What it is
A native desktop application for macOS and Windows, built around software engineering interviews rather than general meetings. It is a desktop app rather than a browser extension, which matters for assessment platforms that scrutinise the browser.
What it does
Real-time code generation for LeetCode-style problems, plus system design assistance, which is broader than the pure coding copilots it competes with. It transcribes both the interviewer's and your own audio, and you can upload your resume and the job description so answers have context.
Its most distinctive feature is companion mode, which lets you control the session remotely from a second device. As with any second-device setup, rehearse it before you rely on it: moving attention between screens is noticeable if you have not practised making it look natural.
What it costs
Its pricing page publishes a free tier, a monthly plan and a three-month plan the vendor frames as an interview cycle. That three-month shape is thoughtful, because it matches how long a real search tends to run better than a rolling monthly subscription does.
We saw conflicting figures between the vendor's own page and third-party listings while researching, which is a good reason to take the number from the source and to confirm the renewal rate before subscribing.
What is not published
Interview Solver does not publish a list of supported meeting platforms, and it does not publish which AI models it uses or its response latency. For a coding-first tool, the model question matters more than usual, because models differ noticeably on code. Ask before buying if that is part of your decision.
Its homepage also cites a count of engineers served and carries customer testimonials. Those are vendor-supplied and unaudited, and we have not treated them as evidence.

Who it suits
- Engineers whose loop is mostly coding rounds with some system design.
- Candidates who want a desktop app rather than something running inside the browser.
- Anyone whose search will realistically run about three months, where the cycle plan fits better than monthly billing.
Who should look elsewhere
- Candidates with heavy behavioral or recruiter stages, which are not its focus.
- Anyone who needs a specific meeting platform confirmed in advance.
- People who care which model answers, since it does not publish that.
Alternatives worth comparing
Our comparison page is CoPilot Interview vs Interview Solver. For other coding-first options, see Interview Coder Review, LeetCode Wizard Review and ShadeCoder Review.
Disclosed alternative: CoPilot Interview covers coding, system design and behavioral rounds, publishes its model choice per question, and has a permanent free tier that includes live use.
Frequently asked questions
Is Interview Solver legit?
Yes, in the sense that matters: a real native desktop app for macOS and Windows, a published pricing page with a free tier, and a documented feature set including system design help and companion mode. The gaps are in disclosure, chiefly the absent meeting-platform list and no published information about models or latency.
Is Interview Solver free?
There is a free tier alongside a monthly plan and a three-month interview-cycle plan. Check what the free tier actually includes before planning an evaluation around it, and confirm the renewal terms of whichever paid plan you choose.
What is companion mode?
It lets you control the session remotely from a second device rather than the machine running the interview. It is a genuinely different setup shape, and the practical advice is to rehearse it in a mock round first, because glancing at another device is conspicuous if you have not practised it.
Does Interview Solver handle system design?
It publishes system design assistance alongside real-time code generation, which makes it broader than the pure coding copilots in this category. Test that specifically in a mock round, since a design round is a spoken conversation about trade-offs rather than a problem with one correct answer.
What does Interview Solver cost?
Its pricing page lists a free tier, a monthly plan and a three-month plan. We saw different figures quoted on third-party sites than on the vendor's own page, so take the number from interviewsolver.com directly and confirm the renewal rate before subscribing.
Which AI model does Interview Solver use?
The vendor does not publish this, nor its response latency. For a coding-focused tool that is a meaningful omission, because models differ noticeably on code quality. Ask the vendor directly if it affects your decision.
