What is the CSS box model?1 / 10

Every element is a box composed of content, padding, border, and margin (inner to outer). `box-sizing: border-box` makes width/height include padding and border — the common modern default that avoids surprising sizing.

What is the compound component pattern?1 / 10

Multiple components share implicit state via Context rather than explicit prop drilling. E.g. `<Select>` + `<Select.Option>` communicate via a shared context, giving consumers a composable API without complex prop hierarchies.

How do interfaces work in Go?1 / 10

Go interfaces are satisfied implicitly — a type implements an interface simply by having the required methods, with no `implements` keyword. This enables structural typing and decoupling. The empty interface `interface{}` (or `any`) matches every type.

What is a graceful shutdown and how do you implement it in Node?1 / 10

Graceful shutdown stops accepting new connections, waits for in-flight requests to complete, and then exits cleanly. Implement by listening for SIGTERM/SIGINT, calling `server.close()` to stop accepting connections, and waiting for the close callback before calling `process.exit(0)`.

Define a deterministic finite automaton (DFA) as a 5-tuple.1 / 8

A DFA is M = (Q, Σ, δ, q₀, F) where Q is a finite set of states, Σ is a finite alphabet, δ: Q × Σ → Q is the (total) transition function, q₀ ∈ Q is the start state, and F ⊆ Q is the set of accepting states. M accepts w ∈ Σ* iff the extended transition function δ̂(q₀, w) ∈ F.
