Companies hire the best people for the job, male or female.   Mandating quotas is ridiculous.  I'd let a position sit vacant to hire the best person, rather than just because of their sex to meet some arbitrary imposed quota.   I do believe that there should be mandatory "blind" screening for initial interviews, whereby you don't know male or female, just qualifications, education, skills presented.   I use this approach for all hires and I found that it takes any unintended bias out.   I also only have first interviews via phone calls, to further take out the bias of age, weight, appearance and focus on communication skills.   I've even hired without seeing them for certain roles.
