I respect your view but disagree. I use pandas everyday for my job. I use spark. I use keras. I use scikit. I use all these APIs everyday for my job. I can't think of the last time I loaded a file using vanilla python. If it's a requirement for the job (which it wasn't, they showed me pandas code later) then I completely understand and would not be qualified nor would I want the job. There's a few things going on here. First, there's a frustration from the interviewer who is obviously looking for the cookie-cutter answer to move things along. Second, there's a culture misalignment because they are looking for cookie cutters to do the job while I am not that. Third, they, along with OP, are obviously not a palindrome company nor a load-everything-to-lists company yet this is what they're testing. So again, culture misalignment. At the end of the day, you are right, I self-selected myself out because I would not be happy at a place like such who are looking for cookie-cutter employees.
