The atmosphere was transparent and respectful throughout.

Question 1
Challenges dealing with raster data from different data sources
I applied through an employee referral. I interviewed at adsquare (Paris) in Jun 2026
Interview
Processus complet, avec un premier entretien RH, un deuxième entretien fit avec l'équipe Sales, puis un cas pratique avec une restitution comme en agence.
Le tout hyper flexible, en visioconférence
Here's the updated translation:
The process was rather poor. To be honest, the meeting was scheduled the day before for the next day because the CEO was passing through the city.
On the day of the appointment, which was planned for 1 hour, he arrived 15 minutes late and told me he had to cut it short by 20 minutes, so 25 minutes instead of an hour.
We then exchanged a few thoughts on the market, with the idea of having a longer conversation at a later point.
Two days later, I received a rejection from HR, with no explanation. I asked why, and got complete radio silence.
This is about as unprofessional as a recruitment experience can get, definitely something that needs to be reconsidered on their end.
