I've had this book for about a year and am interviewing again after taking a bridge job. I've read other books on the subject of job search, but none are as useful as this book for several reasons.
First, this book does a great job of being concise, which is what the job searcher needs. When you're laid-off or trying to search for a job while balancing work, family, and life, you want shorter chapters than can be quickly gleaned for action items and job-search goals because job search is stressful and it becomes easy to get stuck mentally.
Second, this book is great for helping the job searcher clarify what they want out of work. You spend over half your life at work, so your job better be something for which you have aptitude and interest. Not only that, but the job search itself is a big self-marketing game and knowing what you want and what you're good at makes your sales pitch (of yourself) that much better and more fluid.
Third, as I said above, the job search is a game of marketing yourself. You can't just send in a resume and expect anything - you have to figure out how to get your resume in the hands of someone who cares (not HR). This means that you have to do a lot of creative sleuthing and have your sales pitch ready when you actually get someone on the phone with you. This book dispels the notion that emailed resumes, cover letters, and online job applications will get you anywhere.
Lastly, this book does a great job of teaching you how to control the flow of discussion in an interview. It does this by teaching you that you, the job searcher, are picking jobs rather than allowing the manager to pick you. You are trying to determine if a job matches your skill set and interests and should ask questions accordingly in an interview. You must also interview your next boss to see if he's someone you would work well with. Once you adopt this frame of mind, as the book promised, you will start hitting interviews out of the park. At least, that has been my experience.
Like I said, I've read other books on this subject - including bestsellers - and they left me spinning my wheels in "analysis paralysis." This book actually gets you out of your rut.
