There were three rounds of interviews. In the round 1 of data engineer role, the interviewer asked me questions about sql, Why sql is used and basics of sql. And then asked to rate myself in both Sql and Dsa. The interviewer then asked me to write a code for the two sum leetcode question in dsa and a basic sql question( aggregate functions ). And then asked me if I have any questions to ask. I was not selected for R2.
