In the last months I made experience with some courses on Udacity and Coursera and I found it awesome.
As I know:
Udacity is a "Headhunter".
Some smart students which had finished the more sophisticated courses very well were called from Udacity for new job opportunities.
You will also find its way in their FAQ:
Udacity - 21st Century University
Now Udacity announced a course on "Functional Hardware Verification" in collaboration with Cadence.
See Udacity - Functional Hardware Verification Course (cs348)
I think, Cadence is searching for new talents the other way!
