I just received the most recent copy of Les Rosens' book, The Safe Hiring Manual.
I must say that I am very impressed as the book has expanded to many pages, even larger international and EEOC sections.
No one is a 100% expert in all things pre-employment but as a reader you can learn from what he (Rosen) has written and incorporate some of it into your screening program.
Les Rosen's book is available from BRB Publishing (www.brbpub.com)
