自我介绍 · Self Introduction
"Tell me about yourself."
"Hi, I'm [Name], a recent graduate from [University] with a background in [Major]. During my internship at [Company], I worked on building data pipelines and dashboards to track key supply-side metrics for a ride-hailing platform — specifically, I identified a drop in driver acceptance rates during peak hours and helped the operations team adjust incentive structures to fix it.
I'm skilled in SQL, data visualization, and A/B testing. I'm excited about this role at DiDi's international business because I'm genuinely interested in how data can drive decisions across different markets — each country has a different competitive landscape, regulatory environment, and user behavior, which makes the analytical work much more complex and interesting."

业务理解 · Business Understanding
"What do you know about DiDi's international business?"
"DiDi's international business currently operates in 14 countries, with Latin America as its core market — particularly Brazil under the '99' brand and Mexico under DiDi, where they hold strong market leadership positions. The international segment has been growing at over 28% year-over-year in GTV, and recently turned profitable on an adjusted EBITDA basis.
What I find strategically interesting is DiDi's approach of building a 'super app' ecosystem in these markets — combining ride-hailing, food delivery, and financial services — which mirrors the playbook of Meituan in China. This creates multiple touchpoints to improve user LTV and reduce churn."
这段话展示了你真的做了功课，面试官会印象深刻。
数据分析 · Data Analysis
"Walk me through how you'd analyze a metric drop."
"My approach follows a structured framework. First, I'd verify the data itself — check for pipeline issues, timezone mismatches, or definition changes. Then I'd decompose the metric across dimensions: by city, time of day, user segment, and trip type to isolate where the drop is concentrated.
Next, I'd separate supply-side from demand-side factors. For a completion rate drop, for example, I'd look at whether acceptance rate or trip cancellation rate changed. Then I'd investigate internal causes — any product changes or policy updates — versus external causes like weather, holidays, or competitor promotions. Finally, I'd form a hypothesis, validate it with data, and recommend a concrete action."
说完这段，面试官通常会追问「那如果是某个具体指标下降呢」，你按框架继续拆就行。
