It is a good book, but very out of date now.
Read as much as you can as all the information you can gather will be of use in the technical interview.
If you go to the CAA's webiste, and go to the Publications, then Air Traffic Services section, you can download a copy of the Manual of Air Traffic Services pt.1. This book is the guidelines that ATCO's in the UK operate to, and is the main text book used in the college.
