45-minute timed coding rounds. AI grades correctness, explanation quality, and time-per-step — not just whether your code passes. Same coach that runs in your real coding interview. 11 programming languages.
Real FAANG coding rounds are 45 minutes for 2 problems. The mock format mirrors this — same timer, same pacing pressure, same recovery dynamics if you slow down on problem 1.
Strong coding rounds win on explanation, not just code. The coach hears you narrate your approach, grades clarity, and flags when you go silent mid-problem.
Tracks how fast you identify the underlying pattern (sliding window, DP, BFS, etc.). Fast pattern recognition is the single highest-leverage coding interview skill.
Python, JavaScript, TypeScript, Java, C++, C#, Go, Rust, Swift, Kotlin, Ruby. Idiomatic code grading — uses the right standard-library calls and naming conventions for your chosen language.
Most candidates lose points by missing edge cases. The coach grades whether you list edge cases BEFORE coding, which is what interviewers notice.
Practice with PhantomCode in mock mode; the same model runs live during your real interview. The patterns you internalize transfer directly.
LeetCode gives you problems and lets you solve them silently. A mock coding interview adds: time pressure (45-min rounds), voice explanation grading, pattern recognition timing, and edge-case discipline scoring. These are the things FAANG interviewers actually evaluate — they don't show up when you solve problems in isolation.
Aim for 10+ full voice-paced timed mocks before the real round. Quality beats quantity — one 45-min mock with structured feedback beats five silent LeetCode solves. Most candidates underprepare on the voice-explanation side specifically.
Practicing silently. Reading question lists and solving problems alone builds knowledge but not delivery. The real interview is a conversation — interviewer asks, you explain. Voice-paced practice with feedback is what actually transfers to live performance.
Pick the language you write fastest in for the real interview, and drill mocks in that language. Python is the most common at FAANG because it's terse. Java and C++ are also strong choices. PhantomCode grades language-appropriate idioms for all 11 supported languages.
Yes. PhantomCode's mock mode and live mode are the same model. Your mock-interview practice transfers literally — same patterns, same answer style, same edge-case discipline.
