This blog is more of a quick reference notes rather than a real blog. I shared this with few Google internal folks and since they found it useful, I thought I will share these notes in the blog as well.
Please note that the Data engineer exam format changed a little from March 29, 2019. I took this exam in January 2019, so some of the notes below might not apply. The 2 big changes from before are that there are no case studies in the new format and certain new data and ML products like composer, Automl, kubeflow have been introduced.
There are many references on preparation steps for GCP Data engineer exam. Why am I writing 1 more? What I found reading through an individual’s experience is that I always get some new insight. I am hoping that this write up would help some new person preparing for the exam.
I cleared the exam last week of January 2019. I come from an infrastructure background, Data engineer was not my area of strength and this needed around a total of 8 week preparation time for me. The 8 weeks is not a dedicated time but few hours split over a 8 week period. I have been with Google cloud team for 1+ years and I found that the practical experience is important for the exam.
The exam is an objective choice with 50 questions to be done in 2 hours time frame. There are also questions asked regarding the 2 case studies. For my preparation, I used the data engineer modules of Coursera training and Linux academy. It will be good to review and breakdown the case studies beforehand so that we can avoid spending time reading the case study text in the exam. Qwiklabs and the labs associated with Coursera helps quite a bit. I have added the links in the references.
The certification tests both the theoretical knowledge as well as practical knowledge using the GCP products and technologies. My suggestion is to take the exam after getting some practical experience with GCP. Another thing that I noticed in the exam is for some questions, more than 1 answer would seem appropriate and it takes thorough analysis before answering. 1 tip would be to mark these questions for review and spend time on these after answering all other questions.
