Lead a deep dive on your most complex project

Past project deep dive (Staff/L6)

Pick the most complex system you’ve worked on and be prepared for a 30–45 minute deep dive.

Expect probing questions such as:

• Why did you choose this architecture?
• What constraints shaped the design (latency, cost, compliance, team skills)?
• Which decisions were wrong or suboptimal?
• If you could redesign it today, what would you change and why?
• What were the biggest risks, incidents, and operational lessons?

Explain the system clearly, defend trade-offs, and demonstrate reflection/learning.
