"Estimate the number of flat tires each day in the united states." Both the phone interviewer and Skype interviewers were aggressive and at times rude. Questions were often pedantic and didn't pertain to my research.

The brain teasers were fairly straightforward. I can only remember a few. 1) Estimate the circumference of the earth 2) How tall would you be if your atoms were the size of tennis balls? 3) How old are my children if their ages add up to 'x' and the difference between them is 'y' 4) If I had two sand-timers of 4 minutes and 7 minutes, how could I accurately measure 9 minutes?
