What is Interview Solver?
Interview Solver is an AI interview copilot for coding interviews: an invisible desktop application that provides real-time answers to LeetCode-style problems and system design questions while the candidate shares their screen. The product's core promise is being undetectable: the app is invisible to screensharing, invisible in Activity Monitor, and supports transparency, so users can view answers without raising suspicion during proctored or remote interviews. Key features include Invisible Mode for screensharing, a screengrab tool that sends the contents of any window to the AI for one-shot solutions, voice transcription that captures both the candidate's and interviewer's speech, undetectable global hotkeys that avoid alt-tabbing, document upload so users can reference resumes and technical materials, and Companion mode which turns any device into a second screen that can remote-control screenshots, voice, and prompts, useful when HackerRank's tooling logs hotkeys on the main machine. The app also renders flowcharts and full syntax highlighting for solutions. Interview Solver positions itself as the leading AI interview copilot and claims to be trusted by 10,692+ engineers, with testimonials reporting offers from Microsoft, Google, Amazon, and other top companies. The site includes salary comparison data for senior software engineering roles at major employers, free tools such as an ATS resume checker, STAR method builder, salary lookup, and Big O cheat sheet, plus comparison pages against competitors like Final Round AI, UltraCode, Interview Coder, and LockedIn AI. Pricing is simple: a free trial limited to 10 messages and a Monthly plan at $39 per month, with a Discord community and an affiliate program. The company is Interview Solver, Inc., and support is available at hello@interviewsolver.com. The product also includes comparison pages against competing interview copilots, free tools for resume checking and salary research, and company-specific interview question libraries. Interview Solver's positioning focuses on out-performing every candidate in the room, and the marketing emphasizes both capability and discretion. The desktop application is complemented by a web-based companion at interviewsolver.com/web, and the help center documents usage patterns for different interview formats. With more than ten thousand engineers reportedly using the product and a community on Discord, it has become one of the more established tools in the interview copilot category.

Who is Interview Solver for?
Interview Solver is built for software engineers preparing for or taking technical interviews. Job seekers interviewing at big tech companies such as Google, Amazon, Microsoft, Meta, and Netflix use it to answer LeetCode problems and system design questions in real time. Bootcamp graduates and career switchers use it to compete with CS-degree candidates during phone screens and onsite loops. Software engineers re-entering the job market after layoffs use it to overcome rustiness on algorithms they have not practiced in years. Product managers and non-coding roles use it for system design and behavioral segments where technical answers are needed. Candidates facing proctored assessments, including HackerRank-style tests, use Companion mode and invisible hotkeys to reduce detection risk on monitored machines. Finally, international candidates who benefit from voice transcription of interview questions use it to understand and answer questions accurately, and the free trial lets any candidate evaluate the product before paying. Candidates facing take-home assessments with screen recording use the app's transparency and invisibility features to review solutions without interrupting their flow. Non-traditional candidates without computer science degrees use Interview Solver to level the playing field on algorithm rounds they have not formally studied. Senior engineers interviewing for staff and principal roles use system design assistance to structure large-scale architecture answers. Contractors and freelancers taking technical screens for client projects use it to pass assessments efficiently. Career coaches and bootcamp instructors recommend the tool to students preparing for job placement interviews. Candidates interviewing across multiple companies in parallel use the document upload to keep each company's context and requirements organized during interviews. Finally, international candidates interviewing in English use voice transcription to catch and answer questions accurately in real time.
