IGT Game Mathematician interview questions

I first had a phone screen with the recruiter followed by a one hour phone call with many members of the team. I was then invited to interviews on-site. The interviews were very behavioral oriented and they asked almost no technical questions, although some questions were asked about my casino gaming background as well as other questions on my background. For the most part the questions were straightforward and the interviewers were friendly, but I had one panel of interviewers who were outside of the team I was applying for and they made me feel kind of uncomfortable. They asked me mostly behavioral and a couple of trick questions; some of the interviewers even made sarcastic and negative remarks to me. This one interview seemed like more of an interrogation than an interview to be honest. But besides this it was a okay experience overall.
