There are some other common reasons, apparently so far not mentioned in this thread, for job ads with a list of detailed qualifications nearly impossible to satisfy: First, the ad might be only to satisfy some legal or bureaucratic purpose and not to help fill a real job. Having the requirements be nearly impossible to satisfy helps reduce the number of responses as desired. Second, the ad might have been designed to give the employer plenty of excuses to reject people for whatever unstated reasons they have in mind. So, maybe they don't want to hire anyone in set A they have in mind so ask for five years of HTML5 experience and use lack of that experience to reject anyone in set A. Likely real hiring in organizations good to work for don't use such absurd ads. Such ads bring up a fundamental problem: The worker that happens to have so much experience that they can respond to a nearly impossible to satisfy list of 'skills' likely has many more related skills and, really, is quite highly experienced. So, such a worker is likely more experienced than the people hiring. So if the less experienced people hiring have actually done well enough in business to be able to pay a new employee, then the more experienced worker should be able to do still better starting their own business! Or maybe the worker should do anything to get an interview with the company, see what they are doing, and then start a company to compete with them! There is a related point: Such a worker will have to have at home his own computing, laptop, desktop, servers, and good Internet connection. So, really, he must already have nearly everything but a good 'business idea' for bringing up his own Web site and, thus, starting his own business. And in doing this work, he gets to use the tools he already knows or ones he would like to learn instead of the tools someone else wants him to learn and use. Likely good companies are not hiring via such ads but are hiring via Linkedin, job fairs, networking, open source code samples, etc. The real solution here is due to Darwin: Companies that waste time in silly recruiting efforts are at a competitive disadvantage and on the way out of business. So, here is the good news: If some companies can remain in business spending time, money, and effort in such silly, wasteful ways, then think of how much money there is to be made if cut out the waste! One final point hackers should understand: The 'suits' should be afraid of the hackers and they are!
