✨Of course your experience in recruiting is the best friend to face this fear with. Try to find a key to the applicant's soul and reveal who's a liar. Unstandard questions can help you with that — use those that reveal a candidate's personality. Like, what movie would describe them best or what would they like to change in themselves.
Here you can find more such questions. You can ask these questions even remotely, before meeting the candidate: just ask them to record video answers to your questions, and customize the questions not to be re-recordable.
