The wasting of the applicant's time while applying for a specific job I think should be the secondary concern for the applicant in this system.

The primary concern should be volunarily feeding your personal information to the intermediate AI interview Saas companies along with the backend SotA AI model suppliers (OpenAI etc), so they can turn around and sell your personal info as premium services to the companies you're applying to, revealing which other companies you applied to, how many companies you have applied to, and your performance in those interviews allowing the companies that are paying for that premium service to filter you out, shadowban you, or lowball you based on that information.

And since you never talk to another human, you will never know whether the AI flagging you as a bad applicant pretty much nuked your chances for future jobs.
