Vantaggi
The company's mission of serving military personnel and their families is admirable and carried out very well by the senior leadership team. The company really cares about their employees and provides great benefits to maintain a low employee turnover. Annual Bonus, Christmas Bonus, far more paid vacation days than almost any Fortune 500 company; 8% 401K match, gyms at work, events for employees...the list goes on and on. Providing you work in a support role (IT, Compliance, Mgmt) the compensation is pretty darn good. Also, they are becoming stronger advocates for working from home and believe in work/life balance.
Svantaggi
The amazing benefits and perks is a double edge sword as management can be very tenured at USAA and thus might not have outside experience in their particular industry/field to bring new/fresh ideas to their area; i.e. "We have always done it this way, so why change things". It can be difficult to instill change in a department if your not already a manager or at a senior level because mgmt might not listen to you. .
