Pros
Vanguard does offer some great benefits, i.e. mental health, tuition reimbursement, etc (if you have the time to fill out all the paperwork and jump through the hoops)
Cons
Vanguard is owned by the investors, which is a really cool concept. However, it means they are an "at-cost" company. If they can get recent grads to do terrible work for little pay, they're going to pay recent grads next to nothing to do terrible work. As a manager I was doing the job of 3 people with new responsibilities and expectations being added to my plate all the time. I was given a dollar amount each year that I was required to find savings for. I.E. find inefficiencies, fix them, and make sure there was a large monetary benefit. All while coaching my team of inexperienced "investment professionals" that they'd hired the day before. These individuals came with no experience which would normally not be a problem, but they were allowed to speak with clients before they even knew how to navigate our own website or do a simple transaction; let alone submit a timesheet or navigate the wiles of corporate America. All in all, I was NOT compensated accordingly. I was doing the job of both a people manager and a project manager but not making nearly enough in my base salary. I was never offered a bonus when the innefficiencies I found were fixed and the savings I actualized improved the company. I watched my crew suffer day in and day out while they took back-to-back phone calls without being able to offer them any hope of a break. I was expected to coach them to be better at their jobs, find new roles, and make sure they were happy and healthy but not allowed to take them off the phones for more than an hour a month. At the sacrifice of my mental and physical health I stayed for too many years trying to make things work.
