I applied through a recruiter. The process took 2 weeks. I interviewed at Morningstar (Chicago, IL) in May 2011
Interview
There was an initial phone screening from HR, then a phone screening from the hiring manager, followerd by 2 days worth of interviews, lasting about 4 or 5 hours each day. I met with 2 people at a time for an hour. A senior C level executive normally is included for one of the hours, which is nice. You could easily find yourself across from Joe Mansueto himself, or the CTO / CFO.
Interview questions [1]
Question 1
Nothing memorable, overly difficult or unexpected.
