Why would anyone encourage building such a tool, I can't fathom.
I can totally understand thinking this way out of desperation, and being lulled into thinking it’s this simple, but it seems short sighted with hidden complexities. First of all, it’s risky. If you get caught, you don’t eat, and it could follow you and prevent you from even getting in the door elsewhere. Companies are always going to be watching for cheaters, they are always going to have more visibility than you into what interviewees are doing, and they are always going to have more resources. Even if you do cheat and get hired, it quickly becomes obvious that you’re unqualified and can’t do what you claimed, and even if you don’t lose your job, you’re less likely to get promoted. Being lazy and amoral about interviews seems like a trap people set for themselves.
The good news is that a lot of companies are starting to allow AI during the interviews, and suddenly it’s not cheating. But of course that means you need to be good at using AI and interviewing and programming, you won’t be able to cheat and rely on the AI to do your talking for you.
