I bought the book “Heard on The Street: Quantitative Questions from Wall Street Job Interviews” by Timothy Falcon Crack several years ago when I was looking for a job and felt that working in finance was a possibility. Despite having bought it simply to prepare for employment interviews, I actually enjoyed the math problems in the book.
The book has problems in logic, probability, statistics and finance, as well as a very useful chapter of general interview questions. If you’re interested in buying this book, I should mention that some questions require calculus and knowledge of financial terms.
I love the author’s taste in problems, and here are some sample questions from the book.
Question 2.7: How many degrees (if any) are there in the angle between the hour and minute hands of a clock when the time is a quarter past three?
Question 5.1.14: Welcome to your interview. Sit in this chair. Excuse me while I tie your arms and legs to the chair. Thank you. Now we are going to play “Russian roulette.” I have a revolver with six empty chambers. Watch me as I load the weapon with two contiguous rounds (i.e., two bullets side-by-side in the cylindrical barrel). Watch me as I spin the barrel. I am putting the gun against your head. Close your eyes while I pull the trigger. This is your lucky day: you are still alive! Our game differs from regular Russian roulette because I am not going to add any bullets to the barrel before we continue, and I am not going to give you the gun.
My question for you: I am going to shoot at you once more before we talk about your résumé. Do you want me to spin the barrel once more, or should I just shoot?
Question 6.1.16: Tell me something you tried but ended up quitting on.
I can tell you what I would have answered to the last question: I tried smoking, but ended up quitting.
