Phantom Code vs Interviewing.io

Interviewing.io is for practice. Phantom Code is for performance during actual interviews. When the real interview starts, practice alone isn't enough — you need real-time assistance.

Phantom Code helps during actual interviews. Interviewing.io is practice only — when the real interview starts, you're on your own.

90%+ Cost Savings

One year of Phantom Code costs less than two Interviewing.io sessions at $225+ each. At $49/month, you get unlimited real-time assistance.

Zero Detection Cases

20+ stealth features. Invisible in screen share, Activity Monitor, dock, and system tray. Native desktop architecture avoids all detection vectors.

Why Developers Switch from Interviewing.io

Practice vs Performance

Interviewing.io gives you mock interviews for practice. But when the real interview comes, you're alone. Phantom Code is your real-time copilot during the actual interview — generating solutions, analyzing problems, and providing hints while you talk.

Extreme Cost Difference

Interviewing.io charges $225+ per session with a human interviewer. Two sessions cost more than an entire year of Phantom Code at $49/month. The math speaks for itself.

Availability & Access

Interviewing.io sessions need to be scheduled and depend on interviewer availability. Phantom Code is available 24/7, instant, and works during any interview — no scheduling, no waiting.

Complete Technical Coverage

Phantom Code covers DSA, system design (HLD + LLD), SQL, behavioral, and OA rounds — all with AI-generated solutions. Interviewing.io is limited to practice-only sessions with human feedback.

Stop Practicing. Start Passing.

Practice is important, but performance matters more. Get real-time AI assistance during actual interviews at a fraction of the cost.

Frequently Asked Questions

Is Phantom Code a replacement for Interviewing.io?: Not exactly — they serve different stages. Interviewing.io provides human mock interviews for practice in the weeks before your real interviews. Phantom Code provides AI assistance during the actual live coding round. Many candidates use Interviewing.io for prep and Phantom Code on the real day.
Why does a single Interviewing.io session cost as much as a year of Phantom Code?: Interviewing.io pays human engineers per session — that's the cost driver, plus a marketplace margin. Phantom Code amortizes a single AI engine across thousands of users, so per-user pricing is much lower. $199/year of Phantom Code covers roughly the same dollar value as one Interviewing.io session.
Can Interviewing.io detect Phantom Code during a mock?: If you somehow used Phantom Code during an Interviewing.io mock, the human interviewer would not see the overlay (OS-level capture exclusion applies regardless of who's on the other end). However, using AI assistance during a paid practice session defeats the point — practice sessions exist for you to find weaknesses to fix, not to simulate the assisted state.
What if I only have a one-week interview window?: Interviewing.io requires booking sessions days in advance and the value is in spaced practice. For a one-week window, the higher-ROI move is install Phantom Code (under 2 minutes), do 1-2 self-recorded mock rounds to get comfortable with the overlay, and use it on the real interview day.
