My company at least used to bring high school students to the company for a women in STEM tour. I believe they stopped it. I have no idea if it worked or not. It certainly didn't work for the company since we weren't seeing any of them join after college.
At least in the case of an intern we had, she went to some other company. Which in fairness, was the better choice. In the conversation we were having, the manager even told her to go to any other company if she has the option because they will pay more. One of the best managers I've seen and he wasn't even my manager. Of course he left for another company shortly after.
Yes, this is one of the funny things about DEI discussions to me.
In a work conversation, a coworker mentioned recruiting more women to work for us. I basically said we're never going to win against FAANG companies competing for the limited pool of women software engineers, and he didn't have a response to that.
Some companies may not be diverse because they don't want to hire from under represented categories, but because candidates from those categories have better offers.
