[Question] Asking extremely basic questions to win arguments—Name the bias or the fallacy at play

Recently I went to a product manager interview.

They asked a few questions, for which I gave the answers. But eventually one interviewer asked extremely trivial questions i.e. first year of graduation questions—How does the wifi router work? How does DNS work? How does internet work? These questions are so generic, trivial and basic but at the same time, nobody can remember everything. These questions do not require you to use your logic either. It is a simple memory based question. But since I wrote the answers to these questions over 10 years ago, it is impossible for me to remember them. I understood the bias at play here, but I could not give a name to it. There might be multiple fallacies or biases at play here. Can you please help me pin point them?
