I was extremely curious to understand this guide as it was acclaimed as a top #10 best amazon best selling book - and hastily understood why some new recruiters and people of the field come practices and\or ideas of the interviewing process that seem to come from the stone age.
The book itself focuses a lot of social\volume\health type of recruitment and doesn't overstate that much into other areas. With this being said, someone picking up this book can get some positive highlights of the ways things are done in theserecruitment fields, but what is more concerning is that if you're wanting to recruit something in a more STEM-related field and use this to base yourself in recruitment - you'll struggle, hard.
The book is a very focused point book that requires understanding the author (start with the last pages) before you jump into the book itself if you want to read it. But the best practices, newer techniques and strategies come from the place where most of the people don't just apply to a role but you have to reach back to them.
All in all, the book is very simple to read - I didn't take much time even though I was not invested in it. Some of the theoretical knowledge is very outdated (even for 2017) in various fields of work already so tread carefully on this, also, its an extremely formal approach to the process with a lot of author-based experiences and reactions.
