Reviews

Interviewing for a full stack developer role means demonstrating range: you’ll be expected to wire up backend logic, build performant interfaces, and explain how data moves from storage to screen. These problems are modeled on real coding assessments where candidates are asked to solve across both layers, often under time and complexity pressure. Expect tasks like building a dynamic feed from an API, writing database queries to support filtering and pagination, and handling UI rendering edge cases like loading states or stale data. You’ll also face scenarios where performance, security, and code readability must be balanced—and explained. These aren’t isolated frontend or backend problems but are connected workflows that mirror what full stack engineers actually build in production, and how they're evaluated in interviews.

"You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it."
