Premier appel avec un talent acquisition. L'appel est agréable, on me parle d'un test technique envoyé dans la journée. Une semaine après rien a part un test de maths sans explication supplémentaire. Je le fais, on ne m'a plus jamais répondu malgré mes relances. Très impoli.

Technical Case
First phone call to discuss my motivations for the position. Then an on-site interview with a case study to test my ability to understand and identify the various factors influencing carpooling prices. I assume there would be more on-site interviews after that, but I didn't go any further.
Confirmed questions1 question
- Case study on various carpooling elements. It was detrimental if you had never used the site or carpooling (e.g., number of km between 2 cities, different parameters affecting carpooling price).
