Discussion on: You're not worth hiring unless...

I agree that these qualifiers are absurd and dangerous. I won't allow any such in my own company's hiring practices.

When I encounter these I am interviewed, I have an answer ready, however...

I've had to come to terms with the impracticality of learning everything, even though I want to! Even if I learn something, but I never use it, it just winds up decaying in the back office of my mind. I've had to adopt a policy of only learning something once I need it for my current task. Thankfully, it only takes me a few minutes to do this, so it works out well.
