Job interviews used to happen during business hours because a human had to be sitting on the other end of the call. That is no longer true. A recruiting company called Ribbon reports that a quarter of the AI interviews it runs happen between 10 pm and 2 am, and for its manufacturing clients that number climbs above a third. Another major hiring platform, Greenhouse, sees 15 to 20 percent of its AI interviews booked at night.
The reason is simple. An AI interviewer does not need sleep, a lunch break, or a scheduling assistant. That is genuinely useful for parents, hourly workers, and people currently working a factory floor or a kitchen shift who cannot take 30 minutes off during the day. For them, midnight is not a punishment, it is the only slot that exists.
But the bigger story is what this reveals about the state of hiring generally. Job seekers are stuck between two automated systems working against each other. Companies use software to screen resumes before a person ever reads them, and about 82 percent of companies say they already do this. Candidates responded by using AI to write those resumes and cover letters, and now AI is being used to answer AI interview questions in real time. One hiring expert described it as companies filtering applications with AI, then candidates using AI right back as a countermeasure. Everyone is now negotiating with a machine, not a person.
The trust problem is real and measurable. A recent Greenhouse survey found that most job seekers were not told an AI was running their interview at all. Nearly four in ten American candidates say they have already quit a hiring process specifically because it involved an AI interview. Yet companies are not slowing down. Most plan to keep expanding AI in hiring over the next year, including for asking interview questions directly and analyzing how candidates speak.
Regulators are starting to react. Illinois now requires employers to tell applicants when AI is involved in hiring decisions and to get written consent before using video interview software. New York City requires companies using automated hiring tools to run an independent bias audit every year. These rules exist because complaints are already showing up: a discrimination complaint filed against HireVue and Intuit in 2025 alleged their AI interview tool disadvantaged deaf and non-white applicants.
For business operators, the practical takeaway is not that AI interviews are good or bad. It is that the technology has moved faster than trust, transparency, or the law can keep up with. Any company using AI to screen candidates should assume regulators, applicants, and eventually lawyers are watching closely. The convenience of a 1 am interview slot is real. So is the risk of running a hiring process candidates increasingly do not believe is fair, and increasingly know how to trick.
