^ Defense sector AND military. Dual income/benefits. The point is investment banking makes you put all your eggs in one basket if you will. When you work 80+ hours a week, you have zero time for anything else. Your career will largely be dictated by your employer because there’s no time left to work a hedge against the up and out culture of investment banking.
I’m would never advocate a relationship where you slave away for an employer and largely let them determine the progression of your career.
