It will be available on Amazon in about 4 weeks. It takes time for the book
to reach the retail distribution channel -- nothing we can do about it.
When it's available on Amazon I'll make an announcement on my blog.

Even though I was involved in the book project, I can objectively say this
is a very good book with over 200 *REAL* quant interview questions -- and
detailed solutions. Xinfeng, who spent almost 2 years on the project, is a
quant strategist at one of the best IBs on Wall Street; and he used to work
at BGI, a top buy-side firm.

I agree with you and Angel. Books like this do push more and more quant
interviewers into coming up with weird questions. On the other hand,
speaking from my own first-hand experience, there're some questions that
always show up.

But... the most important point is, you're not supposed to memorize the
questions and solutions! You're supposed to study how to approach the
solution -- from analyzing what's being asked to coming up with a
methodology to finally having a good answer.

Ask any of your friends who want to get into management consulting -- they'
ll probably end up reading 3 or 4 thick case-question books! The truth is,
high-paying industries like finance are getting more and more competitive --
esp. when the job market isn't good -- so in a sense, every bit of help can
be valuable.

This is just my 2 cents. I'm not here to sell the book, but I do think
Xinfeng has done a good job.

PS: thanks for your compliment! :-)

You raised a very good question.

But, first of all, I do not think it's wise to refuse to answer technical
questions at an interview. I mean, if a person intrudes on your privacy and
asks you, for example, "how many girlfriends have you had?" I think you
have every right to refuse to answer that -- and you should tell the manager
, the headhunter, and HR about such ridiculous questions.

But if it's a technical question, no matter how "stupid" you think it is,
you must try to answer it, if you want the job. Even if you don't want the
job, I do not recommend you "burning the bridges" and leaving a bad
reputation. On Wall Street, bad reputation travels fast. If you're really
smart and already successful, then people can forgive you. But for most of
us -- yours truly included -- we do not enjoy such a luxury, so it's better
to play by the rules.

Do these questions test your ability? This is the same as asking "Does SAT/
GRE/TOEFL/GMAT test a student's knowledge and aptitude?" I don't think
there's an easy answer. All of us have standardized tests to thank for
being where we are today -- so why do you want to challenge an interviewer's
technical question, no matter how far-fetched you think it is to the job at
hand?

All interviewers know how difficult it is to find a suitable candidate, or to judge a candidate's competency. Everybody's resume is more or less the same -- esp. among fresh graduates. You just need some way to differentiate among the candidates.

Finally, as I mention in my book, interviewers often use tough questions to
gauge how a candidate acts under duress. For this reason alone, even if you
can't answer a question, you should put up a positive attitude. Someday,
when you're successful enough to snub others, you can then tell an
interviewer who gives you a hard time to "up yours" -- but before then, act
normal and act well.

Good luck!
