Applied through my college, first interview was on campus group, a little harsh. Next round was pretty easy business/pricing decisions over skype. Then I got flown out to BK headquarters in Miami for the super-day. There were about 12 of us, we played a business game and got a tour, then around noon they cut half the people. I made the cut to the final panel interview with 5 others where they grilled you on your resume/questions that make you think on your feet. I didn't get an offer but the company culture seemed kind of toxic--they promote very quickly but that also means they have very high turnover, so nbd.
