Interviewing.io Alternatives: Are Cheaper Mock Interviews Good?
Yes, cheaper mocks are good for most of your practice, as long as you save a paid expert session for the end. Free options include Aced's peer mock interviews and interviewing.io's own free AI Interviewer for coding and system design; Hello Interview bundles live practice into paid plans. For the behavioral round, an AI speaking partner is enough. What only a senior human gives is calibration: whether you'd pass at your target level.
What you'd be giving up
As of October 2026, interviewing.io offers anonymous mock interviews with engineers it describes as coming from Meta, Google, OpenAI, Amazon and other large companies. Types include algorithms, system design, machine learning, front-end, engineering management and behavioral. Sessions use a shared coding environment with audio, no video, and end with written feedback. Its FAQ says interviews start at $179, vary by subject and whether you want a specific company's interviewer, and that you get a full refund if you're unhappy.
That's real value: someone who has made hiring decisions at your target level telling you whether you'd pass. But at that price, few people can afford ten. The good news: you don't need ten. You need many cheap repetitions and one or two expensive calibrations.
We make Speaking Coach, which appears below for the behavioral round only. It does not do coding or system design.

Are cheaper mocks actually good?
For most of your preparation, yes. Here's what each level really buys you.
Free peer mocks give you the pressure of a person watching you code, and they teach you by making you the interviewer half the time. The weakness is calibration: your peer may not know what a strong answer looks like at your level.
Free AI interviewers give you unlimited repetitions at 11 p.m. They're good for fluency: talking while you code, explaining complexity, structuring a design. They're weaker at the human judgment calls.
A paid senior human gives you the one thing the others can't: "At my company, this would be a lean hire," and why. That's worth paying for once you've fixed everything a free tool can catch.
What only a human interviewer gives
- Level calibration. Whether your system design is senior enough, not just correct.
- Real-time judgment on hints. Knowing when to nudge you, the way a real interviewer would.
- Company-specific norms. How a particular company weighs speed, communication or edge cases.
- Credible feedback on your story. Whether your "led a migration" sounds like leadership to someone who has promoted people.
Where AI speaking practice fits
The behavioral round can tip the decision between two similar technical candidates, and it's the cheapest one to practice. You don't need a staff engineer to tell you that your conflict story runs four minutes or that you said "basically" eleven times.
Two ways to cover it:
- Huru is free and asks follow-ups in a live AI interview.
- Speaking Coach (ours) plays an interviewer who has read your CV and the job post, asks about your actual projects, and follows up on what you said. It shows your pace, filler words, long pauses and how fast you started, with tips that quote your words, and lets you retry a fumbled moment for 90 seconds.
Prepare three to five stories first: a technical decision, a conflict, a mistake, a time you helped someone grow. See behavioral interviews and our software engineer question list.
A budget plan for a four-week search
- Weeks 1 to 2: Free AI and peer mocks for coding, three to four a week. Two behavioral practice sessions a week.
- Week 3: One system design mock with a peer or a plan that includes live practice. Keep behavioral reps going.
- Week 4: One paid expert mock in your weakest area. Spend the rest of the week fixing what it found.
Questions people ask
How much does interviewing.io cost?
Its FAQ says interviews start at $179, with the price depending on the subject and whether you want an interviewer from a specific company, as of October 2026.
Is there a free version of interviewing.io?
Its free AI Interviewer runs coding and system design interviews, per its FAQ, and its home page lists free access to problems and sample book chapters. Human mocks are paid.
Are peer mock interviews worth it?
Yes, for repetitions and pressure. Their weak point is calibration, so pair them with one expert session near the end.
Can AI replace a human mock interview?
Not fully. AI is great for frequency and for spotting delivery problems. A senior human is better at judging whether your answer would pass at a specific level and company.
What's the cheapest way to practice the behavioral round?
Write three to five stories, then say them out loud with something that asks follow-ups: a friend, Huru (free) or Speaking Coach.
