The Software Engineer's Interview Stack: What to Actually Practice in 2026
LeetCode alone won't cut it anymore. Here's the modern interview prep stack for engineers who want offers.
Five years ago, the engineering interview was a LeetCode grind. Today you'll face system design, behavioral, take-homes, and AI-collaboration rounds.
The 5-layer interview stack
- Coding (35%): patterns over volume
- System design (25%): 4 building blocks + 6 archetypes
- Behavioral (20%): 6–8 STAR-R stories
- AI collaboration (10%): explain when to trust AI output
- Communication & pacing (10%): tight 2-minute walkthroughs
