Seriously the actions of all these big companies shows they don’t really give a shit about retaining top talent. Unfortunately, for big name companies, they’ll always have an inflow of talented new grads who are willing to give up their dignity to get their name on their resumes, and it’s cheaper (in the short term, which is all shareholders care about) to churn and burn them then to invest in long term talent
