But then you run the risk of having someone who knows the answers to every question on the exam, but couldn't actually perform the job without lighting the server room on fire. That can't be better for your business than what you're saying.
Would you want someone performing surgery on you who can recite every step of every procedure, but has never held a scalpel?
And I have witnessed a 20 year network veteran switch off spanning-tree becasue “I never use it”. Had he attended day 1 of any networking course, he would have had a much more rounded idea of the havoc he could have been wreaking. And yes, not one redundant network link in his whole life. “I’ve always done it this way” says the voice of experience, and he thought VLAN’s were witchcraft. If I had his luck, I’d have won the lottery… twice… I will say that I came across this guy in the late 00’s which might explain why he got away with it but even so…
Personally, I have conducted quite a few interviews of candidates who claimed both certification and experience yet were unable to pass a fairly straight forward practical test and as we all know, for I.T jobs there is usually a practical test. That usually weeds out the charlatans… as long as the person giving the test knows what they are doing, but that’s another story…
Same for surgeons too. They have to demonstrate competency along with contiinual professional development and are subject to performance reviews etc. The morbidity and mortality reviews that surgeons have are brutal, but I digress… Of course surgeons don’t have to re-do their medical degree, but then a two and a half hour test every three years for a job where one has decades of experience is hardly onerous.
Having held certs for many years I condsider re-certifying as another part of my periodic performance reviews. What is wrong with having ones continued professional development monitored, examined and verified? Is this a bad thing?
In my experience, two things are true in the 21st century. Experience counts, of course, no argument there, and recruiters are looking for certs to get the candidate through the door. When having both is so easy, why would one object?
And to be clear, I’m not tryting to convince anyone to change their minds. If one doesn’t want to get certified for whatever reason then OK. It is an interesting discussion and I always enjoy debating with and hearing the opinions of fellow network engineers.
