Yes and no. Requiring a computer science degree is a fairly reasonable restriction to place on hiring, since it (at least on its face) correlates strongly with qualification for the job. However, requiring all your employees to go on a bro's ski weekend trip, or serving your free dinner at 8 PM every day when none of the women with families can stay for dinner, may have a disparate impact on employees without any correlation to their work performance. To turn up the contrast and make a semi-absurd argument, one could say, "We don't discriminate on the basis of religion, but we ask all applicants to recite the Lord's Prayer from memory in their interview. Strangely, we never seem to hire any Hindu or Muslim applicants." OK, that's absurd, but what if you only recruit at universities that have extremely low female:male graduation ratios in their CS programs, when there are other programs with better balance? That's certainly not discriminatory on its face, but it has the same result as if you had discriminated overtly. Sexism may not be the right word (and I didn't use that word), but I do think it's important to look at the results of your policies and environment in totality to determine if you are treating women equitably. This is certainly the standard that the courts use for evaluating things like voting regulations -- look at the recent rulings on North Carolina's voting laws: actions like curtailing the number of weekend voting days that do not mention race at all are clearly crafted to reduce participation by black voters.
