Re: This will limit their pool of candidates...
The main reason for these AI- or algorithm-based recruitment processes is to remove the human-element, because humans *suck*. They have a really difficult time setting aside subconscious biases they will influence their decisions, even if they are not aware this is happening.
You describe how to manipulate a human recruiter yourself: By asking questions yourself you become more memorable, and thus more likely to be considered. Does asking questions make you any more suited to the job? Probably not, but by making yourself more distinctive you give yourself an advantage over the dull-as-dishwater candidates who are just as qualified.
Everyone who has sought a job knows the basics of manipulation. The smart suit, the fresh shower and haircut - those little aspects of appearance that bear absolutely no relation to the job, but still bias the recruiter into judging you to be more professional.
