### Software Development Engineer at Microsoft was asked...

 What if I place a cap D on the amount of money you can earn (alternatively, you can flip the coin up to D times)? Now, what is the amount of \$ you are willing to pay to play this game?1 AnswerNow there is no condition between succesive flips; each filp has 50% chances to add one dolar, so in the end a good chance would be to have D/2 dollars on the table. Start with 1 dollar and negociate up to D/2 (or a little bit more if D is small, but not too much if D is big!) Is is a condition that you have to win the last flip? then there is a 50% chance to take the money! This makes the game more interesting, but I don't think you have to change the limit to D/4 - is all about your taste...

 Mentally draw two lines from the endpoints of the diameter of a circle to any point on the circumference. Can you prove that the angle with vertex on the circumference will always be a right angle? How?1 AnswerWe can split the triangle in two by drawing a line from the centre of the circle to the point on the circumference our triangle touches. We know that each of the lines which is a radius of the circle (the green lines) are the same length. Therefore each of the two triangles is isosceles and has a pair of equal angles. But all of these angles together must add up to 180°, since they are the angles of the original big triangle. Therefore x + y + x + y = 180, in other words 2(x + y) = 180. And so x + y = 90. But x + y is the size of the angle we wanted to find.

 What experience to do you have working in a lab such as this one?1 AnswerI had no experience, but I mentioned that I had taken AP chemistry and AP biology with labs in high school and I was enrolled in general chemistry and biology at VCU, which provided basic lab skills and experience.

 A completely preposterous proposition trying to make a connection between my yacht racing equipment design experience about how the stresses in the mast of a sailboat are like a cantilever beam.1 AnswerMy description about how a mast is stayed and supported did not seem to please them; they apparently wanted a text book answer about the theory of the cantilever beam.
