Curious what your estimate of a 50th and a 99th percentile developer salary is for a new grad? And do you mean a 50th percentile CMU grad, or a 50th percentile CMU grad developer, or just overall?
ASAIK, Goog/Uber/FB starting salaries are closer to 110k base with $40-50k RSUs vesting per year (refreshes each year), performance bonus 10-15% salary and sometimes a generous signing bonus.
