interviewing.io offers mock technical interviews with practicing engineers, so you can rehearse the real thing with a person who has run interviews at large tech companies. This guide explains how it works, who it suits, what to compare it with, and how to get the most from any mock interview. Details were taken from interviewing.io's own site in October 2026. Pricing wasn't published on the page we checked, so look at the current site before you decide.
What interviewing.io offers
According to its site, it provides mock interviews across several areas: algorithms and data structures, coding, system design, machine learning, front-end engineering, engineering management, and behavioral practice, plus staff-level and manager practice interviews.
How the sessions work, from the site:
- Sessions are anonymous. You talk by audio and chat, with no video, in a shared coding editor (CoderPad).
- After the session, you can choose to unmask and connect with the interviewer.
- Interviewers are described as senior, staff, or principal-level engineers or managers who make hiring decisions at large tech companies, including firms such as Google, Meta, Amazon, Microsoft, Netflix, and Stripe.
- You get written feedback on what went well and what to improve from the engineer who ran your session.
- There's a free AI interviewer, where you can work on over 200 problems from the book Beyond Cracking the Coding Interview.
Who it suits
| You are | Fit |
|---|---|
| Preparing for big-tech coding interviews and want realistic pressure | Good: a human interviewer who has hired in that setting |
| Unsure how you come across when you explain your approach | Good: the feedback covers communication as well as code |
| Short on money and time | Check the price first. Free practice can cover a lot of the early work |
| Weak on the basics | Start with solo practice or a study plan before paying for expert time |
| Targeting a specific non-tech role | Look for a service that offers your type of interview |
How to use a mock interview well
- Be ready first. Do your solo practice until you can solve medium problems in 30 to 40 minutes. Expert time is best used on communication and polish, not basics.
- Treat it as the real thing: same setup, no notes you wouldn't have, a timer.
- Talk aloud from the start. Clarify the problem, state the brute force, and say your plan before you code.
- Ask for feedback on specific things, such as how you handled hints, how clearly you explained complexity, and whether you tested your code.
- Write down every piece of feedback within an hour, and turn each into a practice task.
- Do two or three sessions spaced a week apart, so you can see improvement.
What to compare it with
| Option | What it is | Good for | Watch for |
|---|---|---|---|
| Peer mock interviews | Practicing with a friend or on a peer platform | Free and flexible | Quality varies with your partner |
| Paid expert mocks | A human expert gives feedback | Realism and feedback | Cost, scheduling |
| AI mock interviews | An AI asks questions and responds | Cheap, available any time, good for volume | Less human pressure; feedback can be generic |
| Solo timed practice | You solve problems against the clock | Free, builds speed | No communication feedback |
| Practice tools with transcripts | Record your session and review it | Cheap, builds self-awareness | You need to review honestly |
A combined approach often works best: solo practice for the patterns, AI or peer mocks for volume, and one or two paid expert sessions close to the real interviews.
Practicing with YesToTheOffer
We make YesToTheOffer, so weigh this accordingly. It's an interview assistant for macOS and Windows with a web app. It doesn't have a mock interview mode where an AI plays the interviewer, so it isn't a substitute for the practice platforms above. What it does keep is a transcript and a review after each session, which shows where you rambled or skipped complexity. Pricing is per minute with no subscription: $29.99 buys 240 minutes, $59.99 buys 600, and $99.99 buys 1,200, and new accounts get 30 free minutes. See our guide on mock interviews versus real-time assistants.
Making the most of any practice platform
- Use the same language and editor you'll use in the interview.
- Practice in a plain editor, not an IDE with autocomplete, if the real interview uses a simple editor. Our CoderPad sandbox guide shows a free way to do that.
- Practice stating your approach before coding, and finish by testing with examples.
- Don't only do the problems you like. Do the weak patterns on purpose.
Questions to ask before you pay
- What is the current price per session or plan, and what's refundable?
- How are interviewers chosen, and can I ask for a type of interview, such as system design?
- Do I get a recording or only written feedback?
- How soon after the session do I get feedback?
- Is there a free tier I can try first?
