Docker Devops Engineer interview questions

Started with a screening call, followed by a ~30 minute technical call. A coding project was assigned. I completed the assignment, gave access to my git repository, and published the app live on my own public cloud infrastructure for good measure. 3 technical interviews followed, where we discussed my code. The final interviewer took issue with 1 aspect of the code; admittedly, the approach was not ideal, which I had noted inline with comments explaining that it was brittle and not my best work, but that it *did* work to fulfill the requirements, and it would be the first improvement I would make if I had more time to spend on this. The interviewer seemed to believe that the code didn't work; the same code I had deployed as a fully-functional web application. He put a hard stop on my candidacy, in spite of the hiring manager's enthusiasm, the clear approval of every other interviewer, and my clearly demonstrated capabilities.
