I get that she was actually a nice person who simply didn't know when .NET was invented. But I do not accept that she made a harmless and easily fixed error on the job requirements because of this.
Frankly, I'm not that concerned that the job requirements demanded more years of .NET experience then it was possible to have. I am more concerned about all the other requirements that were listed on that job description which were just as wrong but in a way that was not obvious.
Consider the analogy to all of the exonerations of convicted prisoners we have had since DNA analysis became possible. The minor problem is that hundreds of innocent people were held in prison for years before DNA analysis proved they were innocent. The bigger problem is that we have now demonstrated that the legal process has a significant rate of error, meaning that there are tens of thousands of innocent people serving years in prison whose cases didn't happen to permit exoneration by DNA.
That line in the job requirements that specifies you must have a college degree -- is that unnecessarily excluding a lot of qualified candidates? The general tendency to request more expertise and years of experience than are really needed -- is that driving off candidates with lower levels of self-aggrandizement? If it is, does that have anything to do with the deplorable number of women succeeding in our industry?
Asking for 12 years experience in Kubernetes isn't just a silly error: it is an unmistakable sign of a much deeper problem.
