I think they wanted me to look for a "__name__" check against "__main__" because they moved on the moment I opened a search bar for "main". However that's not necessary, regardless of how the code is called. There really isn't anything that would stop a python script from running apart from code errors, but it was a long script so I assumed they didn't want me to debug it for a Support position. Instead I just checked for a requirements.txt and package availability since, technically, it wouldn't run until the imported packages were available then moved on to random checks like searching for "main"...vague question and I'm pretty sure they were expecting an incorrect answer, part of the reason the interview is labeled as "difficult" since it's hard to know what wrong answer an interviewer wants.
