I applied through university. The process took 3 weeks. I interviewed at Vanguard in Mar 2011
Interview
The interview consisted of four 1:1 interviews around 30 minutes each. Very similar to a typical law office interview system.
The questions they asked weren't complicated, and all the itnerviewers were friendly.
Be prepared for small talk, especially when each interviewer walks you to the next interview.
The process took 1 day. I interviewed at Vanguard in Oct 2009
Interview
4 interviews, each lasting about a hour, with several members of the legal team. there were several presentations about the benefits of working at vanguard. there was also a catered luncheon.
