M2 Certified Professional Developer test is here for a while now and I finally got some time to prepare and appear for this test. It asks you 60 questions which you have to answer in a time limit of 90 minutes. So basically you get 1.5 minutes to answer each question. Though you should not waste time if you are able to answer the question quicker, as there are many questions in the test which are lengthy and requires more time to understand the question. If you are a non-native English speaker, you may have to read some of the questions 2-3 times before fully understanding what it is exactly asking. Passing score is 64% – so you need to get 39 correct answers out of 60, which is almost 2 out of 3 questions. At the end of the test, you get the score on screen which is great to know instantly if you passed or you need to re-take the test.
Yesterday I took the M2 Professional Developer test and passed it. I found it difficult to be honest, questions were lengthy and answers were confusing. Magento recommends developers to at least have 1.5 to 2 years of experience before taking this test to pass, but I think you can still go for the test if you have worked on 4-5 Magento 2 projects hands on with around a year of experience. I believe that is enough if you are fully into Magento and understand the architecture of the system and technical concepts of various features it offers.
I found SwiftOtter very useful, along with it’s practice test where it offers 44 questions https://swiftotter.com/technical/certifications/magento-2-certified-developer-practice-test. However, it’s not guaranteed that you will pass solely by studying their guide and practice test. You also need to understand the code and should have experience working on it in the M2 projects to clear the exam. I suggest taking the practice test once you have read and understood the topics in the guide and Magento DevDocs and are ready to face the real test.
It’s evident there’s a lot of hard work done by the Magento U team and developers who contributed to this test by writing questions and answers. It’s really hard to pass this test if you don’t have deep understanding in Magento 2 concepts and don’t have enough practical knowledge to prove your M2 abilities.
I think this test could have done even better if it had also focused on:
Security – Not a single question was asked on this topic. I am not talking about Payment, PCI and Magento Vault things when I say Security, I mean writing code that does not leave behind security vulnerabilities. It should be must for a backend or full-stack developer to at least have a basic understanding of how to write secure code, Magento had a great opportunity to include some good security questions (like CSRF token, escaping user-submitted data, XSS prevention, preventing file path exploits, sanitizing user data before saving/getting from db, etc..) here, but….
Readability – Most of the Magento developers are from non-native English speaking countries, myself included. I feel there were few lengthy questions which were just difficult to understand for non-native speakers. I also heard similar complaints from few developers who took this test confirming that they had to read some of the questions 2-3 times which took much of their time to just understand what the questions were trying to ask. That’s a disadvantage to many developers and I believe Magento U will take a note of that when writing upcoming new test questions.
Let me know your thoughts! Kudos to Magento U team for creating such an outstanding test.
