It's more about the reaction by obvious scammers.
The scam is hold on to the job for at least 1 paycheck. It’s a expensive for companies to (legally) fire people, so if you get hired you typically can get at least a few grand even if you do zero work.
Maybe in Europe, in the US it's an email.
So just produce LLM-level code, make excuses, say you’re learning the code base, get lots of help from colleagues, turn in mediocre work, and if you can hang on for three months before they fire you - that’s decent money!
If they switched from doing all this to pressing people for estimates.
