lol noone is paying $300k+ for fresh phds. $200-250k is more reasonable but even that is on the high side, most places will be around $150k-200k.300k is standard at two sigma
At elite hedge funds, they pay them $150K+ base and up to 100% bonus. I can 100% confirm this. Heck, they pay software developer interns at the rate of $150K per annum, but for 3 months.
