Applied online and was immediately sent a link to complete a virtual job tryout. A recruiter emailed me a few weeks later to set up phone interview. The phone interview was about 45 minutes and mostly just went over the role and the company to see if it was a good fit. I was asked two behaviorial based questions. At the end of the phone interview the recruiter scheduled me for a zoom interview with the hiring manager. The recruiter prepped me extensively for this interview. She sent me a long email with every topic and detail I needed to know about the company. The recruiter called me again a few days before my final interview to give last minute advice and answer any questions. The final interview was 2 hours. The first hour was a class where we learned about the company and its benefits. The second hour was one on one with the hiring manager. It was more like talking to a friend. Honestly though I was not asked anything that I had prepared. I was asked 5 behavioral questions. I did my zoom interview on a Friday and was offered the job on the following Monday. The whole process took about a month. Vanguard hires very far in advance though so I suggest applying earlier than you're hoping to start.
