AI interviews promise to screen more candidates for less money. In practice they put off the best candidates, get sent to everyone, and produce results that few hiring managers are willing to act on.
Good candidates do not want to talk to a bot
The people you most want to hire usually already have a job. They have options, and they choose where to spend their time. If the first step in your process is a recorded conversation with an AI, many of them will close the tab.
Being interviewed by a machine tells a candidate that the company did not think they were worth a person's time. Strong candidates notice that. The ones who complete the interview are more often the ones with fewer options, so the tool can quietly shift your pipeline toward weaker applicants.
Free interviews get sent to everyone
When an interview costs a company nothing, there is no reason to be selective about who gets one. So companies send an AI interview to every applicant. A candidate who applies to twenty roles gets twenty interview invitations, and each one takes real time.
Candidates respond the way anyone would. They stop doing them. The interview then filters for patience, not for skill.
Would you trust an AI with the decision?
Say a candidate does finish the interview, and the AI scores them low. They are dropped. Would you ever find out if that was a mistake? Hiring managers rarely check rejected candidates, and a rejected candidate does not come back. Losing one strong engineer this way costs more than the tool saves.
AI models also make confident errors. They can miss the context behind an answer, or reward someone who sounds polished but says little. Candidates are now using AI to answer AI interviews, which weakens the signal further.
If AI could judge the work, it could do the work
Judging whether someone is good at a job takes knowing the job well. You need to know which follow-up question to ask, and to notice when an answer sounds right but is not. If an AI could do that reliably, it could do most of the job itself, and you would not need to hire. The technology is not there.
Where AI does help
AI is useful behind the scenes. It can transcribe an interview, pull out what a candidate showed, and make that easy to search and compare. That is how we use it at The Qualidex. People run the interviews, either the hiring company's own team or our interviewers. AI turns what was said into a record the candidate keeps and employers can read.
