I applied online. The process took 4 weeks. I interviewed at BlaBlaCar (Paris) in Dec 2015
Interview
The process took about one month, which included various phone and onsite interviews.
It all started with an online application. A few days later I was contacted by an HR manager to set up an initial interview.
Immediately afterwards I was asked to take a generic coding test, which was done online.
Then after a couple more interviews with other developers, you had to do another coding test onsite, this time it was android specific.
