As someone who interviewed dozens of bootcampers I can give some insight. 1) Most of the bootcamps teach the basic of front-end, and a lot of them, teach by doing without explaining a lot of basic concepts. They are basically money grabbers and throw these people out of the door as fast as possible to get their money back. 2) A lot of the students are in for the money, not for the love of the job. Sorry, but it's tru…
I think this is the crux of the issues I had with bootcamp candidates. They were reasonably strong in the areas that they'd been taught, but there were gaping holes in their knowledge wherever they hadn't been taught. They could explain how to build a site with a Node backend and an Angular front end, but they couldn't explain why any of the decisions they'd been taught were good ones. And there were fairly basic concepts that were completely alien to them...of the 20 or so I interviewed, not one had even heard the term 'load balancer', let alone could tell me why I might need to use one. They had no notion of 'threading' or what it meant for a piece of code to be 'thread-safe' because they were only taught Node and its concurrency model. Even then, not one of them had heard of 'nextTick' or understood the event loop beyond the fact that it would call their callback function with the results. Their experience felt like a facade that was designed to seem impressive than it actually was. And all the areas where a developer with a traditional background would have thought, 'huh...I wonder how that works?' and then spent 2 hours figuring it out were completely unexplored.
This is why I think developers coming out of college are significantly more likely to be better at software development...not necessarily because the education they got in school was better, though I do believe an education starting with first principles and teaching you to figure out the solution from there is a better approach, but because the people that choose to study that in school are self-selecting for curiosity in the subject. They're the ones that hit something they don't know and go learn it rather being told what to learn. And they're the ones that spent at least 2 years following those tangents to get a more well-rounded education. Because any developer who only knows what they've been taught in courses, be they bootcamp or a traditional CS degree, is not going to have what it takes to learn on the job.
