An interview prep path for full-stack loops. Full-stack interviews test breadth on both sides of the API plus the same coding bar as everyone else. This path balances the legs: TypeScript and framework fundamentals, database and distributed-systems vocabulary, a coding ramp from easy through a couple of hards, the four system designs full-stack loops reach for, and the behavioral themes that prove end-to-end ownership.
The client half of the breadth check. Interviewers want the language and the rendering model, not framework trivia - know what TypeScript buys you and what your framework costs you.
The server half: indexing, transactions, SQL vs NoSQL trade-offs, and the distributed-systems vocabulary that system design rounds assume. Full-stack candidates most often get dinged here - do not skim this section.
Warm-ups that lock in hash maps, two pointers, and linked-list handling. Full-stack loops hold you to the same coding bar as specialist roles - make these reflexive before climbing.
Where most full-stack loops get decided. Aim for ~25 minutes per problem with a clean solution and a concrete time/space analysis - then say it out loud, because the narration is graded too.
A short hard ramp - enough to handle the one stretch problem some loops include. LRU cache in particular doubles as a systems conversation: eviction, capacity, and what you would change for a distributed version.
The four bounded designs that dominate mid-level loops. As a full-stack candidate, your edge is covering both ends - talk about the client experience and the storage layer in the same answer.
Full-stack behavioral rounds screen for whether you actually own features front to back or just touch both codebases. Build STAR answers that follow one feature from design through deploy and incident.
Enough SQL to own the data layer end to end: joins, aggregation, and the subquery patterns that come up when an interviewer asks you to answer a product question directly from the database.
API design in both flavours, plus the complexity and tradeoff sheets worth re-reading before a design round.
