I came in for an interview for the EDG Engineer position. First, note that an EDG Engineer is basically a glorified customer service representative, which turned me off to the position.

Anyways, during the interview, they asked standard math and MATLAB questions, similar to previous posts. However, they asked some DSP questions I didn't 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 didn'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. 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!

Pole-zero plot?
