I applied through a recruiter. The process took 3 months. I interviewed at Vanguard (Malvern, PA) in Feb 2010
Interview
Vanguard essentially wants a intern who fits with the rest of the employers within the company. Therefore the interview process consists of mostly behavioral questions ranging from easy to extremely difficult. Be prepare to come out with scenarios about what you have accomplished using the STAR method. If you are going to the company for interview, dress conservatively because that is the culture there. There will be a phone interview to screen applicants then if they like you enough they will invite you for interview at their headquarter which consists of 2 one on one interviews and a presentation.
Interview questions [1]
Question 1
Tell me about a time you had difficulty leading a group and how did you go about resolving the situation
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.
I applied through university. I interviewed at Vanguard
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.
