Actual Wall Street (trader) Interview questions

Here's two brainteasers for you:

    1. (Don't read this one you are easily offended):

    How can three men and one woman have mutually safe heterosexual intercourse with just two condoms ? Assume that no condom can break or leak, and that you cannot wash a used one.

2. A rock is dropped from the top of the Empire State Bldg. At what speed does it hit the ground, and how long does it take it to get there ?

The answers will follow -at the end of the day-.

enn_doubleu1. Two of the men wear a condom apiece, while having sex with the woman. The other man jacks off watching from the corner of the room.

Like that.

Please, first one is from heard on the street, the second one is basic physics.

(but yeah this question has been asked before and I won't spoil it)

  1. A rock is dropped from the top of the Empire State Bldg. At what speed does it hit the ground, and how long does it take it to get there ?

Troll Answer: It hits the ground at a speed of zero. It's moving before impact and after impact, however the moment the rock impacts the ground the ground pushes back with equal force. It takes approximately no time to get there (there being the speed on impact) as the rock starts at a speed of zero.

Real Answer: Probably having to do with the terminal velocity of the rock and how long it takes to reach that. Wouldn't you need to know the weight of the rock? Me no don't do good science stuff.

 

Given the possibility the bitch has oral herpes, I can think of at least 4 other orifices that can get the job done.

All you need is a rubber hose, and a large kimono dragon.

 
ScorpionI got the solution to #1 while talking with a friend over dinner...dunno what that means for me >.>

First question I had was how broadly we were defining heterosexual sex here, but I figured that got way more behavioral than the interviewer would be looking for...so assuming each man just has penile-vaginal intercourse with the woman, here's the solution, assuming no leakage and Latex erosion, and assuming condoms are handled gingerly to prevent hand-to-hand infection somehow (basically all of the crazy scenarios are out):

Guy #1: Doublebags it with two condoms. Finishes. Takes off the outside condom and passes it to Guy #2. Guy #2: The outside is potentially contaminated with the woman's STD's, but the inside is completely safe. Uses only the outside one, same orientation. Finishes. Passes it to Guy #3. Guy #3: The outside and inside of the outside condom is infected, potentially. The only solution left is to take Guy #1's inside condom, turn it inside out, and thus place this inside condom inside of the outside one, and finishes. All sides of the condoms are now infected, but all participants are satiated.

  1. Yes, that's the answer.

  2. Was answered by ytnifny

If you want to detail, you can say: Ignoring air resistance,

We need to know how high Empire State is. From memory, about 100 floors/ each fl. about 4 meters high- so that's 400 meters high.

Using the simple equation of motion, v^2 = u^2 + 2gD, where v=final velocity, u=initial (zero), D = distance = 400 m, g (gravity)=9.8 m/s^2 ~ approx 10 m/s^2

v^2= 210400 = 8000 m^2/s^2, v= approx. 90 m/s

v= u + g*t, so t ~ 9 s.
