I've also led a 5-person team delivering 3 core product modules.

What Are Your Strengths?

STAR Method Application:

S (Situation) - Background context T (Task) - Task objectives A (Action) - Action measures R (Result) - Results achieved

Example:

"My core strength is data analysis and problem-solving ability.

Specific Case: At my previous company [S], our mobile conversion rate continuously declined from 5% to 3%, affecting business growth [T]. My task was to find the cause and improve conversion rate.

[A] My approach was:

First established data tracking system, analyzed user behavior funnel

Through data discovered the problem was in the registration process, with severe user drop-off at step three

Collaborated with design and development teams to simplify registration process from 5 steps to 3

Conducted A/B testing for validation

What Are Your Weaknesses?

Strategy: Real but not fatal + Improvement actions

❌ Avoid Saying:

"I have no weaknesses"
"I'm too perfectionist" (cliché)
Core competency deficiencies

✅ Recommended Strategy:

Choose non-fatal weakness
Explain your awareness
Show improvement actions
Demonstrate growth mindset

Example:

"One of my growth areas is public speaking ability.

As a technical person, I previously focused more on coding and technical research. When doing technical sharing at large conferences, I would get somewhat nervous and my expression wasn't fluent enough.

After recognizing this, I took several actions:

Joined the company's Tech Talk group, doing monthly technical sharing

Joined Toastmasters speaking club

Proactively took on new employee training instructor work in the department

After six months of practice, I can now confidently share at 50-person conferences. While not perfect yet, the progress is obvious. This experience also made me realize that any skill can be improved through deliberate practice."

Salary Expectations

Strategy: Let them make the first offer

Standard Answer:

"Regarding salary, I believe your company has a mature compensation system. I'm more focused on the development opportunities and team atmosphere of this position. Could you first share the salary budget for this role?"

If You Must Give a Number:

"Based on my experience level and market research, my expected salary range is XX-XX thousand. However, I'll also consider other factors comprehensively, such as career development space, learning opportunities, team culture, etc. If the position is truly suitable, I have some flexibility on salary."
