For the industry where I'm based now, we look at the experience and all the technical skills the candidates possess before anything else.
As engineers, extra set of technical skills is crucial in order for them to climb higher in the corporate ladder.
Back to my own department, my big boss only has a HR professional cert, without Degree or anything. Yet, she is so up high now. Her experience in HR fields is undeniably strong.
Another colleague, 10 years ago was a secretary and decided to make a change in her career life - to take up HR. She is so successful these days that she gets outstanding rating in every appraisal. Truly a known great asset to the company. She doesn't even have any proper cert to begin with...
In my department, only my boss and myself have a Degree in HR. Having said so, my boss gets to where she is today is based on her experience in various HR functional fields, her qualification is probably important but that's not really a hiring criteria.
What I said above is based on my own experience, in my company and the industry I come from - telecommunications. Please don't get me wrong, I'm not generalizing.
I'm just in my third year of working as a HR practitioner.

Yup. I personally know a few examples like this too and I am in IT and Telco industry too. But the real challenge only comes when you try to apply for job in a different company when you are at that level with simply a cert or diploma
would you hire a senior manger, director or VP with that qualification though they may have the experience? Maybe... But again as I mentioned, competition will be tough with many good candidates with solid experience and higher qualifications. I'm not saying that it's impossible, but look at the bigger picture especially when advising people. also, hiring senior management is a different game altogether :-)
