The engineer who already has a job at a random company has a known skill level and growth trajectory. The engineer out of a good school has an unknown growth trajectory. Conditioned on the accomplishments of alumni at the school and the (subjective) acceptance bar of the school, the new grad engineer could have a much steeper growth trajectory than the established one. Silicon Valley got this right on the money ironically [1]. If you have nothing to show, people assume a potential future ability level rather than basing their decisions on your actual ability.
