I am guessing that the current state of the job-search algorithms is good enough for them to not want to "improve" it. And on another note, without allowing a little bit of error, certain things that would only happen by chance would just not happen. In a convoluted way I am saying that the job seekers' AI seems to be doing as it is told and performs as well as it is funded to do... And, in today's job market, which is the seeker who is the chooser, I am not surprised that rcruiters are pretty desperate.
