### 職缺所需能力：

#### Minimum qualifications:
- CS學士學位或相等實務經驗
- 成大資工學士&碩士
- 具備一種或多種程式語言(例如：Python, C++, Java)的3年軟體開發經驗
- 刷題跟開發多以C++為主，Python還不熟悉
- 具備以下一項或多項經驗：Unix/Linux environments, [distributed and parallel systems](https://www.geeksforgeeks.org/operating-system-difference-between-distributed-system-and-parallel-system/), service development, machine learning
- distributed and parallel systems還沒有到很了解；service development沒有相關經驗
- 具備物件導向程式語言能力
- 除了C++之外，JavaScript也有兩三年的開發經驗
#### Preferred qualifications:
- 具備以下經驗：algorithms, [data infrastructure](https://en.wikipedia.org/wiki/Data_infrastructure), data analysis, system evaluation and testing
- 演算法及資料分析有修課經驗；data infrastructure跟系統評估與測試沒有相關經驗
### 匹配度分析：
1. 這個職位跟我目前碰過的領域沒有很重疊，硬要說的話大概只有程式能力的要求有對上，以及對於演算法和資料分析有概念。
2. 目前在做的研究是演算法設計，會直接從數學上去證明演算法的理論上/下限在哪，會更精準的判斷這個演算法的優缺點及應用場景（但我不確定這種理論的東西在實際的產品開發到底有沒有用處）。
3. 這個職缺會希望有測試跟評估的能力，我缺乏對實際產品或大型專案做分析的經驗，如果要補這個能力的話，目前想到的方法是去實習or參與大型專案。
4. 總結來說，這份職缺是比較偏向自身興趣的（對於Google Nest這種跟使用者互動的智慧家居型產品有興趣），但如果要找這類的職缺，感覺這個領域的專業知識跟algorithm是個需要補好的洞。

## 面試題目

## 模擬面試
>interviewer: 🤖
>interviewee: 👀

🤖：請你先簡單的自我介紹一下
👀：我是XXX，畢業於成功大學資訊系，目前就讀成功大學資訊所碩二，預計明年8月會畢業。我在大二的時候在學校的計網中心打工，負責的內容是互動式網頁的功能維護及新增，使用到的程式語言有HTML, CSS和JavaScript。該互動式網頁主要功能為將JavaScript檔案中不同的模組、類別和函式建立圖形化的關聯。大三的專題是寫一套JavaScript文檔轉換閱讀系統，第一個介面會先將一份或多份的JavaScript檔案依照schema的定義轉換成MongoDB的物件形式並存入後端資料庫，然後另一個介面會把資料庫中指定文檔抓出來，並顯示成方便瀏覽的文件網站，以此大幅降低大型專案trace code的時間成本。使用到的技術有Node.js和MongoDB。大四在學習SQL的時候建立個一個簡易的遊戲查找系統，可以透過網頁內嵌按鈕或使用者自行輸入的方式使用MySQL去後端抓對應的資料出來顯示（例如遊戲上市日期、角色...等資訊）。碩一修了蠻多AI和機器學習的課，對於常見的任務類型跟常用的模型都有所了解。
🤖：聽起來你做過蠻多網頁前後端的開發，在這個過程有遇到什麼瓶頸嗎？遇到又是如何解決的？
👀：有，當初在做JavaScript文檔轉換閱讀系統時，因為還不熟悉系統設計流程，直接讓全部負責parsing的function都在網頁前端跑，這樣會讓網頁在轉換的時候卡住，而萬一轉換流程出現預期以外的錯誤也會導致網頁crash掉。當時是負責帶我的學長發現的，他建議我可以把負責轉換的function交給worker來執行，這樣它會在獨立的背景執行緒執行，不會跟網頁的JavaScript搶CPU。
🤖：好，那你的parser是怎麼運作的，可以簡單講一下他的原理嗎？
👀：沒問題，一開始我是透過JavaScript文檔的特性去抓關鍵字，例如應該被判斷成類別的class跟其他地方出現的class有什麼不同，因此當時的開發相當於遇到什麼就去改條件，等於說parser對於JavaScript文檔的限制多且容易出錯。後來學過編譯系統後，就運用所學去寫scanner去抓token，並透過gramma讓parser去轉換，以此讓轉換過程更穩定且不會出錯。
🤖：原來如此，那這邊想問你一些AI相關概念，可以請你解釋一下Semantic Segmentation和Instance Segmentation的差別嗎？
👀：Semantic Segmentation的重點在區分類別，所以假設圖片裡有三個人重疊在一起，他們會一起被分割成一個區塊，類別是人類。Instance Segmentation的重點是區分不同的物體，所以如果是上述的情況會將三個人分別切成不同區塊。
🤖：很好，那接著會需要考白板題...
👀：(REACTO...)
