The process took 8 weeks. I interviewed at Expedia Group (Paris)
Interview
Aucun professionnalisme de la part des RH !
- un entretien avec le team manager en vidéo avec des questions plutôt techniques
- coding assessment (3 exos)
Ex1: somme de 1 jusqu'à n sans les multiples de 5 et 7
Ex2: combien de jours un voyageur doit passer dans une ville pour qu'il puisse faire toutes ses activités, étant donné une liste des activités (heure début et heure fin) résultat le nombre de jours
Ex3: Traitement de texte, analyse fréquentielle des documents sans utiliser des librairies pré-existentes
Interview questions [1]
Question 1
- "présentez-vous"
- "pourquoi avez-vous choisi Expedia group?"
- 10 (ou 9) questions techniques: apprentissage supervisé, apprentissage non supervisé, cross validation, sur-apprentissage, collinéarité, métriques d'évaluation des modèles, comment vérifier que deux échantillons ont les mêmes statistiques...
I applied online. The process took 2 months. I interviewed at Expedia Group (Genf) in Aug 2021
Interview
The interview process included 6 steps:
- 1 HR screening
- 2 technical interviews (the first one was focused on the past experience and another one was checking my knowledge of ML concepts)
- 1 behavioral interview
- 1 coding challenge
- 1 'job simulation' interview with the hiring manager.
Overall, the interview process took more than 2 months.
Positive points:
- the team members are highly professional and kind
- the workflows inside the group seem to be well organized
Negative points:
- a very long interview process
- surprisingly, no questions/no interest about my past experience from the hiring manager
- no feedback in the end, except a very formal 'you did not pass the job simulation part'. I contacted the HR that was in contact with me to get more details (which would be helpful to know to identify the weak points to work on) but, unsurprisingly, never heard back from her.

I applied online. The process took 4 weeks. I interviewed at Expedia Group (London, England) in Aug 2019
Interview
It starts with a quick call with the Hiring Manager. After that, you are asked to work on a challenge (Kaggle style). You are allowed a few days. The final stage consists in 3 parts (presentation of your challenge, technical interview and competency based interview).
