Unreasonable job requirements

I am sure that everyone has encountered these at some point. Being a recent graduate, you come across a lot of job postings during your job search and you see some crazy requirements posted by companies. Specifically I remember coming across an entry-level HR position that asks for 3 years of HR experience. Wait a minute, this company either thinks that their entry level is above other entry level jobs or they have another classification for the people that are entering their HR department without any experience. Intern or temp job titles come to mind. 

Last week I went into a dollar store and saw a job requirement for their store clerk position – it read: “5 years of retail experience required”. That’s excessive in my opinion, but there may be something else attached to that figure. Competence wise I am certain that 1 year of retail experience should qualify anyone to work at all stores that do not require product knowledge. This job certainly appears like one of the jobs that should not require product knowledge. They could be looking for somebody more “mature”, which is a more covert way to select people above a certain age without getting in trouble for age discrimination. And I have a problem with that.  I feel like the youth are already getting squeezed out of entry level jobs, and to discourage them from applying is wrong.
