首先非常感谢每位愿意提供意见、一起交流的乡民们，真的对我帮助很大 接续着前篇（台湾软体工程师越南求职之路） 经过一周的忐忑不安，DSV 终於通知我录取了！ 待遇是 1700 镁/月，共 13 个月，比起上一份台湾工作年薪多了约七万 虽然加薪幅度不大，但圆了一个越南工作梦，无价！ https://i.imgur.com/h1M1Gaw.jpg 原本心里其实一直在想面试时答得那麽卡，应该不会被录取的啊！ 导致这周沉浸在：「加强英文能力、加强专业能力」的心情下XD 完全没有好好调查胡志明市的生活水准以及注意事项... 而且对方询问能否在 8/1 就上工，超级紧凑！还好可以延後半个月 对於我这个完全没去过胡志明市的人来说，马上面临诸多考验 一、胡志明市第一郡租屋行情、须知 公司的位置在 Nguyen Thai Binh, Phuong Nguyen Thai Binh, Quan 1 就地图上来看算是非常市区 https://i.imgur.com/YRZBXqb.jpg 心想胡志明市在越南应该算跟台北同等，甚至更高消费水准的城市 会不会薪水不够付租金... 首先搜寻到了「背包客栈」的这篇去年的文章「胡志明市第一郡的长期租屋经验分享」 https://www.backpackers.com.tw/forum/showthread.php?t=1963119 里面提到的地点离公司真的非常近！月租费大约 250 镁，还算可以接受 https://i.imgur.com/AChzwU9.jpg 不过不清楚目前还租不租得到，要再花好几天做做功课了！ 二、工作经验证明已经能透过学校提供的打工证明 + 公司劳保记录搞定了 不过这个打工证明究竟能不能被认可，也是一大问题... 如果真的没办法，只能先联络看看代办以及公司能否有其他管道申请 面试时公司有提到签证的问题，他们说仅能提供邀请函，没办法帮忙处理签证申请 关於这点我觉得很正常，因为对方毕竟是越南的本土公司 完全没必要为了录取我这个外国人，还帮忙找代办来申请签证 所以原先就有必须自己搞定的觉悟了！ 三、生命会自己找到出路！ 原本认识越南只是一个小契机，没想到至今会对我带来这麽大的影响 包含学习越南语、认识越南朋友、亲自到越南走一遭、投递履历接着面试等 虽然不确定未来还会面对什麽挑战，但这段经验真的非常值得！且战且走吧！ 另外附上迟来的面试问题逐字稿，以及回答总整理XD (Q1) Could you tell me the main difference for those Java application which use JSP or Spring with Apache server versus those JavaScript application which use NodeJS server? What's the difference? How the mechanism is different? (A1) NodeJS is a V8-based runtime environment which uses an non-blocking I/O model. This means that it is a single-threaded runtime, it has a single call stack. But JSP or Spring with Apache server are both multi-threaded, blocking I/O based. --- (Q2) How do they handle the incoming request? In which case, NodeJS would be faster and which case NodeJS would be slower? compare to Java? (A2) For NodeJS, non-blocking I/O. If the incoming request is I/O bound such as file processing. NodeJS is likely to be faster than JSP. However if requests are CPU bound such as complicated algorithm: compression, sorting, searching something like that. The Java, Java Virtual Machine maybe faster than JavaScript, NodeJS. --- (Q3) You have been working with ReactJS also, right? Could you name some framework or library you've used? (A3) I've used Redux, RxJS and Styled-Components. --- (Q4) Could you tell me more about Redux? Why Redux exists? And what's the benefit of Redux in React? Do you know something about Flux? (A4) Redux brings "Predictable". As an react application gets more complex, some components may need to access the same state but display it in different ways. This situation makes the state harder to manage. Redux solves this state transfer problem and makes code clear. We can develop Presentational-Component and Container-Component separately, extracting the functional code from the component. Flux can be regarded as the father of Redux. One direction data flow is the core value of it. --- (Q5) You have used SQL-Server and Elasticsearch right? Could you describe the case you've used in Elasticsearch? (A5) Our product needs a fast, precise Full-Text searching system. However, the Full-Text searching function provided by SQL-Server is inadequate, especially in CJK terms searching: Chinese, Japanese and Korean. Elasticsearch ships with a wide range of built-in analyzers. These analyzers could determine how a string field in a document is transformed into terms. Choosing the right analyzer is as much art as science but I can only understand a few parts of it. --- (Q6) You setup Elasticsearch by yourself? Or someone setup for you? (A6) I setup ES for testing by myself through the official Docker image. It's very easy to setup the basic environment but difficult to leverage full power of its features. So, for production environment, the Infra-Engineer in my previous team would set and fine-tune the ES for us. --- (Q7) Could you describe how ReactJS work? Why ReactNative and ReactJS are faster than other libraries? What's the mechanism behind that? (A7) For example, we may modify the data directly on the DOM element in JQuery. The update logic becomes messy when large amount of complicated data are modified. And there is even no consistent rendering mechanism behind JQuery. Unnecessary rendering is happening again and again. ReactJS provides its own lifecycle, having a good grasp of the timing of re-rendering. With the Component design, we can also split the elements into smaller units. Only a small portion of the elements are re-rendered when data are updated, thereby increasing performance. --- (Q8) You know ReactJS application is Single-Page-Application right? It means you need to compile all of your JavaScript into one BIG file. And even if you ZIPPED it, your customer will still feel slow loading at the first time. How can I avoid it? How can I avoid this kind of situation? (A8) Webpack provides many kinds of feature for code splitting. For example, splitting chunks feature and lazy loading feature. We can even use Server-Side-Rendering to improve First User Interaction Time in our React Apps. --- (Q9) How do you scale a NodeJS server? How do you optimize or improve a NodeJS server's performance? (A9) We can run a NodeJS process on every CPU core and load balance all the requests among them through NodeJS's cluster mode. And Load-Balancing HTTP Server is another solution. Instead of using one beefy web server, I would divide up the task to many smaller web servers. --- --
