Kodingsintervjuer evaluerer problemløsning og kommunikasjon, ikke bare å få rett svar. Å lykkes innebærer en klar tilnærming (forstå, planlegg, kod, test), kommunikasjon gjennom hele prosessen, og å håndtere problemet metodisk.
En strukturert tilnærming
1. UNDERSTAND the problem → clarify requirements, ask questions, confirm inputs/outputs,
edge cases (don't jump straight to coding)
2. PLAN → think through an approach; discuss it BEFORE coding; consider complexity/trade-offs
3. CODE → implement cleanly; explain as you go; write readable code
4. TEST → walk through with examples (incl. edge cases); find and fix bugs
→ a methodical approach shows engineering thinking (what they're really assessing).
