## Objective: Get a Job as a Wall Street Quant

### Chapter 1: The Lure of a Quant Career

#### A Rewarding Career

• Monetary: a six-figure compensation (salary plus bonus, in US dollars) is almost a given, rougly $200k~$300k and even million bucks for some lucky and bright quants
• Psychological: aphrodisiac
• Spiritual: solve the challenges

If you cannot see the risk to every poential reward, you should not be working as a quant - in fact, you shouldn't be considering a financial career to begin with.

#### What is a Quant

Anyone who possesses strong quantitative skills and work with quantitative models is a quant. On Wall Street, a quant designs, constructs, implements, tests and presents quant models in the specific financial area he or she works in.

• Modeling process
• Model design: proprietary model / ad hoc model
• Model construction: transform the model from framework to implementable form
• Model implementation: convert the mathematical or statistical form to actual programming code
• Model testing: check the results and improve the implementation
• Model presentation: report to the upper management or clients; finalize the model into a product / service
• [Model selling or supporting]
• Quant types
• Financial engineer: build and implement the models, true research-oriented quant
• Quantitative analyst: more involved in model implementation than design and often possesses superior qualitative knowledge
• Quantitative developer: converts abstract modeling ideas into expertly written efficient programming code for implementation and production

#### A Typical Workday in a Quant's Life

• Typical daily schedule
• Different quants
• Quant traders: ultimately modeling people, toying with the models (refine, improve, calibrate, test)
• Financial engineers and quant analysts: work life like a Ph.D. student or newly minted, tenure-track assistant professor
• quant works hard, usually thirteen- to fourteen-hour workdays
• as you climb up the corporate ladder, you'll be working harder and harder

#### Is a Quant Job Right for You?

• Pros
• money
• perceived prestige
• doing work you may actually enjoy
• Cons
• boring work
• exhaustive literature search
• empirical implementation
• limited respect and recognition if working in middle or back office
• division of office
• front: the salespeople and the traders
• middle: research groups
• back: non-essential, non-revenue-generating units (eg. accounting, trade checking, IT support, etc.)
• stress
• difficult managers
• intense competition
• lack of certainty with respect to income or job satisfication

If you find the right job with the right group at the right firm at the right time, and if you work very hard, and if you are smart and creative, and if you are lucky, you might just win the Wall Street lottery, make seven figures a year and become the envy of the rest of us, yours truly included.

#### Non-Quant Finance Jobs

Quant people tend to be the straight shooters and lack the necessary political skills to climb to the top, both in power and in money.

• Corporate Finance (Investment Banking)
• Equity/Fixed Income Analysis
• Venture Capital and Private Equity

#### Where Quants Work

• Global integrated banks
• Investment banks
• Specialized financial service companies
• Mutual funds
• Hedge funds
• Venture capital and private equity funds

#### Designing an Overall Strategy for Getting a Quant Job

1. What kind of positions are you interested in?
2. List things you desire out of your job.
3. Now list your qualifications. Include your education and past quant-oriented jobs.
4. List anyone you know personally or have met in the past who works in Wall Street-type finance
5. Jot down places where you can find more contacts.
6. Finally, make a list of alternative options you'd take if you can't find the quant job you desire within a reasonable amount of time.

### Chapter 2: Brushing Up Your Resume

• your resume should possess the following characteristics
• use a clean layout
• stick to classic fonts
• list only the import items
• be concise but be concrete
• use action verbs
• one page or two pages?

Trust me, the resume is not the place where you try to be creative. Doing non-conventional things like putting your picture on the resume is still not acceptable.

#### Components of a Resume

• perfonal info
• objective
• quantitative and techniqual skills
• education
• experience
• publications, working papers or academic activities
• other relevant info
• references

#### Tailoring Your Resume to a Position

One popular route many job hunters follow is to have multiple versions of their resumes, each version tailored for a particular type of job.

#### The Single Most Critical Aspect of Your Resume

When you put down a skill on your resume, make sure you can back it up with concrete evidence.

### Chapter 3: Hunting for Openings

For many potential quants, the most difficult part of the job hunt process is probably finding where the job are.

#### When to Start Looking

The answer is simple: start looking as early as possible. Be an early bird.

• large firms and smaller firms
• opportunities
• recruiting season
• the annual ASSA (Alliance of Social Science Associations) meeting
• final year PhD student: thesis defense

The best time of the year to look for a quant job is in January, February or March. These three months are when the year-end bonuses are paid and a lot of people either switch jobs or quit the industry altogether, resulting in a lot of available openings - many of which need to be filled urgently (after all, somebody's got to do the work).

#### Where to Find Job Openings

First of all, forget about mass-appeal job websites like Monster or Hot Jobs.

• The annual ASSA (AEA or AFA) meeting
• Career or job fairs
• Niche websites that cater to quants
• JobsintheMoney.com
• Wilmott.com (with lots of general career advice)
• QuantFinanceJobs.com
• QUANTster.com
• www.quantcareer.com
• www.aeaweb.org/joe
• www.afajof.org/association/jobs.asp
• Professional societies for finance workers
• Bloomberg terminals
• Major daily newspapers as well as their websites
• Listservs and websites run by student organizations at your school or other schools
• Any contacts you can think of
• Cold calling
• the company's website
• finance professional society
• finance-oriented journals and trade magazines
• Journal of Finance
• Journal of Financial Studies
• Institutional Investor (www.institutionalinvestor.com or www.dailyii.com)
• Journal of Portfolio Management
• Journal of Wealth Management
• Euromoney
• Bloomberg Markets
• Wall Street Journal

• a person who identifies and approaches suitable candidates employed elsewhere to fill business positions
• the headhunter screens candidate for suitability for a position or a number of positions
• the headhunter may also approach candidates deemed suitable
• the headhunter is independent of the firms they recruit for
• legitimate headhunters are always paied by the hiring firms for their services
• if you fail to get an offer after two or three tries, you likely won't hear from the same headhunter again
• they have to bring the bread home, and they can only earn the bread if they succeed in placing candidates
• where to find them
• career fairs
• Analytic Recruiting (www.analyticrecruiting.com)
• Pathway Resourcing (www.pathwayresourcing.com)
• what you should say to them
• use phones instead of e-mails
• ask tips/improvement on the resume
• tell the truth about how much are you currently making
• expected pay for the new position

#### Leveraging Contacts for Job Search

The most attractive jobs are often taken before the public knows about them, and the jobs that are publicly posted are usually just okay.

• insider
• referral bonus policy
• suggestions
• collect contacts on Wall Street
• utilize the contacts

#### Connecting With Contacts at Seminars or Happy Hours

I tell myself that no matter what happens, 100 years from now everyone in the room will be dead.

By encouraging them to talk about themselves and thus making them feel good, you make them like you.

After you've made the connection, be sure to keep it warm.

### Chapter 4: Acing the Quant Interview

#### Types of Interviews

• In terms of medium
• phone interviews
• in-person interviews
• In terms of content
• informational interviews
• technical interviews
• case interviews
• combinationof the three

#### Scheduling and Interview

Schedule first the intervies for positions that you are the least interested in and place the important interviews (for the jobs that you really wat) in the middle of the pack.

The bottom line is, if you have any wiggle room at all at controlling an interview's time and day, use that flexibility to your greatest advantage.

#### Before Intervie Time

Any practive is better than no practice. (mock intervies)

• backgroud check
• compnay.department
• position
• interviewers

#### General Tips for Handling Interviews

Prepare, prepare, prepare.

• Groom and dress well for the in-person interview.
• Be sure to have had a good night's sleep and, in the morning, taken a shower.
• If it's a phone interview and you plan to use a cellphone, make sure your phone is fully charged and has good signal strength.
• For an onsite interview, or an offsite interview where you have an appointed time, it should be plenty obvious that you must arrive on time.
• When you meet the interviewer for a face-to-face interview, try to initiate the greeting as well as handshake.
• As you talk to the interviewer, it's vitally important that you maintain constant eye contact, meaning you look him or her in the eyes.
• As you make eye contact, you should also smile from time to time.
• Candidate's communication skills.
• Speed of speech is important.
• Speak clearly.
• Your body language is important
• how you sit
• how you listen to
• how you properly use your hands

A jog interview is a two-way exchange: the interviewer examines your qualification, and you, the candidate, find out if the job and the environment are right for you.

• intelligent questions
• questions that can actually flatter the interviewer
• questions that you really care about

#### Tips for Short Interviews

• be likeable
• size the opportunity and drag the interview into your comfort zone
• you might want to make some deliberate (but harmeless) mistakes, to allow the interviewer to point them out, which in turn allows you to talk and talk and talk
• if you are given a difficult technical question, work through it as fast as you can, but make sure you don't lose precious time on any particular step.

#### Tips for Long Interviews

The best way to prepare for long interviews is to know your stuff well, the stuff here being all those skills your resume says you possess and the quantitative education your resume says yuo undertook.

For long interviews, the closing is especially important.

#### Dealing With Difficult Questions

Answer the tough question truthfully, politely, and confidently.

• modeling know-how: from theory to empirical techniques to programming aptitude
• short technical questions: define some concepts and solve a quick problem
• long technical questions: more advanced concept or longer problem to solve
• think out loud
• you need to know when you get stuck

#### Handling Case Questions

• case questions are actually not common at quant interviews
• some quant interviewers do ask case questions
• No right or wrong answers but they want to see how you think
• Every problem requires two major steps
• identifying the issues
• comming up with solutions to these issues

As mentioned before, a subtle yet powerful efffect of thinking aloud is you turn the problem solving itself into a collaborative effort, with the interviewer acting as your senior partner (since he or she knows the anser). Thus, you also prove your teamwork ability. One stone, two (or is it three?) birds.

In other words, don't use a job interview as the time to show off your creativity or originality.

• types of case questions
• involes using quant skills to solve a fairly big problem
• brainteasers, puzzles that test your general logical reasoning without resorting to technical skills
• how to approach case questions
• rephrase: make sure you and the interviewer are on the same page regarding every detail
• it's the thought process that counts / thinking out aloud

#### The Dont's of Interviewing

• don't be late
• don't show up in casual wear
• don't forget to bring a copy of your resume
• don't forget to make eye contact and smile
• don't argure with the interviewer
• don't look or act arrogant
• don't be too aggressive
• don't interrupt the interviewer
• don't act clownish
• don't ramble or BS
• don't overuse excuses
• don't put on an act
• don't talk too much
• don't read off index cards
• don't lie
• don't forget to send your interviewer a thank-you note

#### What to Do If Interview Not Going Well

First, don't forget to shate the interviewer's hand at the end and offer thanks in a sincere tone. Second, don't forget to send him or her a thank-you note when you get home.

#### Interviews That Are Not Interviews

• written exams
• fun group event

## Education: Arm Yourself with Knowledge

#### Basic Concepts of Quantitative Finance

• Quantitative analysis
• subjects: mathematics, statistics, econometrics
• theory and empirical work / 知其所以然
• Finance
• fair pricing of assets
• different assets
• equity
• bonds
• commodity
• derivatives

• Conduct background material search via the Internet
• Verify basic mathematics in the model
• Help collect data
• Get involved in testing and debugging the model
• Assist in putting together product presentation

#### Must-Take Courses in College

The first thing to keep in mind is that Wall Street recruiters like to see candidates who take on challenges and grow.

• Mathematics
• calculus
• linear algebra
• Statistics
• probability theory
• basic statistics
• Economics
• microeconomics
• macroeconomics
• international finance
• Econnometrics
• regressions
• hypothesis testing
• time series models
• Finance
• investment theory
• different assets
• financial modeling
• Computer science
• C++ / C# / Java
• algorithm design and implementation

#### Quant Opportunities for Grad Degree Holders

• senior quant v.s. junior quant
• modeling experience and finance knowledge

• general-purpose programs
• mathematics
• applied mathematics
• statistics
• economics
• econometrics
• finance
• specialized programs
• quantitative finance
• methematical finance
• financial mathematics
• financial engineering
• analytical finance
• author recommends specialized programs because
• training relevant to the fruture career as a quant
• comprehensive coverage of the various areas of quantitative fiannce
• taught by industry veterans
• internship positions

#### Ph.D. vs. Master's

Ph.D. graduates should hold no illusion that Wall Street is a haven for intellectuals: it's only a haven if you can use your brain power to make money for your employer; otherwise, it's quite a cruel place to be (highly stressful, super-competitive, intoxicatingly money-crazy).

#### Must-Take Courses in Grad School

• Mathematics
• calculus
• linear algebra
• differential equations
• computation mathematics
• operations research
• applied optimization
• Statistics
• more focus on the econnometrics instead
• survival analysis
• Economics
• more focus on the finance instead
• stochastic process
• Econnometrics
• non-linear models
• non-parametric methods
• time series
• statistical packages
• Fiannce
• continuous-time finance
• Computer Science
• algorithm-heavy course

### Chapter 7: Self-Education

#### Power Reading List for the Impatient

The books recommended in this section are must-reads because they cover exactly the kind of quantitative knowledge you need to know if you want to become a Wall Street quant.

#### Computer Science

• general programming: C++ / C# / Java
• data-processing language: Perl / Python / SQL
• IT knowledge
• Microsoft Windows / Linux
• Microsoft Office suite
• VBA
• Shell programming

#### To CFA or Not to CFA

• The CFA is largely a buy-side phenomenon; few people on the sell side care about the title, let alone go for it. In particular, the CFA is popular among people whoe work in asset management such as mutual funds. The three CFA exams and the necessary preparations for these exams cover a wide range of topics in finance, but the emphasis is far from the kind of quantitative analysis (mathematical and statistical modeling).
• Readers aspiring to be quants should enroll in a quantitative analysis-heavy graduate program.
• Becoming a CFA (or just passing the exams) can never be disadcantageous.

## Experience: Acquire Real-world Skills

### Chapter 8: Working While in School

I highly recommend a real'' job if possible.

#### Quant Internships

• part-time job and full-time summer job
• suggestions
• start early
• internship positions are usually unadvertised

Many internship positions are rewarded to applicants who come in through contacts or cold calling.

• what employers look for an intern are
• enthusiasm
• intellectual curiosity
• maturity
• obedience
• An internship also serves as a self-discovery tool. A Wall Street career is not for everybody.

The only advice I have is, get involved in empirical research projects, not theoretical ones.

### Chapter 9: Already a Full-Timer

• any quantitative work before?
• is your quantitative knowledge relevant to the quant job you'd like to have?
• the most important qualification for being a quant
• smart
• willingness to work hard

#### Skills and Starting Position

Try to find a job that will take maximum advantage of your existing skills.

## Bright Future: Go Far and Prosper

### Chapter 10: Evaluating Offers and Starting Job

#### Oral Offer vs. Written Offer

You should always wait until you get the official written offer in the mail before you decide whether to cancel any other impending interviews.

It's adequate to simply thank the caller (eg. HR manager) for the information.

#### The Money Game

• base salary
• corporation titles
• exempt'' employee
• bonus
• market conditions
• the firm
• the department
• the group
• the job
• exagggeration / firm-wide bonus pool

For us mere mortals, keeping expectations low is probably the best strategy.

• signing bonus

#### Resting Days

• vacation days
• the number of vacation days varies greatly from firm to firm
• whereas companies used to make a distinction between vacation days and personal days
• what you are entitled to may not be what you can actually get
• almost all firms allow you to roll over some unused vacation days from year to year, but there are ususlly strings attached
• most big firms allow you to cash out your unused vacation days when your employment terminates
• sick days
• other day off
• marriage
• childbirth
• family death

#### Titles and Positions

• corporate titles
• analyst
• associate
• assistant vice president
• vice president
• senior vice president / director / principal
• managing director
• top corporate excutives (eg. the CEO, the COO)
• functional titles
• quantitative analyst, quantitative developer, financial engineer, quantitative trader

#### Negotiating Offers

First of all, you should know that every offer can be negotiated.

Never lie about having another offer.

The important thing is, call them. Do not use e-mail, as e-mail is totally ineffective for negotiating anything.

Never try to insinuate a threat.

• honeymooon'' period and daily routine
• coworkers

Be sure to leverage the experience and knowledge of your coworkers - which, of course, also means you should be frineds with your coworkers.

• boss

It's vitally important you understand how your boss thinks.

If a faceless Wall Street firm has a personal side at all, it can be found among the HR people.

• office politics

When you have conflicts, there will be politics.

At the beginning of your carrer, it's probably best to stay away from such distractions as much as possible.
