AI Interview Guide
What is an AI interview?
Interview workloads that swell with every new applicant, evaluation criteria that differ from one interviewer to the next, days spent chasing schedule adjustments. As a way to solve these challenges on the hiring frontline, the AI interview is now drawing attention.
An AI interview is a hiring method that uses artificial intelligence to automate the first-round interview. Candidates answer the questions presented by the AI on video from their smartphone or PC. The AI analyzes those responses and provides an evaluation report to the HR team.
The role and position of the AI interview
AI interviews are mainly used in the first-round selection (screening). Positioned between document screening and the final interview, they play the role of efficiently checking an applicant's basic communication skills and motivation.
Important: An AI interview is not a substitute for the final interview. The final judgment on personality and cultural fit is always made by a human. AI is a tool specialized for making screening more efficient.

The benefits of adopting AI interviews
Greatly reduce interviewer workload
By leaving the first-round interview to AI, interviewers can focus on important tasks such as the final interview. Even with 100 applicants, the interviewer's committed time is zero.
Unified evaluation criteria
Because AI evaluates every candidate by the same criteria, variation in evaluation between interviewers disappears. Fair and consistent selection becomes possible.
Faster selection
Because no schedule adjustment is needed, the lead time from application to completed selection is greatly shortened. You can secure excellent talent before other companies take them.
A better candidate experience
Candidates can take the interview at a time that suits them. It enables a selection process that also considers people who are job hunting while working.
Cautions and limits of AI interviews
AI interviews are not all-powerful. When considering adoption, it is important to understand the following points.
The final judgment is made by a human
An AI interview is a screening tool. Judgments such as personality, cultural fit, and compatibility with the team must always be confirmed in person by an HR representative or a frontline manager.
Question design matters
The accuracy of an AI interview depends heavily on the quality of the questions you set. Designing appropriate questions for the job type and role makes for a more effective selection.
It is not suited to every job type
For positions that require advanced expertise, or roles where interpersonal skills are extremely important, an AI interview alone may not provide a sufficient evaluation.
Cases where AI interviews are especially effective
For companies facing the following hiring challenges, the benefit of adopting AI interviews is especially high.
Companies that hire in large volume
It is especially effective in hiring activities with many applicants, such as new-graduate hiring and part-time hiring.
Companies with few recruiters
Even small and mid-sized companies with limited HR resources can carry out an efficient selection process by using AI interviews.
Hiring from remote areas or overseas
It is ideal for selecting candidates who are physically distant, such as hiring at regional bases or hiring foreign-national talent.
Frequently asked questions
Yes. Because an AI interview evaluates all candidates under the same conditions based on criteria set in advance, it is less prone to the subjective bias of an interviewer. That said, the design of the evaluation criteria itself is important, and setting fair criteria makes a more accurate selection possible.
With many AI interview services, everything from creating an account to setting up questions is completed in a few hours to about a day. With ZeroInterview AI, question templates are also provided, so it is possible to start interviews on the same day at the earliest.
Some candidates find it unfamiliar at first, but once they experience benefits such as being able to take it at a convenient time and showing their ability without nerves, it is often received favorably. Younger candidates in particular tend to have little resistance to expressing themselves on video.
It is broadly suited to jobs where you want to check basic communication skills and motivation, such as sales, customer service, administrative work, and engineers (junior to mid-level). On the other hand, for positions that need deep dialogue, such as executives and highly specialized professionals, we recommend limiting the AI interview to first-round screening and conducting a human interview at an early stage.
Trustworthy AI interview services take strict security measures, such as data encryption, access restrictions, and automatic deletion after a set period. When choosing a service, we recommend checking its privacy policy and whether it holds security certifications.
