Interview experience @olx

Hey folks, just cleared R1 for the Data Engineer 1 role at Olx. Heading into R2 and wanted to get a vibe check on what to expect. Is it heavy on LC style DSA (Trees/DP) or does it skew more towards advanced SQL and DE concepts (Spark/ETL scenarios)? For context: I have 2 YOE. Any recent experiences or specific topics to brush up on would be super helpful. Thanks!
