Since the lack of talent is a huge problem, there are tons of _academies_ that claim to be producing developers in just a few months. This generates a lot of people with no experience, close to zero knowledge but yet eager to join the industry. A viable strategy for companies is to hire as many of those as possible, hoping that there are just a few diamonds there. That's the main reason Jrs are terribly underpaid. If one prooves to have potential - it is not uncommon to have a salary doubled in a few monthsm, otherwise other organization might snatch the person.

I had interviewed a little more than a hundred people for regular and senior roles only to eventually give up and train a couple of juniours.
