On September 29, 2026, Interviewing.io's FAQ said "Interviews start at $179," with the price depending on the subject and on whether you want an interviewer from a specific company. Prices for its Amazon, Google, and Meta coaching packages (3, 5, or 10 sessions) and its salary negotiation service are not published on its site (checked September 29, 2026). Its AI Interviewer is free. OphyAI Pro is $29 a month and Premium is $59 a month.
Its human mock interviews are paid, but its AI Interviewer is free: on September 29, 2026, its FAQ said "It's free, it simulates a FAANG-style interview, and it can do both coding and system design," and its homepage said you can work over 200 problems from Beyond Cracking the Coding Interview for free. A company blog post from September 2022 said new users got 1 interview with a peer when they joined; its current homepage and FAQ do not mention peer practice. OphyAI's free plan includes one Interview Practice session capped at 15 minutes and, for eligible new users, a first Standard Interview Copilot session of up to 15 minutes, with no card.
On September 29, 2026, its FAQ said "If you're unhappy with your interview(s), we'll issue a full refund." Its Terms of Use (effective November 2, 2018) do not mention refunds, and its site does not publish a time limit or a request process. Its Terms and Privacy Policy give support@interviewing.io as the address to email it, so ask there before you book if the details matter to you.
It is built for them. Its homepage title is "Anonymous Coding & Technical Interview Prep for Software Engineers," and its FAQ says questions are similar to a real technical interview at a top company for a backend or full-stack role. Its homepage also lists machine learning, front-end, engineering management, behavioral, and staff-level mocks (checked September 29, 2026). OphyAI Interview Practice covers behavioral, technical, system design, and case interviews in voice or text, so it also fits candidates outside software engineering.
No such feature is listed on its site (checked September 29, 2026). Interviewing.io is for practice before interviews, plus coaching and salary negotiation. OphyAI Interview Copilot works during the interview on Zoom, Microsoft Teams, and Google Meet, showing a live transcript and streamed answer suggestions based on your resume and the job description. Suggestions can be wrong, so answer with your own true experience and follow the interviewer's rules.
Its FAQ says sessions have voice but no video, your interviewer cannot see your information, and it will not pair you with coworkers. Its public replay page says every recording there is shared with permission from both participants. Its Terms let it use interview content to run and improve the service and for academic research, which may include sharing aggregated or anonymized content. OphyAI's Whisper Mode is a private picture-in-picture overlay, but what others can see depends on what you share or record and on your browser, device, and meeting setup, so test your exact setup.
Its homepage says human mocks happen in its own version of CoderPad, with audio and chat but no video. The AI Interviewer is linked from its site at start.interviewing.io. On September 29, 2026, no Interviewing.io app turned up in a US App Store search, its site listed no desktop app, and it did not publish which spoken languages its interviews support. OphyAI runs in the browser with no install required, and Interview Copilot works with Zoom, Microsoft Teams, and Google Meet in 35 languages.
It depends on what you need. Choose Interviewing.io if you want a senior engineer from a FAANG-type company to run a realistic technical mock and are fine paying from $179 per session. Choose OphyAI if you want to practice often for $29 a month, prepare for case interviews or a role outside software engineering, get live help during the real interview, and keep resume and application tools in one account. You can also combine them: use AI practice for frequent reps and save a paid human mock for a final check before a big loop.
Start with a free Interview Practice session of up to 15 minutes and, if eligible, a first Interview Copilot session of up to 15 minutes, with no card. Then compare Pro at $29 a month with Interviewing.io's human mocks from $179 each.
