I applied through a recruiter. The process took 3 days. I interviewed at Criteo (Paris) in Nov 2015
Interview
A recruiter contacted me via LinkedIn, then called me on the phone to take basic information. Then an engineer interviewed me on Skype. One week later I passed half a day on site. The following day I got an extremely positive feedback which made me think I am practically in. A week later I interviewed with 2 managers, we discussed my experience and the field I work in (which is TOTALLY different than online ads and which those managers never worked in). The following day the recruiter called me to say they will stop the process giving me a very strange reason: "you didn't explain well what you were doing in your current job" !!!
