Earlier quoted context omitted.
No, it is not a typical ratio. Bootcamps often have cohorts where there are 10 percent or even fewer women. For a bootcamp to have 40 percent ratio is impressive and unusual. Also - remarkable for all women to have a job at graduation. The bootcamp described sounds very unusual and the numbers are so very different from industry standard - that I encourage anyone reading to do their own research.
Which sites do you suggest for research?
I suggest talking to most recent grads of a program as things change all the time. For example, schools which previously had good placement may hugely expand number of cohorts - and not scale out job-finding resources or company partnerships.
