I applied online. The process took 3 weeks. I interviewed at Datatonic (London, England) in June 2018
Interview
The interview process started with a phone interview and then an on-site interview with 4 different interview rounds (Programming and ML, Data Science, General, Data Science Case Study as a group). The interviewers were all really nice and interested in one's work.
