Bar Raiser. Leadership Principles. Structured loops. Senior+ system design. PhantomCode handles the formats that take FAANG offers from probable to actual.
Fast Think for the rapid-fire Meta coding round (90 minutes, 4 problems). Deep Think for the 60-minute L6 system design at Google where every trade-off needs justification. Switch modes mid-loop in one click.
Amazon's Bar Raiser is the single round most candidates underestimate. PhantomCode helps you map each behavioral story to the right Leadership Principle in real time, and coaches structure (situation → action → impact) without you re-typing the framework.
Senior+ system design isn't about knowing patterns — it's about knowing the trade-offs you've consciously rejected. PhantomCode surfaces the alternatives so you can argue against them, not just accept the first answer.
Python and C++ for Google. Java and Go for Meta. Swift for Apple. Stripe's Ruby/TypeScript stack. PhantomCode matches idioms — not just syntax — so the code reads like you've worked there.
FAANG loops are recorded for hiring-committee review — sometimes by Karat, sometimes by an internal recorder. The PhantomCode window stays out of every recording, no exceptions.
FAANG loops are 5-7 hours, 6+ rounds. By round 4 your memory of round 1 is unreliable. PhantomCode generates a transcript per round so you can debrief each one separately and prepare for the next-day's continuation.
Leadership Principles deep-dive in every round, not just behavioral. Bar Raiser interviews independently and can override.
Hiring committee debates packets you never see. L5+ rounds heavy on system design with explicit cost reasoning.
Two coding rounds, system design, behavioral, jam-packed pace. Code-reading and refactoring is its own format.
Deep technical specialization per team. Less standardized than peers — interviewer style varies wildly.
High-judgment, context-heavy. Senior bar by default. Behavioral signal weighted heavily.
Take-home walk-through is its own evaluation. Bug-bash and integration rounds are unique among the cohort.
Heavy on principled-engineering judgment. Code reviews of your take-home, model-eval-style discussions.
PhantomCode helps you stay sharp during a FAANG loop. It does not skip the fundamentals: you still need to know your CAP-theorem trade-offs, your behavioral story arcs, your time-complexity analysis. The candidates who get FAANG offers know the work — PhantomCode keeps them composed while showing it.
If your loop is two weeks away, drill the LPs and one system-design book first. Use PhantomCode in the actual rounds and read the transcripts between days for sharper next-round prep.
