System Design Mock Interview

Most engineers think they are good at system design until they sit in a real senior round. I will run this exactly the way top product companies conduct it, open-ended problem, time pressure, no hand-holding. Then a full debrief on where you lost depth, whether your trade-offs were well-reasoned, and how your communication held up. Engineers who do this mock before their real interview consistently report it as the most useful session in their entire prep.
