Are there actually studies that show that the interview process rather than the pipeline is the issue? At my previous job we ended up making an offer to every female candidate who made it to the phone screen. This wasn't because we preferred them because of their gender but because they were really good. Many men never even made it past the phone screen. We still ended up with a majority of men on the team.
