I applied in-person. The process took 4 months. I interviewed at Ogilvy (Singapore) in May 2012
Interview
Series of one on one interviews. It was a "reverse process" - it started with high up discussions, then a series of discussions with more middle junior people. The top people were more focused on whether I could do the job and the lower down interviews were focused on whether I would fit in.
Interview questions [1]
Question 1
Why I felt I could do the job and what experience I would use.
