There is an alternative explanation to the biases people are seeing here, unfortunately, and it would render gender and age confounding variables. It's known that Valley tech firms of the type studied in this paper have a large left wing contingent amongst employees. We know that being female with a degree correlates quite well with being left wing, as does being young. In contrast being an older white male correlates somewhat with being conservative. If the actual discrimination here is against "people likely to be conservative" - which is absolutely likely to be happening given what's going on in these firms - then setting quotas for gender and age wouldn't be addressing the underlying problems, only symptoms.
