Data Engineer - Professional
GCP
Maybe the biggest certification for Data Engineers on the cloud, specially the beta one! This was by far the hardest test I have done in my life, everything was doubled in size, 120 questions and 4 hours of test (60 and 2 hours for the normal test) and no available courses for the updated content, very unfair to your mind since you can't go to the bathroom during the test. I learned the beauty of studying through documentation.
