You could hire someone who knows how to learn. You could mentor. You could groom. You could train. Find someone who is 80% of what you are looking for and then get them up to 100%. No? That's not in the budget? You require absolute perfection right out of the gate? Well, it might be hard to find that person. And it's only going to get harder.
You have touched a very important topic. Computer companies did train employees in the 60s and 70s; and, their internal schools were top notch. The semiconductor industry also trained engineers in the use of their products, particularly for the more esoteric devices like bit-slice elements and register files and such.
Companies would be surprised at how effective those programs would be.
I forgot to include in my last post that I had magnificent mentors. One used to work at Bell Labs. One was from Lockheed Aerospace. I even had very quality mentoring from one of “Grace’s Girls”. The best tutor during my undergraduate studies was an IBM CE; and, he was trained at a number of IBM schools.
Yes, it’s insane. I’ve seen listings demanding people have 10 years experience with a technology that’s only 5 years old. It COULD be a trick to make sure you KNOW that it’s only 5 years old, but these “I demand everything” listings are quite popular.
