msamp writes: After the dotcom bubble burst so long ago,when tech jobs were so scarce, I went back to school and finished my PhD in Physics. They lied — there really is no shortage of scientists. Before the downturn I was a product manager for home networking equipment. Since getting the degree I have been program/project manager for small DoD and NASA instrumentation programs. I desperately want back into network equipment product management, but my networking tech skills aren't up to date. I find networking technology absolutely trivial and have been retraining on my own, but hiring managers see the gap and the PhD and run screaming. I'm more than willing to start over in network admin but can't even get considered for that. Suggestions?
