I’ve found Culture Queries to be a good resource for this. Helped me avoid questions that led to boilerplate answers (“do you have work/life balance?” -> “How responsive are people to emails/Slack over the weekends and after 6pm?”).
The main point in this article seems to be that Silicon Valley companies like Uber and Theranos skirt responsibility for their actions when compared to other non-SV companies who have undergone serious disciplinary action (such as United, Wells Fargo, Fox, Volkswagon).
But the author is comparing public and private companies and stating that the main difference between the two is their zip code. This feels like apples to oranges.
I'd rather see a comparison of how ethical issues are handled between SV and non-SV privately-held companies.
