If I needed to learn enough about building data lakes in Google Cloud Platform using Airflow as an ETL to be able to talk intelligently about it before Monday, what would you recommend?

I already know plenty about data lakes and ETL itself, but I've never used GCP or Airflow. I have an interview on Monday for a data engineering position, and I would like to be able to talk intelligently about these two products before then. Does anyone have any experience with either of these two and could provide some pointers on where to go to find good documentation?
