AI Interviewer Tech vs interviewing.io: the short answer
These two tools serve different candidates at very different price points.
- AI Interviewer Tech is a free AI interviewer for any field. Upload your resume, and it runs a full interview built from your CV and target role, scores every answer against its own criteria and returns passed or failed. It runs in English and does not include coding rounds.
- interviewing.io is built for software engineers. Its core product is anonymous mock interviews with senior engineers who have interviewed at FAANG and other top companies — coding, system design, machine learning, behavioral and more — starting at $179 per interview. It also offers a free AI interviewer for FAANG-style coding and system-design practice.
If you are an engineer preparing for a big-tech technical loop and can pay for expert feedback, interviewing.io is the specialist. If you are interviewing in any other field, or you want repeatable, resume-based practice that costs nothing, use AI Interviewer Tech.
Disclosure: AI Interviewer Tech is built by the Netalith team. Both tools' limitations are listed below.

What interviewing.io actually offers
Paid mock interviews with senior engineers
interviewing.io's main product is anonymous practice with experienced engineers. According to its FAQ, interviewers must work at FAANG or similar companies, have at least 4 years of experience (the average is over 8), have conducted at least 20 interviews on behalf of a FAANG or FAANG-adjacent company, and pass two trial interviews. Listed employers include Google, Meta, Amazon, Microsoft, Uber, OpenAI, Netflix and Stripe.
Sessions are fully anonymous — voice and chat, no video — and your interviewer does not get your personal information. You can reveal who you are afterwards if you want. The site reports 100K mock interviews hosted and 10K engineers helped. Prices start at $179 and depend on the subject and on whether you book an interviewer from a specific company; the FAQ promises a full refund if you are unhappy.
A free AI interviewer for coding and system design
interviewing.io also runs a free AI Interviewer that simulates a FAANG-style interview and covers both coding and system design, with 200+ problems from Beyond Cracking the Coding Interview.
So the fair comparison is not "free vs $179" across the board. For technical practice, interviewing.io has a free AI option too. The difference is focus: interviewing.io's AI is built for engineering problems; AI Interviewer Tech is built around your resume and the role, for any field.
How AI Interviewer Tech works
- Upload your resume. PDF or DOCX, maximum 10MB, in English.
- Add the target position and job description (optional). With them, the AI analyzes more deeply and tailors the interview more closely.
- The AI builds a realistic interview. Intro first, then theory and practical questions about the role and the real experience in your CV.
- Answer in English. Any field works — sales, finance, marketing, operations, healthcare admin, engineering.
- Get scored. Each answer is graded against criteria specific to that question, the scores are totalled, and you get passed or failed.
Limits: up to 5 interviews per day. Inappropriate language triggers an immediate ban — the rate limit is set to 5, so no further interviews can be started.
Anonymous technical mocks vs resume-based interviews
The two tools take opposite positions on your resume, and each is right for its purpose.
interviewing.io hides it. Anonymity lets you practice without your background shaping how you are judged, and for algorithm and system-design rounds your resume barely matters — the problem on the screen does.
AI Interviewer Tech is built on it. In most interviews outside pure technical rounds — and in the behavioral and "walk me through your experience" parts of engineering loops too — the interviewer has your CV open and asks about it. Why did you make that decision? What was the result? What would you do differently? AI Interviewer Tech reads your CV and asks exactly those questions, then adds the target position and JD if you provide them.
That makes them complementary for engineers: technical rounds on interviewing.io, the experience and role conversation on AI Interviewer Tech.
Feedback: expert rundown vs criteria-based verdict
A paid interviewing.io session ends with an in-depth rundown from someone who has run real interviews at top companies: what you did well and how to improve, plus a replay. That is the closest thing to a real interviewer's judgment you can buy.
AI Interviewer Tech gives you something different: a consistent benchmark. Every answer is scored against the same per-question criteria, the scores add up to a total, and the total becomes passed or failed. You can run it again the next day and compare like for like — which is hard to do across different human interviewers.
What you get after a failed interview
On AI Interviewer Tech, a failed interview unlocks Analyze with LLM, which uses today's strongest large language models to prepare your next attempt:
| Output | What it contains | Built from |
|---|---|---|
| Study schedule | A preparation plan for your next interview | Your target role, JD and CV |
| Question ebook (PDF) | 50–100 questions of different types — the equivalent of 3 to 6 real interviews | Your target position, JD and CV, plus a bank of 200,000+ questions collected from 10,000+ real interviews |
| Guideline ebook | Interview guidance from an author who has interviewed at leading tech companies including Samsung, FPT and Google | First-hand interview experience |
The site also offers roadmap resources for hundreds of positions.
On interviewing.io, the follow-up to a weak paid session is the interviewer's feedback, the replay, and your next booking.
Where each one falls short
AI Interviewer Tech
- English only — both the CV and the interview.
- No coding test or technical interview for IT roles yet. For algorithm and system-design practice, interviewing.io is the better tool.
- 5 interviews per day, with a zero-tolerance ban for inappropriate language.
- No human judgment — no experienced interviewer reading between the lines.
interviewing.io
- Engineers only, in practice. Interview types are engineering and engineering-management focused.
- Expensive at volume. From $179 per human mock; several sessions add up quickly.
- Not resume-based. Anonymity is a feature for technical rounds, but it means no practice defending your own history.
- No video. Fine for technical rounds, less useful if on-camera presence is what you need to practice.
interviewing.io alternative or complement? Which to use
| Your situation | Better fit |
|---|---|
| FAANG-style coding or system-design loop, and budget for expert feedback | interviewing.io (paid mocks) |
| Free coding and system-design practice | interviewing.io's free AI Interviewer |
| Any non-engineering role | AI Interviewer Tech |
| You expect questions about your own resume | AI Interviewer Tech |
| You want a pass/fail benchmark you can repeat | AI Interviewer Tech |

| Budget is zero and you need several practice rounds | AI Interviewer Tech |
For software engineers, the efficient split is: technical rounds with interviewing.io, and the intro, role and experience conversation with AI Interviewer Tech — free, built from your CV, with a clear verdict. For everyone outside engineering, AI Interviewer Tech is the one of the two built for you.
