AI Interviewer Tech vs Interviews by AI: Full Mock Interviews or Single-Question Drills?

AI Interviewer Tech vs Interviews by AI: the short answer

Both are AI mock interview tools, and both work for any role. The difference is the unit of practice.

• AI Interviewer Tech starts from your resume and runs a full interview — intro, then questions about the role and the experience in your CV — scores every answer against its own criteria and gives you a passed or failed result. It is free, with up to 5 interviews a day.
• Interviews by AI starts from a job description and works one question at a time. You answer out loud or in writing and get feedback built on frameworks like STAR, plus a stronger sample answer. The free plan gives you 3 questions a month; Pro is $9/month for unlimited questions and resume upload.

Use Interviews by AI to polish individual answers. Use AI Interviewer Tech to find out whether you would get through the whole interview.

Side-by-side comparison

Resume-first vs job-description-first: why it matters

The two tools make opposite bets about where interview questions come from.

Interviews by AI builds questions from the job description. That gets you what the employer says it wants: the skills, responsibilities and competencies in the posting. It is a good way to rehearse the "tell me about a time you…" questions a hiring manager writes from the JD. On the free plan the questions know nothing about you; resume upload is a Pro feature.

AI Interviewer Tech builds the interview from your resume, with the target position and JD as optional extras that make it sharper. That mirrors the other half of a real interview — the part where the interviewer has your CV open and asks about what you wrote. If your resume says you cut onboarding time in half or led a warehouse migration, a real interviewer will ask how. So will the AI.

In practice most interview rounds mix both: role questions from the JD, and probing questions from your CV. Candidates tend to over-prepare the first and get caught out by the second, because it is harder to predict what someone will pick out of your own history.

How AI Interviewer Tech works

1. Upload your resume. PDF or DOCX, maximum 10MB, written in English.
2. Add the target position and job description (optional). Skipping them still works; adding them lets the AI analyze more deeply and tailor the questions more closely.
3. The AI builds a realistic interview. It analyzes your CV and constructs a session that runs from an intro through theory and practical questions about the role and your actual experience.
4. Answer in English. Any field works — sales, finance, marketing, operations, engineering — as long as the interview is in English.
5. Get scored. Each answer is graded against criteria specific to that question, the scores are totalled, and you get a passed or failed result.

Limits: 5 interviews per day. Using inappropriate language triggers an immediate ban — the rate limit is set to 5, so no further interviews can be started.

How Interviews by AI works

1. Paste a job description, or pick one of the preset roles (Software Engineer, Business Analyst, Product Manager, Marketing Specialist, Data Analyst, UX/UI Designer, QA Engineer and others).
2. Get a realistic question generated for that role.
3. Answer out loud or in writing. Pro users get longer response times.
4. Read the feedback. It is built on frameworks like STAR and comes with a stronger sample answer to learn from.

The product was built by Jake Rosenthal and Chloe Pappas and says it is trusted by 50,000+ job seekers. On privacy, the site states that audio recordings are deleted immediately after transcription; if you log in, your interview history is saved so you can revisit it.

Is Interviews by AI free? Limits and pricing compared

The free tiers are not in the same league. Interviews by AI's free plan is 3 questions a month — enough to try the feedback, not enough to prepare for an interview. AI Interviewer Tech's free limit is 5 complete interviews a day.

Interviews by AI Pro is cheap at $9/month and can be cancelled any time from your account page; you keep access until the end of the period you have paid for. If you like question-by-question drilling with a sample answer after each one, it is fair value. Just note that the resume-aware version of the product is the paid one.

Feedback: STAR coaching vs pass/fail scoring

The feedback styles answer different questions.

Interviews by AI answers "how do I make this answer better?" STAR-based feedback (Situation, Task, Action, Result) checks whether your story has structure and a measurable outcome, and the sample answer shows you a stronger version. That is useful for behavioral questions, where a rambling answer with no result is the most common failure.

AI Interviewer Tech answers "would I pass this interview?" Every question has its own scoring criteria, the scores add up to a total, and the total becomes passed or failed. One strong answer does not rescue three weak ones, which is much closer to how a real interview is judged.

A good sequence uses both ideas: run a full scored interview to find which questions sink you, then drill those specific answer types until they hold up.

What you get after a failed interview

If you fail on AI Interviewer Tech, you can run Analyze with LLM, which uses today's strongest large language models to build your preparation for the next attempt:

The site also offers roadmap resources for hundreds of positions, for when the gap is knowledge rather than delivery.

Interviews by AI does not have a pass/fail stage, so there is no equivalent "after you fail" package. What it keeps is your interview history in the dashboard, so you can revisit past questions and feedback.

Where each one falls short

AI Interviewer Tech

• English only. Your CV and the interview must both be in English.
• No technical round. No coding test or technical interview for IT roles yet.
• 5 interviews per day. Plenty for serious practice, but it is a hard cap.
• Zero tolerance for abusive language. It ends your sessions immediately.

Interviews by AI

• Tiny free tier. 3 questions a month.
• Resume awareness is paid. Free questions come from the JD only, so they cannot probe your own experience.
• Question-level, not interview-level. You improve individual answers, but you do not get a verdict on a full interview.
• Limited answer time on free. Longer response times are a Pro feature.

Which one should you use?

The practical order: run a full, resume-based mock interview on AI Interviewer Tech with the job description attached, see which answers lost points, and fix them with the study schedule and question ebook. If you want extra reps on individual behavioral answers, a few questions on Interviews by AI is a good complement.
