There were about 3 to 4 rounds of interviews meeting with several people above and at the same level to your applied position.
Initially you communicate with a recruiter through email to coordinate a telephone interview. The phone interview starts with an extensive overview on how Ubisoft is structured then proceeds to your typical Q&A. Please make note the overview is a long-winded speech.
If invited back you meet with HR and everyone else . It's mostly conversational mixed with Q&A as opposed to situational or behavorial. The people seemed nice, easy to speak with, and has worked there for a very long time. Average 5+ years.
The crowd isn't diverse at all and it's a tight knitted group. You guys can do the math on this as some might approve but others might not.
It'll be interesting to see the stats on diversity: gender, ethnicity, openly LGBT, and also income disparity at this company. From my memory, there was only one person of color in the office.
