Our interview usually starts with them breathlessly reading from a script out of the corner of their eye. I'm ok with notes to make sure you hit some high points about yourself even in person. Nervousness shouldn't disqualify a talented person. But with the coding part I've gotten exasperated and started asking these senior candidates to share their screen and do a fizz buzz exercise live in a text editor in the first few minutes. If they struggle I politely end the interview on the 15.
One candidate cheated and it was interesting to watch. In the time I sent the message in Zoom and them sharing their screen, just a few seconds, they had either queried or LLM-ed it on their phone or another computer, had someone off screen or in the same room listening and sharing the answer on another monitor or something else. Whatever it was they turned their head slightly to the side, squinted a bit and typed the answer in Java. A few syncopated characters at a time. When asked what modulo was they didn't know and couldn't make any changes to it. It was wacky. In retrospect I think it was them reading the question out loud to an LLM.
I'm waiting for the candidate who has someone behind them with the same shirt on pretending to be their arms.
