No the implication is that that's not how you manage female engineers, it's just how you manage male engineers.

He says later that female engineers will go get promoted into non-engineering roles soon enough anyway. The implication there is you don't need to worry about retaining them as engineers as they won't stay that way.

BTW this isn't an endorsement of either his views or his approach. I mean the general thrust of the presentation could be renamed "ways to stiff your staff".

There are bits of it that ring true e.g. the different motivations between newbies, lifers and the rest. The majority though is clearly intended to be provocative.

One could imply that if one were searching out reasons to get offended over a tongue-in-cheek powerpoint, which in fact features another slide specifically about female engineers.
