Context is key. Those jobs are his only qualifications.

I mean being 22 and having that work history is pretty relevant. How else are they going to make the case that he's nowhere near qualified enough for the position?

I would not hire this person as a repair technician based on that resume. Am I discriminating? Yes, in the same sense that all hiring discriminates for skills and experience.

I would never hire someone like this for risk analysis, risk abatement, or political communications.

How is this not completely fucking obvious to everyone?

Unless that’s his entire CV because at 22 yo, because what could he have done to merit such a critical role in the government?

All work dignifies but not all work prepares you for nation impacting decisions.

Thats really not the issue here and if you don't get that then I don’t know how to help you.

If he were the assistant director, or anything that's not a key leadership role, that might be true. But an agency head should have an appropriate resume and experience.
