This is an extremely encouraging resource full of excellent information both for people who are actively looking for a job as well as for folks who have a solid position now (because these days, that can change in the blink of an eye).
With a style that I found very easy to read and approachable I got through the book in under a week, and I am not a particularly fast reader. Actually applying the material is another matter--but I consider that a good thing, because there's a lot to engage with! Before I read Reverse the Search, I had a resume that I had poured hours into, trying to strike the perfect balance: keep it brief, but still showcase the skills and capabilities that I've honed over the last 10+ years. After reading this book, I realized I still have a lot of work to do: in the effort to show employers how versatile I am, and what a wide range of expertise I bring, I had hollowed out my resume to the point where it says almost nothing useful to recruiters! Thankfully, in addition to shining a bright light on the issue, the book also has a straightforward guide to write resumes that will get you noticed (at least, theoretically; I am still working through the revisions--they're straightforward, but when you've been working for as long as I have, they're also extensive!)
I consider it time well spent, as I'm refamiliarizing myself with some of my most impactful work. This not only will help the resume better represent what I bring to the table; the book also provides salient advice for preparing for interviews, which can be done at least somewhat in tandem with the resume work.
It also provides useful guidance for networking. I have yet to leverage that as extensively, as I'm currently focusing on the resume portion, but I have been working on cultivating those connections as well--IMO this is likely the best place to focus if you already have a job at the moment; it can help you find (and maybe even get introductions/interviews/positions) better opportunities, as well as reduce the time it takes to find a new position if your employment circumstances take a sudden turn for the worse.
In conclusion, I greatly enjoyed Reverse the Search and it has given me increased confidence that when the time comes for me to get a new job, I'll be ready!
