The findings help shed a light on how recruiters can help their candidates prepare for interviews and the potential challenges that they may face during the process. Almost half (49%) of interviewers said they have intentionally asked difficult questions while interviewing a candidate. Interestingly, 20% admitted they’d adopted negative body language and 17% said they’d acted disinterested on purpose to throw the candidate. Worryingly, 20% said they’d asked personal questions to test a candidate.
