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.

Principles

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)

Viết về framework để làm việc hiệu quả hơn

Sau đây là note cho framework để làm việc hiệu quả hơn.

1. Meeting

Using Ne: Idea -> Idea.
Cần hướng ngoại, verify từng cái Idea 1 and Idea 2

2. Implementing

Using Ti + Si: break the task and detail each steps.
Cần năng lượng introverted, focus, details có thể làm ban ngày hoặc đêm

3. Translating ideas

Using Fe: Cần dùng term của người mình communicate with: PM, designer.
Aware intense communication: assertiveness and energy của người khác.

4. Learning about UI/UX + Writing Docs

Đọc docs EH: https://help.employmenthero.com/hc/en-au/articles/15717612239375-HeroForce-leave-request-submission-and-management-FAQs
Ngắn gọn, trọng tâm, không tạo cảm giác người khác khó chịu.

5. Signal and Emotionally Trigger (Motivation)

Leader không hiểu được team đâu, họ chỉ nhìn cái signal thôi.
Để motivate team, dùng lý không được đâu, cách hiệu quả hơn là dùng emotionally trigger.

6. Think by trade-offs

Nghĩ gì 1 cái solution thì nghĩ theo trade-offs, thay vì đúng sai.
