Software Engineer Skills

• Coding Skills: Latter solution is better than previous solution.
• System Design: Design high-level solution + verified each requirement and enhanced questions and facts (metrics, current system).

How to Deal with Uncertain Problems

• Telemetry First: Identify service dependencies and understand how services interact.
• Explore Service Endpoints: Examine the HTTP and gRPC endpoints exposed by each service.
• High-Level Thinking (Intuitive Curiosity): Understand the overall architecture and product vision from Figma designs and system design documents.
• Explore the Flow: Trace the end-to-end request flow and identify the core functions within the codebase.
• Testing: Run the application and test API endpoints to verify inputs, outputs, and expected behavior.
• Coding: Optimize the implementation and perform thorough code reviews.
• Monitoring: Add meaningful metrics, logs, and alerts to observe the health and performance of the feature.

Grill weaknesses

• Meta thinking first: Draw high-level idea map before doing anything.
• Structured Thinking: Order the actions.
• Implementation Skills: Understand full flow, not only tickets.
• Retain long-term knowledge: store facts, feedback, concepts, active retrieve it in long-term knowledge base.
• Present for impact (teach, convince, motivate): stimulate to explain your thinking for other people follow Feynman Technique, 3-sentences rules for other needs, use body language and focus to main point to grab user attention.
• Improve quality of outreach, connections: enhance outreach to open communicate with strangers, value connections, and make service for community.

Frame A Decision

• Fact is what happening. Proposal comes with trade-offs and reasons.
• Needs are about survival. Wants are about desires.
• How to learn new thing: See it (mostly 70%). Do it (for high-execution required skills). Feedback it (be corrective feedback with insights)
