I haven't done the Kentico certified exam for over two years - but this doesn't make me any less of an awesome and competent Kentico Developer. Over the last two years, a lot has changed within the Kentico realm resulting in the subject matter becoming a little more of a challenge to keep up to speed with. Afterall, two years ago we saw the dawn of a new age - the end of Kentico 7 and the start of Kentico 8. I am seeing the same thing happening again, except this time we're just about seeing Kentico 10 making it's appearance over the horizon.
What I noticed this time round was the increased number of questions evolving around macro's. It felt like I was bombarded at the time of carrying out the exam. I think the only thing that got me through is remembering the approach I took to the macro's I wrote for a recent EMS project.
The Kentico Certification Preparation Guide has greatly improved compared to previous versions where in the past questions were pretty simple and a vast contrast to the real thing. This allowed me to gauge a lot more on the type of questions that would potentially be presented, but I did notice quite a few questions from the preparation guide cropped up in the real exam - although slightly re-worded.
I highly recommend anyone who is interested in becoming a Kentico Certified Developer to read the following post by Jeroen Furst prior to taking the exam called: Tips for becoming a Kentico Certified Developer. Jeroen brings up some really good points and guidance to prepare yourself. If only I came across this post two years ago when I wasn't too sure what to expect (being my first Kentico exam), I would have felt more comfortable in understanding what was required.
I was expecting there to be some questions relating to MVC due to all the effort made by the Kentico development team to make the MVC integration seamless within Kentico 9. Alas, this was not the case. Jeroen also states the following:
If you are planning to take any older v6, v7 or v8 exams (if still possible) you might run into questions regarding Azure and the Intranet solution. These topics are not part of the v9 exam anymore.
The Kentico 9 exam purely focuses on the core Kentico features as well as the platform architecture every Kentico developer should know in order to build high quality sites. You will also find yourself learning some new things in the process of preparing for the exam as well as brushing up on your existing knowledge.
If you succeed, you can proudly display this badge in all its glory! ;-)
