I applied online. The process took 4 weeks. I interviewed at AlphaSights (Seoul) in Oct 2015
Interview
First, got an e-mail for Cangrade test and Video Assessment. Then, 2 weeks later I got an international call, directly from HK to inform an interview schedule. So you'd better take unknown number callings. Anyway, then, an interview is processed with manager at the liaison office in Seoul. 1 hour as 1:1.
