Interviews are not necessarily a true reflection of a person's nature, it's a game of deception to acquire a position, interviews are dishonest from all directions. Perhaps the candidate will show their true colours and sabotage their future, or they could turn out to just be a decent applicant who was doing their best to get a job in a difficult time to seek employment. Time will tell, it may have been best not to project any loaded questions or to dig too deep into their personality.
