Explain what you mean by 2,3,4x more please. You can look at levels.fyi and if you are in a big tech see what the big companies are paying, that sets the market. In my experience the amounts of sometimes shockingly high, but eliminate a few crazy outliers and I see accurate rates. I'm a 20 year experienced principal engineer, and I see rates that match what I get.
So what would 2,3,4x mean. Do you mean that much over your current salary, or over the 'market rate'. If someone paid me 2 or 3x my market rate as a principal backend infrastructure engineer, I would take it, but a year ago when I was interviewing, the offers from the big guys were not that different.
