Introducing the dreamie:

I am graduating soon and I started interviewing with the Big I banks for a Quant Strategist position. I had close to 8 phone interviews over the past 3 weeks all with Russian Theoretical physicists. Being a mere master’s student, you can imagine how intimidating it was. Anyways,  I thought it would be fun to share some of the insanity I’ve seen:

One liners:

Question 1: How many digits does 2^71 has? How confident you are in your answer?

Question 2: How many primes are there less than 1000? Provide a confidence interval.

More involved games:

Question 3:  A frog sits on an infinite line. It can jump in steps of 2 to the right and in steps of 1 to the left ( both with probability of 1/2).  What is the probability that it returns its initial position.

Question 4:  You have a standard deck of cards with 26 reds and 26 blacks placed on a table face down.  You and a player take  turns flipping the cards , one by one, if it’s red you win 1 dollar if black you loose 1 dollar. What is the optimal strategy to play this game? i.e When should you stop.

I have plently more if folks are interested.

Surprisingly , I managed to do well . I’ll find out in 2 weeks if I got the job
