Static Q-lists tell you what was asked. PhantomCode lets you DRILL — voice-paced, graded, with weak-area diagnostics. Coding, behavioral, system design. Same coach in prep and live mode.
45-minute mocks, 15-minute behavioral rounds, sub-30-minute DSA sprints. Set the format, the generator picks role-appropriate questions, the coach grades you.
Most practice sites compare your code to a reference solution. PhantomCode grades correctness AND explanation, structure, and time-per-step. The grading mirrors what FAANG interviewers actually do.
After 10-15 drills the coach tells you exactly where you're losing points — sliding window, DP-on-trees, behavioral conciseness — and serves drills that close those gaps.
L3 to L7 SDE. PM, sales, finance, design. The bank narrows to what your level actually gets asked — not generic 'top 50' lists.
Reading flashcards isn't practice. Talking your way through a problem is. The coach hears your explanation and grades it for clarity, not just correctness.
The mock coach IS the live coach. Drills in prep mode build the muscle memory that fires automatically when the real interview happens.
Browsing question lists is comfort, not preparation. The candidates who get FAANG offers drill — voice-paced, timed, with feedback on every attempt.

Each company hub has role-tier-specific drills and 20+ representative question sets.
Drill voice-paced (the real interview is voice), timed (the real interview is timed), and with feedback on structure and communication, not just correctness. Static lists are comfort food; drills with grading are preparation.
Quality over count. For a 30-day FAANG-prep window, ~60-90 coding problems is the right range, but only if you're drilling with explanation, not solving silently. See the FAANG 30-day roadmap for the breakdown.
Yes. PhantomCode grades behavioral STAR stories on length (most fail by being too long), specificity (most fail by being too vague), and impact-statement clarity. The coach also asks the follow-ups that real interviewers ask.
If you're targeting L4+ SDE, yes. The follow-up tradeoffs are where candidates get caught. PhantomCode simulates an adversarial senior interviewer poking at your design.
Drilling is necessary but not sufficient. You also need realistic mock interviews (PhantomCode mock mode) and ideally one or two live coaching sessions with the same AI running, so your prep transfers exactly to the real round.
Run a 45-minute timed mock interview with role-appropriate questions and live feedback — same coach that runs in your real interview.
