What You Gain With Interview Coder
Solve Interview Problems Instantly
Stop guessing during high-pressure interviews and get an initial solution you can iterate on immediately. That means less wasted time on incorrect directions and more time validating and optimizing the right approach.
Cut Prep Time Dramatically
Instead of grinding hundreds of problems for months, use targeted practice plus live rescue during real interviews. The result is faster path to interviews that end in offers rather than endless prep cycles.
Lower Cost Higher ROI
Pay $25 per month annually and keep access for years at the cost of a single Formation.dev month. This lets you allocate cash to living expenses or smarter career investments while still getting interview results.
Confidence And Calm Under Pressure
You stay focused on communication and reasoning while the AI assists with coding and edge cases. The outcome is clearer explanations, fewer panicked pauses, and more confident performance.
Undetectable By Design And Built For Every Interview Platform
Full workflow to get Interview Coder up and running securely
Native Desktop Invisibility
Interview Coder runs natively on your machine and avoids injected overlays that trigger recordings. That design keeps the tool invisible during screen share and recording so you can use assistance without creating detection flags.
Platform Compatibility
Works with Zoom, HackerRank, CodeSignal, CoderPad, Google Meet and other web-based interview tools. We maintain an up-to-date compatibility list and recommend simple checks so you know it will run on your interview platform.
Commands We Love
Natural commands like Hide Show Window, Capture Screenshot, Generate Solution and Reset Context let you control assistance without breaking flow. These commands were made to be easy to remember and fast to execute when you need them most.
Basic Checks And Troubleshooting
Confirm Zoom settings or use browser links when certain desktop apps misbehave, and check our basic checks page before an interview. Follow the quick troubleshooting steps so you avoid last-minute surprises and preserve the stealthy experience.

Compare The Math
Thousands per month or large one-time fees
Single low monthly fee when billed annually
Formation.dev often charges thousands per month or large one-time fees. Interview Coder costs $25 per month annually, which means a single Formation.dev month could pay for Interview Coder for 120 years, delivering immediate, measurable ROI.
Simple Plans
Free plan gives limited model access and restricted solution visibility so you can verify undetectability at no cost. Pro unlocks full models, complete solutions, and higher usage limits for a single low monthly fee when billed annually.
Referral And Savings
Earn 40 percent of referrals and reduce your net cost further. The referral program incentivizes early adopters and lowers long-term ownership expense while growing community validation.
Free Plan Caveats
The free plan does not include the latest models and hides full solutions to prevent abuse. Use it to validate undetectability and basic flows before upgrading to Pro for full capability.
