System design interview assistant
A system design interview assistant helps you talk through architecture while the interviewer asks questions. OfferCC organizes requirements, estimates scale, suggests components, explains data flow, names bottlenecks, and states the trade-offs behind a design. It follows the live conversation, so a new constraint can update the next answer. Guidance stays in the local click-through overlay while you draw. Confirm the platform rules and the share preview before the round.
