I applied online. The process took 4 weeks. I interviewed at Axiom Zen (Vancouver, BC) in Mar 2015
Interview
1) online coding test, can be difficult for coders who don't have algorithm background; need to use javascript or Go.
2) onsite technical interview, some algorithm implementation with whatever language you can use.
3) onsite technical interview, see how you cooperate with other engineers.
4) CEO phone interview, non-technical, get to know about past experience and such.
