The process took 2 weeks. I interviewed at data.ai (Sanlitun) in May 2017

Several rounds of interviews: codility test, high manager interview, department manager interview, VP interview, and case study.
In general, all the interviews were very nice and professional, and the company treated the position very seriously. Hire manager is super smart and deep in technology.
