A few years ago, I'd say web dev. I'd hire a junior web dev fresh out of a boot camp with only 6 months of experience at 60-80k.

Today, my company won't allow it, and I'm fighting to get new devs. We won't even take a junior without a bunch of core competencies, things that will take at least a year to pick up. But even if we did, there's a huge pool of applicants who want in.
