What you get
You choose a target company, a round and your experience level, then talk through the problem with its AI interviewer. Its FAQ says coding and behavioral sessions run 30 minutes and system design 45. The coding editor runs Python, Java, C++, JavaScript, C#, Scala and Go; system design uses a whiteboard canvas; behavioral rounds follow the STAR format.
Each session ends with a scored evaluation out of 5: communication, problem solving, code quality and language proficiency in its coding example, with a hire verdict and what to fix, compared with your last session. It also sells 23 interactive courses and 115 lessons, and says its question bank holds 2,000+ free questions from 600+ companies. Those are its own figures. We read its pages for this comparison and did not test a paid plan.

DevInterview.AI vs Devana
These two are the closest match here: both are spoken AI interviews with code that runs. They differ on price model, on what you can practice from, and on how the score is shown.

When DevInterview.AI is the better choice
- You want the most interviews for the least money. At $99.99 a year for unlimited sessions, it costs far less than Devana's yearly Pro at $348, which is capped at 40 interviews a month.
- You code in C#, Scala or Go. Its editor runs all three. Devana's does not.
- You want courses and interviews on one subscription. Its plans include all 23 courses. Devana has free written guides but no courses.
- Your target company is outside Devana's sets. It says it has problems from 600+ companies, against Devana's 46.
- You want one conversation with a person. The yearly plan includes a 30-minute call with a senior engineer. Devana has no human sessions.
When Devana is the better choice
- You want to try it properly for free. Devana's Free plan gives you 3 interviews every month with the full report, not one interview in total.
- You want to practice your own material. Paste any problem, or run a round built from your resume. DevInterview.AI's pages do not mention either.
- You want full-length rounds. A paid coding or system design round runs up to 60 minutes, closer to a real one than 30 or 45.
- You want to read the rubric. Devana publishes every metric and its points on each round's page, so you can see what a score measures before you start.
- You have a short search and no wish to subscribe. The Sprint Pass is $19 once for 14 interviews in 14 days, and nothing renews.
The other alternatives
- interviewing.io is for a read from a person. Sessions with senior engineers start at $179, and its FAQ promises a full refund if you are unhappy. Its AI Interviewer is free for coding and system design.
- Final Round AI is mainly a live copilot for real interviews. Practice is on its paid plans, runs in its desktop app and uses the resume and job description you attach to a goal.
- Aced is for practicing with people: peer mocks over video, 5 a month on its free Basic plan. Its AI mock interviews are on the Expert AI plan.
