>I've often wondered why so few companies make a concerted effort to seek out talent rather than credentials. Have most companies not realized that the two aren't directly related? Are they too lazy? Do they have no confidence in the ability of their hiring managers? Do they lack the resources to train new employees?
* In general, I think there has been a strong trend away from investing in people, to treat them as interchangable cogs or simply farm out as much as possible. I've seen larger organizations which almost seem scared of having exceptional people, or more specifically allowing them to do exceptional work. It's actually seen as a kind of liability, that a great person could generate leverage to effectively demand more money or leave and take unique institutional knowledge with them.
* Assessing "talent" costs time. The time of reasonably talented people you are or will be paying, in some form another.
* Unless you find a way to turn it into an automated, repeatable process, the decisions made are subjective and subject to all manner of criticism and allegations. This might not rate in a startup, but once you're large enough to have anyone titled "hiring manager", I expect these things are going to be relevant.
* Scale is a problem. If I put out an entry-level job I'm gonna get 500+ applicants. Reduce it to something almost criminally narrow (You already know who you're going to hire, but you have to go through the motions and make the selection defensible) and I'm still looking at 100+.
* Not sure what exactly you mean by training. It's hard enough to find people who can drop into a new environment and apply their existing skills immediately. Finding people who are so smart and capable that they can drop and learn skills while applying them would be that much harder.
