I applied online. The process took 1 week. I interviewed at UBS (Chicago, IL) in Jun 2014
Interview
Interviewed with HR over the phone first. An in-person interview with the hiring mgr and two more people followed shortly. One more on-site interview with the Managing Director. Another phone interview with the Executive Director overseas. Very friendly overall. Nothing technical, more of a "personality fit" process.
I applied through a recruiter. The process took 3 weeks. I interviewed at UBS (Weehawken, NJ) in Sep 2012
Interview
Very organized. I was able to do 5 interviews for my role in one day. This was quite welcome because I didn't have to take multiple days off for the interview process.
