This book was mentioned on the JavaPosse’s podcast this week – it’s a collection of sample Java SE and EE type questions that are commonly used in interviews for developer positions, and would be useful for both interviewers and interviewess as a good source of information.
The site it is hosted on is also worth a look as it is an interesting concept – Lulu.com is a community publisher site. You can upload your own book content to be published on the site either for free or for sale, and the site offers it either for download or can print one off copies for people to purchase.
