I think it's important to differentiate that it depends on the company and the field. For lack of a better phrase there are sexy companies and not so sexy companies in the IT world. They get different people applying to them and they have different wants. If you are looking at doing R&D at a startup software company, the competition is going to be far different than working at a medium sized independent insurance company
Yes, but the 50% ratio is for those that aren't doing R&D or the like. They are literally asking for stuff that has been done 912834902384902380492349023 times before from an IT perspective like a standard OS db cluster backing a web app which is behind a CDN+Load Balancer combination.
