got scheduled through third party, it was for AmEx client. two technical round - first round was pretty good, questions were asked related to projects , bigquery, sql , python . but the second round was idk what, i guess he didnt want to hire. stopped me in first line of introduction itself , was very rude, asked questions related to pyspark - solved, 2 sqls - solved, airflow dag creation - solved, then he was getting into topics like dataflow - i wrote a full apache beam pipeline , he said great!! and then what - rejected! no detailed feedback, nothing - just - you are not selected! crazy people
