The full company-specific prep arc: the JD-based research report, followed by three mock interviews — each calibrated to the loop structure and bar identified in your report, covering the rounds you're most likely to face (e.g., coding, system design, behavioral). This is the narrowest, most targeted path to a specific company's loop — not a broad mentorship arc, but focused repetition against one real target. Built from 12+ years across PayPal, Goldman Sachs, and Amazon.
