> Certainly not at a big corporation where there should be enough of an employee pool to have it at least somewhat reflect the general population of the region.
That is a drastic oversimplification.
The employee pool can only hope to be reflective of the pool of those who seek employment at that company and are qualified.
Which can only hope to be reflective of the employee marketplace for that industry at large.
Which can only hope to be reflective of the pool of people who have the right education and experience.
Which can only hope to be reflective of the people who graduated with the appropriate degree for which they're hiring (in most cases).
Which can only hope to be reflective of the people who got accepted into those schools.
Which can only hope to be reflective of those who chose that education/career path to begin with.
Which can only hope to be reflective of the population that sought out things like math and science when in secondary school.
Which only then can only hope to be reflective of the general population.
At each step there is filtration. It's affected by people's upbringing, their role models, what advertising they were heavily exposed to as impressionable children, who their friends are, who their teachers were, whether computers were popular when they were going through school, the list goes on and on.
The problem of under and over-representation in tech is a real one, but pretending that companies just need to somehow make up for all of this filtration, at the very very end of a literal lifetime-sized pipeline, is folly. Outreach needs to happen much, much, much sooner than that. At the end of the day, companies are at the mercy of who's in their hiring pool.
