IMO this makes a strong case for working with small companies. Big companies are relatively risk averse and will look for external validation of the candidate - certifications, degrees, impressive prior experience, etc.

It's much easier for a young person lacking experience today to approach a small business and successfully pitch them on an internship or some contract work. A large corporation is too hamstrung by HR, by policy, and by its own approval chain, to take advantage of things like this.
