First a phone call with a hiring manager, then an analytical test on different digital marketing terms and metrics. They give you plenty of material to prepare for the test, can only really see it being difficult for someone not comfortable with numbers. After I passed the test I had Skype interviews with two of the sales directors. Pretty easy conversations just looking to get to know me on a personal level of sorts. After I passed those, they flew me out to Boston to do a presentation. The presentations is essentially just a pitch of the Criteo Value prop to a random company of your choice. They give you plenty of material to prepare with and the presentation is for 4 people at once who are listening and bouncing questions off you. Got the offer a few days later and I couldn't be more excited! Great people and excellent recruiting process.
