Buying this interview guide will help you prepare for the type of questions you are most likely encounter during a technical interview. It is not a silver bullet but the questions and their solutions are quite representative of any quant interviews. The actual questions you might be asked might slighty differ from the ones in the book, however the way to approach them is the same and there are only so many ways a problem can be posed. They might keep adding complexity to the question to see you handle it.

There is a lot more to landing a role than technical skills and this guide can't help with those, namely cultural fit and communication skills, which are very impotant. Rather often it's these soft skills that make the difference between an offer and a rejection.

Competition for quant roles is extremely high and training with this guide will significantly improve your odds of landing the job. While it is not a replacement for strong quantitative skills, it will serve any student or professional and the purpose rather well.
