当时刚出校门找工作的我，天真地认为只要背诵好项目经历就可以了。虽然在背诵过程中很多次我能明显感受到面试官的不耐烦，我都没有想到要改变策略，直到有一次我忘词了，当时只有几秒种的反应时间，所以只能硬着头皮思考，用自己的逻辑来回答，却意想不到的第一次获得了面试官的赞许！
With this positive experience under my belt, I started to talk impromptu a lot more during the interviews, rather than relying on mechanic recitation. 结果，用这样的沟通方式和 hiring manager 交流效果比以前好太多！一来二回，impromptu and organic conversation also helped me become a better thinker, 极大地锻炼了我的思考能力，以及快速地从非常 abstract 的信息中提炼出思维框架和逻辑链。很快，我就拿到了 offer! 这次我自以为的失误，却让我真正明白在面试中如何和 hiring manager 交流！What I learned --
Effective communication 不是简单的背诵项目经历。它是一项全方位技能要求很高的技能
Data analyst and data scientist are business roles, 我们的分析是要通过和 stakeholder 合作才能落地的，所以如何把分析思路讲成一个 convincing story, 自圆其说还要让人信服，这种沟通能力其实比分析要难，比分析重要，而这也是我们中国同学在面试中的减分项和难点。I hear this often:
"还有对job search最致命的，就是不知道如何用professional语言和方法去表达自己，展示自己。"
"口语并不专业，我进入二面的几率几乎为零"
First, what qualifies as effective communication?
要让hiring manager 对你印象深刻，your communication needs to have these components, 缺一不可
- Poise. Can you function under pressure?
- Personality. Are you curious?
- Quick thinking. Can you develop a framework to tackle a problem with imperfect information?
- Reasoning skills. Are you capable of logical thinking?
比如面试中要考的 product sense，你的这个 sense 必须是通过语言这个载体来呈现的，这个交流过程既抽象又具体。
抽象在你的思维，具体在：你要通过有穿透力的语言来准确无误地展现这个抽象的东西，真的不是能用英语简单沟通就可以的。这其实是大多数中国同学拿不到 offer 的一个大碍，也是他们的一大误区，认为面试前只要来几场 mock interview 就可以了
Communication is thinking. A messy communication is indicative of a messy mind. And your quick thinking and reasoning skills will have to be based on your in-depth understanding of business and its underlying mechanism.
公司愿意高价买单的永远是你的头脑, 有条不紊，思维逻辑清晰地回答问题是DA/DS 的面试重点，你的用词，结构，以及句子和句子之间的逻辑排序向公司展现了你的思维能力。这些支撑 effective communication 后面的知识是需要你自己积累和沉淀的，这篇文章不可能赘述。
But I can definitely give you some tactical tips on how to ensure the clarity of your communication, and give you some sentence structures you can use during your next interview.
Tip #1 - Learn to summarize. Always start with a high level statement to summarize what you are about to say, before you say anything, otherwise you will lose the hiring manager at hello :)
这也是中国同学的一大误区，一上来就讲细节，让人听了不知所云，因为没有 context! Context will prepare the listener and give meaning to what you want to say. In business, we call it POV, or point of view.
Tip #2 - Learn to use the right sentence structure, and use connecting words to join ideas together
如果把单词想象成珍珠，而 sentence structure 和 connecting words 就是把它们串成一条项链的线，那么它们在oral communication 中的重要性可想而知。
Here are some sentence structures you can use to establish clarity in your communication.
