar to previous posts, but they asked some DSP questions I didn't really do too well on: convolutions, pole/zero plots, fourier transform, circular convolution, nyquist sampling theorem, and some other stuff i don't even know the name of. They don't respond or say anything during the questions, which I think is BS. Afterwards, they asked me for references. Then after ALL that, they said " Not a good match. " I spent so much time and they didn't have the decency to even tell me why. I am certainly bitter, but this job seems pretty one-dimensional and you only get to work on things if there is a client base out there. Good vacation days though!
