Ask anyone who’s at a major - handing your paycheck to a nanny, for three months, in order to get hired three months earlier, is a great deal.
The value at the end of your career (assuming you’re in your mid 30’s) is $45-50K per month.
If it pays off you’ll be 150-300 numbers more senior right away as well as 50-150 numbers more senior at the end of your career. As well as being $100-130K richer at the end.
