Heard on the Street: Quantitative Questions from Wall ... (ISBN 0970055250)

Decent:
This is a decent book. I only looked at a couple of chapters on analytical and statistics problems. Some of the problems marked "hard" were quite interesting and challenging. Quite a few of the problems were trivial and repetitive though. The solutions are generally well written, though sometimes a bit too verbose (for my taste). Overall, not a bad investment if you are preparing for job interviews which may expect you to crack a few puzzles.

Very useful book:
I wished I had read this book before I attended a very important exam of an investment bank. A lot of questions are from this book.

very helpful:
I think this book is very useful even just from the perspective of finding something interesting to do when you get bored. Not mention it indeed provides a lot of relevant information about how to answer the interview quesionts.

it gives me new growth:
It have best questions and puzzles, I always enjoy when i open it, it gives me new growth.

Good enough to get you started:
A good reference to get all revved up for what's coming your way on the journey to quantitative Wall Street?
