Overall took just over a month - applied online then was offered a phone interview 2 weeks later. During the interview I was asked about my employment background, reasons for applying to Vanguard and basic market knowledge - what is the difference between a mutual fund and an index fund? Interviewer also asked if there was anything relevant in the news which may affect the financial markets. I was scheduled to interview in person 4 days later at the Scottsdale campus - interview process took 3-4 hours. Begins with a one hour presentation about the company where any questions may be asked. After the presentation the interview is split into 2 separate interviews. 1 hour is spent with a team member discussing your CV and being asked behavioural questions. The next hour is spent with a separate team member where you must deal with two scenarios - one is paper based and the next is a role play - both fairly straightforward - important to remain customer focused. Then an assessment is conducted - this assessment is not seen by the interviewers is only used upon employment to create a learning plan for passing the series exams. Overall the process was fairly straightforward - as long as you are genuinely interested, knowledgeable and keep up to date with market news you should be fine.
