Pick your primary language now and align your practice to it
Imagine this comes up at work: "AI coding tools are allowed in the technical rounds. What's the correct way to use that and what's the trap?" Start with the practical move.
Step 1 of 2
Pick your primary language now and align your practice to it.
Pick a primary, keep two backups
- TypeScript
- Used at depth - generics, discriminated unions, strict mode. A strong default for the coding rounds.
- Rust
- Performance-critical paths. Pick it as primary only if you're genuinely fast in it under interview pressure.
- Python
- ML and eval tooling. Common backup; fine for the deep-dive discussion even if you code in TS.
Interview move
AI coding tools are allowed in the technicals, but you must understand every line you submit. Use Cursor the way you'd use it on the job - to move faster - then be ready to explain any line, justify a data-structure choice or rewrite a section by hand when asked. Pasting code you can't defend is the fastest way to fail a loop that explicitly tests for it.
