The brain teasers were not hard - just required a little bit of thinking and keeping cool under pressure. They want to see how you approach and analyze a problem, as well as how you evaluate your answer choice and think on your feet. At the on campus interview the question was "estimate how many golfballs could fit inside a school bus". On-site one was "there are 4 people that need to get off an island. One takes 1 minute to cross the bridge, one takes 2 minutes, one takes 7 minutes, and one takes 9 minutes. There is one flashlight and it must be used when crossing the bridge. What is the fastest way to get everyone across?" Neither required super out-of-the box thinking, and if I got stuck they offered me a hint which led me to the answer. Look up some practice brain teasers online beforehand and relax and have fun when answering them!
