A round-by-round breakdown of what frontend interviews actually test — DOM fundamentals, component architecture, accessibility, performance — plus a two-week plan.
A round-by-round look at what backend interviews actually test — data structures, database modeling, distributed-systems design — plus a two-week study plan.
Full-stack loops grade breadth across both halves of the stack at once — here's what each half actually tests, plus a two-week plan for shoring up your weaker side.
Mobile interviews grade platform judgment as much as coding — offline design, device constraints, App Store review — and this guide maps each round plus a two-week plan.
Swift syntax is table stakes in an iOS interview — the rounds actually hinge on memory management, architecture judgment, and App Store review, mapped here with a two-week plan.
Most Android candidates over-index on LeetCode and walk into the Compose-and-lifecycle round with nothing rehearsed — this guide maps every stage of the loop and what each one actually grades.
