Google L6 Loop
System design and leadership carry the L6 decision, and strong coding is assumed. Candidates who code well but show senior-level design and strategy are often offered L5.

What the L6 Loop Weighs
- The design bar is well above L5: cover multi-datacenter availability, partitioning, and how the system evolves.
- Leadership stories should span several teams and show how you built agreement.
- Credit the team in your stories, and avoid criticizing past work or colleagues.
- Coding is fewer rounds, and it still needs to be correct and clearly communicated.
