How to Prepare a Promotion PPT and Interview: Structure, Technical Difficulty Description, and Project Value Highlight

The Technical Center offers two promotion opportunities each year, and many candidates are unsure how to prepare.

I have served as a promotion examiner for five sessions and have summarized the preparation process.

This article is divided into two major parts:

1. How to write a promotion PPT.

2. How to conduct a promotion interview.

Below I will explain each part in detail.

1. How to Write a Promotion PPT

The PPT itself can be divided into three sections:

(1) Designing the PPT structure.

(2) Describing technical difficulties from a technical perspective.

(3) Highlighting the project’s value.

1) PPT Structure Design

A classic example of structured expression is the “Pyramid Principle”. Using this principle, the presentation follows a top‑down hierarchy.

The core idea can be summed up as: Conclusion first, then supporting points, grouped logically, progressing step by step.

Prioritize importance, start with the global view before details, present conclusions before reasons, and results before processes.

When describing a project, first state the project name and outcome, then present several supporting arguments. These arguments should be concrete and backed by evidence.

Group the arguments using the MECE rule – they must be mutually exclusive and collectively exhaustive.

Each argument should be supported by no more than seven pieces of evidence.

To make the narrative engaging, you can use the SCQ method (Situation, Conflict, Question). For example, the “todo2.0” project:

Background: The original todo system was cumbersome and rarely used, despite a flashy UI and modern technologies like Node.js and Go.

Conflict: Different departments used disparate solutions, leading to inconsistent communication and low efficiency.

Question: Could we consolidate task assignment and project management into a single system to improve collaboration?

After three months of closed‑door development, todo2.0 was launched, solving the identified problems.

Using a mind map can further clarify the PPT structure by listing topics, categorizing them, and aligning arguments.

2) How to Describe Technical Difficulties

This section is also split into three points:

1) What constitutes a difficulty?

2) What technical difficulties can be discussed?

3) How to describe and express those difficulties?

1) What constitutes a difficulty? A difficulty is something you have not done before or cannot handle yet – essentially your personal technical blind spot.

2) Types of technical difficulties you can talk about:

1. Learning a new domain (e.g., a front‑end engineer doing back‑end work).

2. Tackling something you previously avoided (e.g., implementing a protocol‑forwarding system).

3. Turning past failures into successes (e.g., improving project‑management processes).

4. Achieving something no one else has done (e.g., building an H5 platform).

5. Doing an existing task better than before (e.g., creating a superior version of todo).

3) How to describe difficulties:

Use the SCQ method or the following two techniques:

First, tell a story – use chronological or spatial cues (e.g., “once, now, future” or “from A to B”).

Second, let data speak – use charts or comparative tables to illustrate the challenge.

3) How to Highlight Project Value

Value can be measured by time and money. Explain how your work saves labor hours, improves efficiency, reduces costs, or generates revenue.

Examples:

1) Time : How many person‑hours were saved?

2) Time : How many people became more efficient?

3) Money : How much cost was reduced?

4) Money : How much revenue was generated?

2. How to Conduct the Promotion Interview

After the PPT is ready, you face the oral defense. Overcome nervousness by thorough preparation.

1) Preparation:

• Review the competency model for the target level – questions will stay within that scope.

• Re‑study the knowledge points listed in the model, especially those covered in the Technical Center’s training sessions.

• Draft a speech script and rehearse until you can present without notes; keep key points in PPT notes as a backup.

2) On‑stage performance:

Be authentic – never claim others’ work as your own. Examiners can detect inconsistencies.

Adopt a growth mindset: promotion is not guaranteed, but the process helps you identify gaps and improve.

Treat the interview as a self‑development opportunity; the feedback you receive is valuable.

Finally, stand up and speak confidently. Standing projects confidence, makes your voice louder and your presence stronger.

In summary, follow these steps to increase your chances of a successful promotion.
