1st round: I'm going to roll two dice, we both have to pick a number and whoever's number is closest to the dice roll wins. Do you want to pick first or second? (there were a bunch more, but I can't remember them) 2nd round: You have the numbers between 1 and 30. What is the largest sum you can make by picking out numbers but only using each prime factor once. (eg. if you pick 6, you can't pick any other number with a factor of 2 or 3). (again, there were more, but I can't remember them) 3rd round: Explain your choice of major for this position? Why did you apply? Why are you interested in an internship at Jane Street? You have a safe with six digits and a light. You can input a code, if you have between 0 and 3 of the 6 digits correct, the light will turn red. If you have between 4 and 5 of the 6 digits correct, it will turn yellow and if you have all 6 digits correct, it will open. There is $10, 000 inside the safe, you can guess the code as many times as you want, but need to pay each time you guess, how much would you be willing to pay for each guess?

1) If you have 4 fair coins and each time you get heads, you get $1, what is your expected profit? 2) Same as above, but now you have a magic wand to flip 2 of the same type (i.e. flip two heads or two tails) as many times as you want. What is your expected profit now? 3) Same as above, but now imagine 100 coins and you still have the magic wand to flip 2 of the same face at a time as many times as you want. What is your expected profit?
