Technical interview tomorrow with IBM

Hi Guys, I have a technical interview scheduled for tomorrow with IBM. ~4 yoe. Currently working with accenture as a data engineer. I have experience in SQL, Google Cloud Platform, Big Query, Airflow, ETL, SSIS Packages. The HR mentioned the opening is specifically for Airflow and cloud knowledge which I already have. But as this is my first interview post joining Accenture as a fresher so I'm a bit nervous. Any seniors who would like to help on the questions I can expect in this domain and any mistakes I should avoid in an interview would be very helpful. It's a 30 minute interview call. Please let me know if you need any further inputs to help me out.

Thanks much in advance!
