The salaries for the FAANG companies are dramatically higher than even other large Silicon Valley companies. Over four years ago my first job after graduating with a MS in computer science was at an old-school Silicon Valley giant. My offer was $100,000, roughly $2,500 of stock that vested over 3 years (with a one-year cliff), and I negotiated a signing bonus that was a little less than $4,000. While the salary was about at par with what FAANG companies offered at the time to those with similar credentials, the rest of my compensation was a far cry from the offers I've heard of from the FAANG companies.
Given the large differences in compensation (which makes a big difference when trying to save for a house in this area), I wonder how older Silicon Valley giants are able to compete with FAANG companies? Startups can justify lower compensation since there is the possibility the startup would be very successful. I wonder for giants if the difference largely boils down to interviewing processes? I do know that getting into a FAANG company is difficult and requires many months of grinding LeetCode, whereas not all Silicon Valley companies have difficult interviews.
