I don't think it means much in the big picture but it does seem to be a reasonable example of a company where the hiring process is fair, gender-wise, from start to finish. The only problem is that a mere fraction of the applicants are women.

And it makes it easier to believe that, at companies unable to attract and screen that many candidates, they may get no qualified female applicants, period. It lends plausibility, even if it's not actually proving anything.
