Yesterday I had a questionable pleasure of interviewing a young software engineer who (while answering one of earlier questions) used a principle of polymorphism but made a mistake. So I asked her to explain what polymorphism is.

She couldn't. When she said "let me start from the beginning" for the 3rd time I jestfully noted that if she's more used to virtual communication she can text me the answer, and she not only thought I was being serious but also thought it's a good idea, then texted me a duck emoji, a dog emoji... And got stuck again.

Obviously when we were discussing potential salary she had an answer for every question. Ridiculous answer but no communication issues whatsoever.
