Frequently Asked Questions

How is Phantom Code cheaper than Interview Coder?: Phantom Code starts at $19 (Starter credit pack, one-time) versus Interview Coder's $60/month flat USD pricing — substantially lower entry. Phantom Code also offers credit packs up to $69 (one-time, no expiry) and a $399 lifetime plan that Interview Coder does not match.
What does Phantom Code's Deep Think mode do that Interview Coder doesn't?: Deep Think runs slower, more thorough reasoning suited for hard DSA and system design problems — it walks through tradeoffs, complexity, and edge cases before returning the optimal solution. Fast Think is the lower-latency mode for time-pressured live answers. Interview Coder offers a single response mode without this tradeoff control.
Can I use Phantom Code on the same platforms Interview Coder works on?: Yes. Both tools run on macOS and Windows, and both work on the major coding platforms (HackerRank, CodeSignal, CoderPad, LeetCode) plus video calls (Zoom, Google Meet, Microsoft Teams). The undetectability mechanism — OS-level screen-capture exclusion — is the same approach in both tools.
Does Phantom Code support SQL and database design?: Yes. Phantom Code has first-class SQL support — complex queries, query plan reasoning, schema design, and normalization questions. Interview Coder is DSA-focused and does not have dedicated SQL coverage. If you're interviewing for backend, data engineering, or analytics engineering roles, this is a meaningful difference.
Is the migration from Interview Coder to Phantom Code straightforward?: Yes — install Phantom Code (under 2 minutes), pick your AI mode and language preference, and you're set. There's no data to migrate since interview-prep tools don't store interview history persistently. Test undetectability in a self-recorded Zoom call before your first real interview to confirm the overlay is invisible.
