I applied online. The process took 2 weeks. I interviewed at Botify (Paris) in Oct 2017
Interview
Phone screen, some code to write at home and a technical design interview on site.
The code to write at home was a small algorithm implementation, it took me less than 2 hours.
The design interview was very interesting, it was more a discussion rather than an interview, and was very surprised to learn lots of new things and tricks which is often not the case when doing an interview.
