I know what a "soft skill" is, but the article said "hard and soft technical skills" and I don't know what a "soft technical skill" is which I think should have been defined so we all know what's being talked about rather than guessing which is what I did. Another comment suggested that "create a good architecture for a complex software project" can be a soft tech skill. I don't see how this is gender-biased other than the number of males in the profession largely outnumbers women so the answer to both is more likely male.
