Interviewing at Criteo: Just do it!

Being interviewed for a job is always a stressful experience. Trust me, even for a recruiter, it is tough!

It takes courage to voluntarily go out there to be challenged and evaluated. As an R&D Recruiter, I often hear candidates stating : “the process is too long, I am busy”, “I am not good enough to succeed  at Criteo’s technical interviews”, “I have been working for 10 years for the same company and I would have to prepare hard, etc…

Well, well, well… It might not be the right time for you to interview but I can tell you a few things

Criteo at RECSYS 2016

Criteo was in full force at the 2016 RECSYS edition in Boston. With 10 people from our Paris office and 1 from Palo Alto, it was the place to be for the Reco team. The researchers were also in the spotlight with 2 Criteo papers published, (Thanks Elena, Flavian & Yu-Chin!)

We also had members of our recruitment team present to raise awareness for the Criteo employer brand, meet curious minds with tons of questions about working at Criteo.

For the opening keynote Claudia Perlich (Dstillery), a widely acclaimed expert on big data & machine learning, presented her latest, state of the art, recommender system at Dstillery. It felt good knowing that it was a scaled down version of our own in house system. We do have the best technology (woot! woot!) They are using logit with hashing trick + a modified collaborative filtering.

The current trending topic of the conference was clearly embeddings, everyone is trying embeddings and we expect them to be a big thing in the coming years. Hopefully thanks to the work of Flavian & Elena, Criteo is still ahead of the curve, while people were discussing the possibilities of embeddings at the conference, we were already ABTesting them.
