The no-AI technical screen
Explain your answer to "Why does Cursor forbid AI beyond autocomplete on the first technical screens and how should that change your prep?" Add one concrete detail from the lesson.
Step 1 of 2
This is the screen people underprepare for. About 60 minutes, one medium-hard problem and no AI beyond editor autocomplete. Cursor's stated view is that programming without AI is still a strong time-boxed test of skill and intelligence.
If you've spent the last year letting an agent draft your loops and your data structures, this screen will expose it. The fix is mechanical: practice fundamentals cold until graphs, trees and concurrency come out of your hands without a model in the loop. Languages are commonly TypeScript, Go, Rust or Python - pick the one you're fastest in, not the one that looks impressive.
Core data structures: maps, heaps, queues, graphs.
Graph and tree traversal, often with a twist.
Concurrency: shared state, races, simple synchronization.
Clean production code under a 60-minute clock.
Solve mediums with AI fully off, on a timer.
Write real functions, not pseudocode.
Narrate tradeoffs out loud as you go.
Test edge cases yourself, since no model will.
Expect classic algorithm problems, sometimes with an infra or systems flavor. A rate limiter, a dependency graph, a scheduler or a log-merge are all fair game and play to your domain.

With no model to bail you out, the difference is process - not raw memory.
