Received a quick call about the first step what was a case study, barely other information or questions in that call. Received the case study and sent it - and never heard anything back despite follow up.

After sending my application, I've been rapidly contacted by the Product Manager for a first quick interview (~ 15min) on Zoom. Then, he proposed me to fix a second interview with 2 other design team's members. After those 2 interviews, I had to realize a small graphic exercice in 2 days. In the end, they finally decided to move forward with my candidacy, I had one last 15 min interview with the Chief of Staff and they made me an offer. The process took ~ 2 weeks.
