学术养生
父母住在学校2000年左右建的教师家属小区里。 当时能够住进去的多是与我父母年岁相当的人。他们互相之间即是大学校友，也是同校教师即同事，同时还是邻居：从刚刚毕业时的青年教师宿舍，到新婚后分配的八平米单间筒子楼式公寓。他们几乎一生都生活在校园里，买菜都不用出校门，与自己的同事或邻居们一起排队，继续聊着其他场合中未完的话题。唯一的变化是那每四年或五年一换的学生们。
这次回国见到父母的老朋友们，许多还是我出生时的筒子楼里的老邻居。他们如今大多87-95岁左右，身体健康。我还是毕恭毕敬的“阿姨，叔叔”的叫着。 有一位上海阿姨还上来掐我脸蛋子。我说： X阿姨，我6岁时你掐我脸蛋子，如今我都60多了，您老可不能再掐了。这不，脸上的褶子又多了两条。

感觉这个小区就像是一个居民们一起从青年变老年的社区。在小区里蹓达一圈，就能碰上许多90以上的老人，精神抖擞，声音洪亮的聊天散步。听保姆说疫情刚开放的几周之内，仅这小区里就有七十多位老人去世，不然他们活到100多岁没问题。
这些挺过了疫情的老人们不但长寿， 思路也还很清晰。一位女教授87岁时还上大课，全程站立，声音响亮不用扩音器，后排学生都能听到。八九十岁的老教授每年还去给100多岁的老师拜年。

我爸现在每周还去实验室几次，和一个比他还老的老头一起讨论什么东西。很难想象他们如今还会有什么正经的研究成果，但我弟说这叫做＂学术养生＂，别人吃补药养生，他们以此为补。一旦停下来，怕是各种毛病会全来了。
我妈两年前还开着那种电动自行车到处跑，与人撞过好几回。听我弟说，老太太从不讹人。摔倒了爬起来，拍拍衣服就跑了。可是咱也得为学校里这些孩子的安全着想啊，万一把下一位国家领导人给撞了呢？我弟就把电动车给没收了。
我父母除了中青年时期经常去干校，下工地，干苦力活，50岁后从不锻练，吃饭也不低碳。我妈还不喜欢按时吃降压降血糖药。保姆用的一个不粘锅至少20年了，如今就跟那开了锅的铁锅一样，达到了不粘锅的又一个新高度。那层PFOA膜，怕是早被他们吃肚儿里了。

人老了自己有自己的主意。我建议的保健长寿方法自然是没人听，用我妈的话说：你也活个90岁让我瞧瞧！

“以旧换新”政策拉动“金九银十”
全国乘用车市场信息联席会秘书长崔东树表示，除了新车密集上市潮，国家报废更新政策及各地方以旧换新置换政策稳定发力，共同拉动车市增长。
“叠加中秋和‘十一’的节日效应，9月车市呈高速增长态势，‘金九’效果显著。”他告诉证券时报·e公司记者，随着国家对汽车报废更新补贴力度的加强，市场回暖对车市起到明显的拉动效果，价格战对车企的压力相对减缓，年末车市将进入持续走强的良好态势。

事实上，从8月第二轮汽车以旧换新政策细则正式出台以来，各省、直辖市关于汽车置换更新补贴的政策逐步落地，截至9月29日已有31个地区出台了具体政策。
信达证券的研究报告显示，在原有国家层面关于报废更新补贴的基础上，各省、直辖市对于转让旧车并购买新能源乘用车或燃油乘用车，均出台了对应的置换补贴政策。大多数地区以价格带划分补贴等级，且并未限制新购车型价格上限。对于新购新能源乘用车的消费者，补贴金额普遍更高，如云南、海南、青海最高补贴金额可达2万元。除置换补贴之外，青海、西藏等地还对新车购置出台补贴政策，最高补贴金额可达1.8万元。
该报告认为，随着各地区置换政策逐步落地，叠加新车供给旺盛，潜在的换购需求有望进一步被挖掘，且大多数地区要求的新车购买时间是置换补贴发布之日开始到年末，有望进一步提升“金九银十”传统旺季车市景气度。

工作市场竞争加剧是未来的常态，这种状态下的选校的思维
角度1：最强的孩子去哪儿都一样。这个可能对但未必全对。选校的目的不是证明自己多强，而是学校能否带来额外收益。一个不善于发挥软性资源的孩子，长期能走多远？所以答案恰恰是，越是强的孩子，越要考虑如何有选择性的领域，最好不要趋同。
角度2：名校是否有光环。肯定是有的，特别是对于中间部分的，名校加持的作用更明显。
角度3：行业退潮对什么部分影响最大。CS 的繁荣期（是个毕业生都有工作，而且收入大大超过其他行业）不可能永远这样。看看法学院，商学院的几十年的情况就清楚了，一线的学院还会很好，但后面的就业前景可能就非常一般了。所以竞争优势会向头部的集中。

### **Behavioral Question:**
**"Tell me about a time when you had to handle conflicting priorities on a project. How did you manage it, and what was the result?"**

### **Good Example Answer:**
"While leading a project to develop a new feature for our product, I encountered conflicting priorities from two different teams. The sales team wanted the feature to be delivered quickly to meet a client’s urgent request, while the engineering team was concerned about ensuring the feature was fully tested and met quality standards before release. Both priorities were valid, but they created tension regarding the timeline.

To address this, I first held meetings with both teams separately to fully understand their concerns and requirements. I realized that the sales team’s urgency was tied to a specific client demo, while the engineering team needed extra time for testing to ensure we wouldn’t introduce bugs. I brought both teams together for a joint meeting, where we discussed the constraints and came to a compromise.

We decided to prioritize a minimal viable version (MVP) of the feature for the client demo that would meet their core needs without overloading the development timeline. At the same time, we allocated time after the demo to complete additional testing and implement the full version of the feature. By clearly defining the scope and communicating openly with both teams, we were able to balance the conflicting priorities effectively.

The demo went well, and the client was happy with the MVP. The full feature was delivered two weeks later with all the necessary testing, and it was released without any major issues. The experience taught me the importance of facilitating collaboration, setting clear expectations, and finding a balanced solution when managing competing demands."

---

### **What You Should Not Say:**

1. **"I ignored the concerns of one team and focused solely on the more vocal team’s priorities."**
  - Demonstrates an inability to manage competing interests and risks alienating key stakeholders.

2. **"I tried to meet both demands without compromising, which led to an overstressed team and subpar results."**
  - Shows poor prioritization and lack of negotiation skills, leading to potential burnout and quality issues.

3. **"I didn’t consult with the teams and made a unilateral decision on my own."**
  - Reflects poor collaboration and decision-making, which could lead to friction and lack of team buy-in.

4. **"I delayed the project indefinitely because I couldn’t decide how to handle the conflicting priorities."**
  - Indicates indecisiveness and an inability to take action in a timely manner.

5. **"I compromised quality to meet the deadline, which caused issues after the feature was released."**
  - Suggests a short-term focus without considering the long-term impact of sacrificing quality.

### **Behavioral Question:**
**"Tell me about a time when you encountered a major roadblock in a project. How did you handle it, and what was the outcome?"**

### **Good Example Answer:**
"During a project to build a new feature for our platform, we hit a significant roadblock when a critical third-party API we were relying on became unreliable, causing data inconsistencies. The feature’s functionality depended heavily on this API, and without stable data, we couldn’t move forward. The project was already halfway through development, and deadlines were approaching.

I immediately convened a meeting with the team to assess the situation and explore potential solutions. Rather than halting the entire project, we decided to isolate the feature components that didn’t rely on the external API, allowing the rest of the development to continue while we figured out a way to handle the unreliable data source.

Next, I worked with the engineering team to create a caching mechanism to mitigate the impact of the API’s downtime. This allowed us to serve users previously fetched data while the API was unavailable, ensuring minimal disruption to the user experience. We also added more robust error handling to gracefully manage any API failures, giving the application a fallback system.

I made sure to keep stakeholders informed throughout the process, explaining the issue, the steps we were taking to resolve it, and how this affected the timeline. Once the caching system was implemented and tested, we were able to continue development and meet the original deadline with only a slight adjustment to our feature scope. In the end, the project was delivered on time, and the fallback system we implemented even improved the platform’s resilience against future third-party API issues. This experience taught me the importance of adaptability, creative problem-solving, and transparent communication when dealing with unexpected challenges."

---

### **What You Should Not Say:**

1. **"I waited for the third-party API to stabilize instead of trying to find a workaround."**
  - Suggests passivity and a lack of initiative in finding alternative solutions.

2. **"I didn’t communicate with the team or stakeholders and just tried to fix it on my own."**
  - Indicates poor collaboration and failure to keep key stakeholders informed, which can lead to confusion and frustration.

3. **"I focused solely on fixing the API issue and let the rest of the project stall."**
  - Reflects an inability to manage parallel tasks or find ways to keep the project moving forward despite roadblocks.

4. **"I blamed the third-party service for the delay and didn’t take ownership of the solution."**
  - Shows a lack of accountability and problem ownership, which is critical when facing external challenges.

5. **"I made changes to the system without fully testing the fallback, which caused more issues later."**
  - Highlights poor attention to detail and testing, which can lead to greater problems down the line.

### **Behavioral Question:**
**"Tell me about a time when you had to refactor or redesign a front-end component due to performance issues. How did you approach the problem, and what was the outcome?"**

### **Good Example Answer:**
"While working on a web application, we started receiving complaints from users that a key dashboard component was loading slowly, especially when handling large datasets. This component was crucial for users to analyze data, and the performance issues were affecting the overall user experience.

I began by profiling the application to identify performance bottlenecks. The main issue turned out to be inefficient rendering due to the way we were handling data updates—every time the data changed, the entire component re-rendered, even for minor updates. Additionally, the component wasn’t optimized for virtual scrolling, which led to heavy memory usage when large datasets were loaded.

To resolve this, I first refactored the component to implement React's `shouldComponentUpdate` and memoization techniques, ensuring that only the necessary parts of the UI re-rendered when data changed. I also introduced virtualized lists to handle large data more efficiently, allowing the dashboard to render only the visible rows instead of the entire dataset at once.

Next, I optimized the data fetching logic by implementing lazy loading, so that the dashboard only retrieved data when the user needed it, reducing initial load times. Throughout the process, I kept close communication with the design and backend teams to ensure that the changes didn’t break any existing features or APIs.

After these optimizations, we saw a 40% improvement in load times and smoother interaction with large datasets. User feedback was overwhelmingly positive, and the application became much more responsive, particularly for our power users who dealt with large data daily. The experience reinforced the importance of profiling performance issues early and leveraging techniques like memoization and virtualization to improve front-end efficiency."

---

### **What You Should Not Say:**

1. **"I decided to rebuild the entire component from scratch without analyzing the root cause of the issue."**
  - Shows a lack of problem-solving focus, opting for a complete rebuild instead of targeting the specific performance bottlenecks.

2. **"I didn’t bother profiling the application and just tried random fixes until something worked."**
  - Reflects a trial-and-error approach rather than a structured, data-driven approach to problem-solving.

3. **"I focused only on fixing the performance issue but didn’t test for any potential breakages or regressions."**
  - Suggests a lack of thoroughness, which could lead to new bugs or issues in other parts of the application.

4. **"I didn’t communicate with the backend or design teams, so I implemented changes that caused inconsistencies with other components."**
  - Demonstrates poor collaboration, which can result in misalignment and unexpected issues when integrating with other parts of the system.

5. **"I didn’t measure the performance improvements after making the changes, so I don’t know how effective they were."**
  - Indicates a lack of validation, which is crucial when solving performance issues to ensure the solution is impactful.
