I think it's more likely than not that you're aware of this, but there's a large selection bias in collecting respondents from DataTau. Those who did not get a job in data science following DS bootcamp are far less likely to be browsing DataTau than those who did.
Yeah, among other biases. "Voluntary response data are useless." I've also tried posting it on /r/datascience but it appears to have not showed up in the sub, maybe because my Reddit account is too new. Do you have suggestions for other DS communities where I could solicit responses?
Hacker News maybe? Not exactly specific to data scientists, but I believe there's a significant number of data scientists lurking around. Same biases, but it seems you're aware of those.
