When actually what a person needs when learning a subject is exposure through different methods and ways, and of course, time!
Otherwise they'll be a one trick poney. I know so many people that did different bootcamps and my experience with them is similar, they need a lot of extra training because everything they've learned was in a very linear way. Sometimes it would be better if they would start from scratch and forget what they've learned in the bootcamp.
Every entrepreneur is trying to find the next method that will teach coding to beginners in no time, but nobody is focused on actually building people from beginners to experts.
Some platforms like pluralsight tries that, but they are mostly boring courses.
In the end we have a lot of competitors in the same space, when exactly zero are worth to subscribe long-term(like pluralsight, but it's fucking boring).
Just my 2 cents.
