I applied online. The process took 1 week. I interviewed at LetsGetChecked (Portugal) in Dec 2021
Interview
I had a one-hour technical interview focused on data engineering concepts, such as ETL pipelines, data modeling, and SQL optimization. Following that, I completed a technical challenge involving real-world data problems, like cleaning and transforming datasets. Finally, I participated in another interview to present and explain my solution, discussing my approach, tools used, and potential improvements.
