I applied online. The process took 3 months. I interviewed at Christie's (London, England) in Oct 2010
Interview
The first round assessment was writing about 4-5 questions about teamwork, leadership, experience etc.. The second was telephone interview. Then comes the one-day assessment. There are 3(or 4, can't remember) parts. A. Role play. You're the assistant and your boss is absent, try to talk with the client and get more details. B. Presentation. Introduce a painting to a private client. C Group discussion. Different location department colleagues allocate the painting resources.
Interview questions [1]
Question 1
Group discussion. As you need to make as much profit as you can for your department, but in the corporation strategy view, you also need to co-orporate with other colleagues. No perfect solution
