HTTP & the Web: The Absolute Basics
Requests, responses, methods, and status codes — the vocabulary everything else builds on.
What this session covers
- Every web interaction is a request-response pair: a client asks, a server answers — even a webpage load is just this repeated hundreds of times.
- The 5 methods worth knowing cold: GET (read), POST (create), PUT/PATCH (update), DELETE (remove).
- Status codes cluster by first digit: 2xx = success, 3xx = redirect, 4xx = you (the client) made a mistake, 5xx = the server made a mistake.
- Headers carry metadata (auth tokens, content type) separately from the body — mixing these up is a common early mistake when debugging.
What fresh graduate FDE interviews look for
At the fresh-graduate level, FDE interviewers mostly test technical literacy and coachability: can you read API documentation, reason about HTTP and JSON, debug from an error message, and stay clear and honest with a customer when you don't know the answer yet.
