In the past months Adobe has released 2 exams for CQ5 developers:
- CQ 5.5 component developer exam (altough the name might imply, this exam does not only cover the development of components and templates!)
- CQ 5.5 lead developer exam
Both exams cover a broad range of topics regarding CQ5 and its building blocks. For most developers surprising, also sysadmin related questions are asked, like details on the dispatcher configuration. The topic list in the referenced PDFs are quite comprehensive and give you some good overview which areas are covered by the questions. Be prepared to answer some questions down to the property level… And just as a warning: You need practice experience with CQ5, from my point of view you cannot pass with just having attended all trainings!
I wish you all, who want to take that exam, good luck. It’s doable.
