I applied in-person. The process took 4 weeks. I interviewed at Christie's (Hong Kong) in Aug 2017
Interview
Brief one on one with a dept. manager nearby. Very friendly, casual, low-key and informative. Spoke mostly about background, skills, experience, and possible opportunities within the company. Was told would be hear back from them in due course, which they kept to. Good experience all-round.
Interview questions [1]
Question 1
Nothing specific, just a general conversation on background and experiences.
