I know technologies A, B, and C well-enough to use them to make a thing that is good enough for people to pay money for, i.e., not a bootcamp copy-paste thing.
"Tech Company" is looking to hire someone that knows technologies A, B, and C to use to make a product that's also intended to make money (allegedly).
If that's not good enough, I ask again, what is? What do you really want in a prospective junior developer?
The guy is making a web app which other people want to pay for, looks like just about the right height for a bar, and I'd say not low at all.
