I applied through other source. The process took 2 weeks. I interviewed at UBS in Nov 2011
Interview
Mostly behavioral: WHY IBD? what do you know about IBD? WHY UBS? Go through your resume
Technical: how to valuate a company? the relationship between rD,rE and WACC
a director from Hong kong office interviewed me, he's very nice and gave you a hint when your answer is not correct
