blackcock day of reckoning

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)
in fixed income, what is convexity?

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)
what is mortgage back security?

17)
what are chances that of 1000 flipped coins, 600 of them are heads?

18)
what does US government have influence over the mortgage backed securities? and for blackrock's clients?

--

other questions

1)
why family guy over simpsons and king of the hill?

2)
capital markets or computer science?
(i had the fudge this answer, of course.)

michael lewis weighs in

i came across this op ed piece by our beloved michael lewis (author of 'liar's poker') and it talks about wall street careers and our dreams. since i know a lot of people struggling with this, in times of recruiting and financial crisis, i highly suggest everyone to take a look. the last paragraph is gold and for people who don't know what they are doing and doing it because nyu stern tells them to then take his advice.

A Wall Street Job Can’t Match a Calling in Life: Michael Lewis


Commentary by Michael Lewis

Dec. 10 (Bloomberg) -- Recently I received a letter from a young employee of a well-known financial firm, who asked that I not mention his full name, his employer or anything else that might give him away. Though a bit short on self-pity and self- dramatization, this letter was otherwise a fine example of a sort I’ve received often these past few months.

“I am writing you for advice,” Anthony (let us call him) began. “I graduated in May of 2008 and since July have spent my time entangled in the culture of (his well-known New York bank). I’m thinking about leaving. My dad labored his whole life so I could have the opportunity to do something like this, so leaving isn’t exactly what I want to do. I know if I stay here I could work unbelievably hard and move through the ranks, or maybe move firms… (but) I guess I’m starting to question the whole securities industry.”

The young man went on to concede that what attracted him to Wall Street was the chance to get rich quickly, and the excitement -- but that both of these things now seem gone forever.

“So I have this plan to go to Hollywood,” he wrote, but then instantly undermined himself. “I feel confused, a little stupid, but yet somewhat confident. I mean, I read your book, I figured out how to get to Wall Street from a non-Ivy League school, and I got here. The only question now is, if I leave, where do I go?”

Let me try to help sort it out:

Dear Anthony, On several occasions I have taken my own advice and it has almost killed me, and so I’m a tad uneasy about offering it up to you. But if you promise not to take it any more seriously than I do, I’ll answer you as best I can.

Let’s start by putting your problem into perspective: You still have a job. You work at one of the world’s biggest banks. It’s true: The thrill and money is rapidly being drained from such places. Your big bank, like all the other big banks, seems to be in the process of being nationalized -- thus the longer you stay the more you may find yourself in something resembling a government job. But that’s not all bad: Government jobs are secure. You are also young, in your early 20s, and without a family to support. That is, unlike the vast majority of the people on and off Wall Street, you have the luxury to wallow in your misfortune. Now let’s wallow. We’re at the beginning of a recalibration of the role of finance in global economic life. The excitement and the money that attracted you to Wall Street will probably not return for a long time. If these really are the only reasons you became a financier you probably should find something else to do with your life.

Hollywood Lurch

But before you go lurching into Hollywood let us make sure you aren’t simply repeating the mistake you made by lurching onto Wall Street. That is, let us focus less on your immediate condition -- safely employed but disillusioned -- to the habits and beliefs that led you into it. You were never exactly wrong. If you’d been born 10 years earlier and behaved exactly as you have done, your career might well have made you as rich and seemingly successful as you imagined your father wanted you to be. You simply came to Wall Street too late, and are in the strange position of a man who won the lottery on the first day there was nothing in the pot. The mistake you made, in your view, is to have played the lottery on the wrong day. The mistake you made, in mine, was to have played the lottery at all. There’s a question you might ask yourself: Am I looking for a job, or a calling? On the one hand the importance you attach to your career suggests a desire for a calling; on the other, your instinct to abandon your chosen career the moment it ceases to offer an easy path to fame and fortune, suggests that what you’re really in the market for is a job.

Job vs. Calling

The distinction is artificial but worth drawing. A job will never satisfy you all by itself, but it will afford you security and the chance to pursue an exciting and fulfilling life outside of your work. A calling is an activity you find so compelling that you wind up organizing your entire self around it -- often to the detriment of your life outside of it. There’s no shame in either. Each has costs and benefits. There is no reason to make a fetish of your career. There are activities other than work in which to find meaning and pleasure and even a sense of self-importance -- you just need to learn how to look. Reading between the lines of your letter I sense that some of your anxiety is caused by your desire for the benefits of each -- job and calling -- without the costs. Perhaps that is what led you to Wall Street in the first place, and why your mind now turns to Hollywood.

Doing Well

What Wall Street did so well, for so long, was to give people jobs that they could pass off to themselves as well as others as callings. Such was their exalted social and financial status: Wall Street jobs made people feel special without actually having to be special. You never really had to explain why you were doing it -- even if you should have. But really, the same rule that applies to properly functioning financial markets applies to other markets: There’s a direct relationship between risk and reward. A fantastically rewarding career usually requires you to take fantastic risks. To get your seat at the table on Wall Street you may have passed through a fine filter, but you took no real risk. You were just being paid, briefly, as if you had. So which is it: job or calling? You can answer the question directly, or allow time to answer it for you. Either way, I think you’d be happier if you stopped thinking of what the world had to offer you, and started thinking a bit more about what you had to offer the world. Real excitement isn’t just in whatever you happen to be doing, but in what you bring to it.

In the end, you have to look for it not on the outside, but on the inside. In my experience, if you find it, the other stuff will take care of itself.

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
