Fractal Python Data Analyst interview questions

Given tech test with very specific instruction but the person who assesses have his very own set of the specification which he will ask why you did not do that. In test specification, it says do as we say nothing else. The person did not understand how persistent data volume works in Docker and complaining i was wrong. A simple google search would have showed him that. Then after I submit my code they say now the position is on hold after I waster 8-10 hrs my time.
