I would urge everyone to consider opportunities outside Ciena. If you are seeking far better pay (+ 50%), more scope for career growth and a better culture that would treat employees like they should, that would be a no brainer.
PM and the cool-aid drinking team under him are commanding a rudderless ship that is big on PR, but severely lacks implementation; a continuation of the last 6 years of how how this bay area team has been run into the ground.
There is 0% probability of building anything valuable (revenue wise) in the virtualization space if Ciena cannot attract & retain top talent. I know 15+ top-performers leave in the last couple of years for Amazon, Vmware and Google.
