I applied through university. The process took 4 weeks. I interviewed at Vanguard (Valley Forge, PA) in Nov 2008
Interview
Heavily behavioral focused, especially relative to other interviews in finance. One round of interviews on campus and one round on Vanguard's campus in Valley Forge, PA. Vanguard will pay for your travel expenses, including flight, hotel and car service. Interviewers inquired into other opportunities pursuing as well as thoughts on living in Philadelphia. Most questions focused on examples from college and/or other work experience. Interviewers consisted of both investment professionals and HR professionals. For the most part, everyone was very approachable and thoughtful.
Interview questions [1]
Question 1
Tell me about a time you witnessed something unethicial and what you did about it.
Simple process. Went through Drexel with the co-op program. One phone call and then one in person interview with direct manager and then a week later received the offer. Pretty straight forward. Great company and good people.
The process spanned 3 rounds. First was resume and technical questions. Second was coding DSA and regressions. Third was research questions. Overall people were very nice, the process went smooth and fairly quickly.

Interview
Very chill, just behavior questions. Asked me about my communication style, what courses/knowledge of data science/machine learning that I had. Why I wanted to work in finance. It was very enjoyable/conversational.
