If a SW dev applicant gives a 20-file generated output for a 20-line assessment problem and can't explain single lines of "their" code, either what they should be doing or why "they" had written it, it's gonna be a no from me, dawg. A standard problem might have different solutions, but fixing the issue of the day to the satisfaction of a rabidly vocal customer base might have one at most, and it will change multiple times on a whim.

So the LLM might have helped them cheat their way to an MSc, but there's no cheating your way through real life.
