The same for job interviews. I did a lot of technical interviews in the past as interviewer (hundreds) for Software Engineer positions (and still help companies to hire sometimes, as independent interviewer).

There is insane amount of cheating. I'd say at least 30% in normal companies are cheaters, and 50% and more in FAANG. I can prove it, in private groups, and forums people share tech assignments. And very large number of these people use some kind of assistance while interviewing.

It's interesting to see how sometimes questions that are intentionally sophisticated are getting solved in a few minutes the best way they can be solved. I see this over and over.
