Bootcamps used to be strictly for military types, but in the past decade, they've become a tech industry phenomenon. Tens of thousands of tech professionals have graduated from bootcamps over the last decade, most of them freshly-minted developers. A new crop of bootcamps, though, trains students to work with data.

Some require candidates with undergraduate STEM degrees; a few, like the New York Data Science Academy, favor PhDs in STEM fields. This reflects data scientist job requirements, which can be extensive.
