hello everyone. for those of you who care enough about my life to continue reading, this entry will be a compilation of the questions i received today at superday. this was for blackrock financial modeling group.

--

technical questions:

1)

use C++ to program an entire program (that should compile) that does the following:

takes 4 inputs (number of quarters, number of dimes, number of nickels, number of pennies) and return the total amount of change you have.

2)

what is deconstructing and why is it necessary?

3)

what is a resource like memory that when is allocated, must be de allocated?

4)

you have two random variables X and Y. both of their variances is 1. what is the variance of X + Y?

if given that the covariance between X and Y is 1, what is variance of X + Y?

5)

you have a rock in a boat sitting in a pool. you remove the rock and put it into the bottom of the pool. the rock's density is greater than water. does the level of water increase, decrease, or stay the same?

6)

integrate:

a)

integral of  1/x * dx

b)

integral of lnx  * dx

7)

integrate:

a)

integral from negative infinity to infinity: x* e^ (-x^2/2) * dx

b)

integral from negative infinity to infinity: e^(-x^2/2) * dx

find two more methods of integrating both integrals.

8)

what is duration of 10 year zero coupon bond?

what is duration of portfolio of 70% 10 year zero coupon bond and 30% 20 year zero coupon bond?

9)

10)

write a recursive function.

11)

write a program that does the following (in compilable c++ code):

the input is a number. return true if the number has any number of consecutive numbers that add up to it (for example 5 would return true because 2+3, consecutive numbers, is 5. 4 would return false).

12)

write a program that calculates factorial with input n.

13)

what is dangling pointer?

14)

how to find the size of an 'int'? (integer object)

15)

write a program (pseudocode, thank GOD) that does the following:

take a string and reverses it (thanks mike gao)

16)

17)

what are chances that of 1000 flipped coins, 600 of them are heads?

interviewing skills 101

interviewing preparation is a key element of success in leaving your best impression upon the firm and the interviewer. for any given question, an appropriate response should be prepared and practiced so your tone and flow are genuine. since interviewers go through many candidates at a time, try to make your response unique: make your answer reflect your own personality and character and use stories and concrete examples that are true.

here are some common interview questions:


tell me about yourself.

my name is andy jiang, i'm 5'8'', 140lbs, blood type O, shoe size 10 american. i love runny egg yolk, hot sauce, and pulpy orange juice.


have you done any trading previously?

yes, i have bought and redistributed marijuana, adderall, and shrooms, and am fairly familiar with those markets in the new england area. i began my career in the drug market by specializing in high end marijuana markets doing individual sales to clients. as i became more familiar with the marijuana market, i moved towards sales between businesses, and ultimately began trading weight and focused on increasing trade volume. i focused on arbitrage opportunities and compared prices of different strains in different locations to determine any openings in the market. at the same time, i was constantly looking for investors and speculators who were interested in participating in the market. marijuana and adderall are highly liquid market (except during the end of college semesters for weed and during exams for adderall), whereas shrooms is highly illiquid market.


what makes you the best candidate for this position?

i was born with a keyboard in my hands. since the moment i was able to process sight, i was using microsoft excel. i have logged over 5000 hours ONLY doing control-c, control-v (my total logged hours for all excel functions exceed 8 years). i have wet dreams about spreadsheets and the little microsoft paper clip helper guy, only to wake up at the crack of dawn to pull open excel and start copying and pasting. there is no task imaginable that is more intellectually stimulating than repeat control c, control v. when i do not have the pleasure of sitting in front of a computer, i have a fake keyboard that i practice excel hot keys with, to keep my mind sharp.


remember to be honest and genuine while answering each question. practice in front of a mirror to help solidify your physical impression.


more to come later..

andy
