Online resume drop followed by a phone interview. The phone interview was primarily behavioral, but be be ready to also convincingly answer "why Vanguard" and "why financial services." A few days later I was invited down to an in-person interview in Charlotte. I met many other applicants, and then HR gave us a presentation about the company and the role. Then we each went into a separate room with an interviewer who also asked many behavioral questions and gave us time to ask them our questions concerning the role/company. Both phone and in-person interview strictly followed the STAR method; the interviewer emphasized this, and I was under the impression that they were filling in each step on a sheet. Surprisingly casual experience. Offer came the following week.
