A general practice of many coding bootcamps is making admissions selections in part based on the likelihood of career (as opposed to academic) success. There is a degree of "would I like to have a beer with this person" in the application process which is absent from traditional academic institutions like 'Old State U.'
One of the operating models of bootcamps is as a recruiter for tech companies. In addition to tuition from students, the bootcamp receives a fee from employers when graduates are hired. This provides incentives bootcamps to encourage students to take jobs as apprentices. And whether a student has the financial resources to take on an apprentice role can also factor into admission selection.
