This has happened to me once... they told me how I could improve my graphic design portfolio. It was a smaller design firm and it was the owner, so he had the time to do that.. even at a medium size firm they probably wouldnt offer

I have even emailed the interviewer back a few times asking if there were ways I could improve. Crickets.

But my longest jobless stint was 2002-2004. I counted that I had sent out 850 resumes... and I finally got a break. Its cheesy but "every storm cloud runs out of rain"

Good luck on your search!
