### Cracking the Finance Quant Interview

Hi all

Cracking the Finance Quant Interview: 51 Interview Questions and Solutions
https://www.amazon.com/dp/B08D4F8RJP

You can preview brainteasers with the "look inside" button on amazon. I will add a few questions here

Two sided corridor with rates:
Let Bt be a Brownian Motion and u and d two positive real numbers. We consider an option which pays 1 if Bt reaches u and remained greater then−d since inception
∃ t0 : Bt0=u ; ∀ t ∈ [0,t0] , Bt>−d
payment is made when the barrier is touched. Calculate the price of this option with rates r >0.

The binary hedge:
A trader suggests the following binary hedging strategy for a call option:
•sell a call option at strike K > S0
•buy the stock at K when St is increasing and crosses K
•sell the stock at K when St is decreasing and crosses K
What is wrong with this strategy?

End of times:
Let Xn be a sequence of positive random variables, such that E[Xn] =a and
limn→+∞Xn= 0 a.s
show that limn→+∞E|Xn−K|=a+K
Can this result be applied to a financial option?

Hey Bearish. I dont know if we could call them questions from the 90's, but I can guarantee you that we saw these questions being asked in the designated banks in the period 2019-2020.

How to compute $e^5$ with two decimal places?

viewtopic.php?f=26&t=79451

The interesting part is testing analytical thinking in addition to mind-numbing rote learning.

It sounds interesting, we might add it. We try to stick to real interview questions, was this question recently asked in a quant interview, and if yes which company?
