Interview
I applied online through their website, which was fairly simple. They contacted me just a few days later looking to interview me, and from then on I exchanged short emails with an HR rep about good times for a phone interview.
Interview questions [2]
Question 1
They always warm you up with an "easy" question or two. In my second interview, the warm up wasn't so easy. They first asked, "If I roll two dice and tell you that at least 1 is a 6, what is the probability that both are 6s?"
Here is where the interview got difficult. The follow up question to the dice, "How much does the Earth weigh?" And then what is my 90% confidence interval.
4 rounds before superday. didnt make it to superday. first round was basic prob and stats questions. r2-4 is all hard game theory style questions. no behavioral at all.

3 online interviews before the final on-site one. The whole process is around a month. Mostly consists of probability questions. Poker chips are given in the final round to bet on certain decisions.

zuerst basic fragen zum einsteigen danach ziemlich schnell weiter mit theoretischen fragen. anfangend mit einer eher leichten frage und langsam drauf aufbauend mit neuen Bedingungen. insgesamt war es meiner meinung nach eine gute Erfahrung.
