An AI interviewer works from a question set built for the role, such as availability, right to work, relevant experience and a situational question. Unlike a fixed form, it can ask a follow-up when an answer is vague, for instance asking which tills a candidate has used after they mention retail experience. The conversation is usually saved as a recording and transcript, with each answer scored against the role's criteria.
Because every candidate hears the same core questions in the same order, comparisons are fairer than a set of rushed phone screens done by different people. Candidates can usually take the interview at any hour, which helps shift workers and people with caring duties. The safeguards that count are telling candidates they are speaking to AI, keeping questions job-relevant and having a recruiter review results before anyone moves on.
