If you hire someone that knows the work but just needs experience you will find yourself working with someone who is engaged and enthusiastic. If you hire the latter you will spend all of your time holding their hand.
A qualified junior is someone who can take a well-specified, narrowly-scoped, low-risk task and execute it in a reasonable, not record-breaking, amount of time. They fundamentally need someone to hold their hand, if only to ensure that the task is truly well-specified and narrowly-scoped.
If someone has any experience, and they're interviewing for junior roles, that should raise eyebrows. It's not an automatic disqualification - shit happens, people find themselves working for abusive bosses, whatever - but having any experience whatsoever should come with it a lessening of hand-holding (and its bureaucratic expressions in workflow).
