The big tech companies are VERY standardized in their compensation for new grads. I guarantee you that at the one I know in the most detail, the base salary for a new grad is a bit over $100k. Add bonus and stock, and it's pretty easy to get to around 150k within a year or two. Not base, but total cash compensation. This is certainly not AVERAGE, but those companies hire thousands of engineers, so it's not exactly "unicorn" status either. This is not an estimate, or extrapolated from a couple of data points - this is actual knowledge of the compensation structure I'm speaking from.
$111,885 average [1]
$110,554 average [2]
$103,000 average [3]
I know this is HN, where everyone makes $150K and has $1M in savings and a supermodel girlfriend, but in the real world I think things are a little different.
