今天牙痛很不想工作。我想說如果我明天就痛死了,這樣什麼都沒有留下很不好。
不如po一篇心得文。希望可以造福眾版友。
面試公司:Google/ Facebook / Adconion
面試職位:Machine Learning Software Engineer
求職方法: Google -> Google 求職網站投
Facebook -> 找HR
Adconion -> 找HR
背景:F1簽證學生 Columbia CS Masters就讀中。之前NTU CSIE畢業。
面試過程:
因為NDA,我不會說太多,都點到為止,如果想要問更詳細的,可以問我,
我會有限度的再說。
Google : (Received and accepted offer)
我投了3天以後,就接到通知說要phone interview,問題就是基本演算法。
還有問問我的研究這樣!
然後一週後HR打來,兩星期後去Mountain View onsite。
Onsite就四個人,一個人帶我去吃午餐。問題大概有:
一題System、好幾題演算法、
幾題open-ended problems、還有Map-Reduce。
一星期後,HR打電話給我,我正好在面FB。他就跟我說如果FB有上,
他會meet FB的compensation。
然後又一星期,HR寄信給我說,等等叫我開手機要打我手機。
我就開了,他就跟我講上了...
Facebook : (Rejected after onsite interview)
我打給FB HR的時候,Google已經快onsite了。
FB是一家迅速的公司,星期五通電話,下星期二就面試了。
面試就兩題演算法,我覺得比Google簡單,於是就onsite了。
Onsite的時候FB定錯旅館,讓我面試前一天只好住同學家,很不爽。
然後FB就三個interview。
第一個是Orientation跟系統設計。不過他都在問一些很刺的問題,
例如說:你研究所申請上哪幾間?
第二跟第三個就是出一些Data Structure或是演算法問題,然後寫code。
然後果然是被拒絕了。
Adconion : (Received and declined offer)
這家我沒有簽NDA,可以說多一點。申請這家是因為我想要留再紐約。
Phone Interview就寫個Lucky 7,
然後就NYC onsite。然後就四個人,問的問題如下:
演算法
1. 每給一個數字output現在看到所有數字之中的中位數
2. reverse a linked list
3. linkedlist 追趕問題
4. 在[4,5,6,7,8,9,1,2,3]這種array 作binary search
作業系統
1. 解釋synchronization
2. 解釋deadlock
3. 解釋LRU
網路
1. IPv6
2. 一些TCP/IP的東西
程式語言
1. Polymorphism
2. overloading vs overriding
3. DNS spoofing and detection
無法分類
1. 解釋Mean Value Theorem
Coding: (Java/C++)
1. thread-safe 環狀queue
2. LRU implementation
最後給我Offer的時候就說要我relocate,因為NYC沒有entry level,
可是那時候我還沒拿到Google,所以我就說
考慮relocate。結果我就拿到Google了,然後他說CTO想跟我談,
我就只好說sorry了,不過他說他們還有再招ML的人,
有興趣可以再聯絡他。
心得:
我覺得,找工作基礎真的是要練好。另外就是表達能力,要能把東西講清楚。
然後我覺得要多投幾家,不想要去的當練習,反正多面幾家不吃虧。
我記得我當時三家都在等的時候,心情超不好,FB又把我拒掉了,
壓力超大。後來我覺得其實公司很多啦!
也不是說一定要這幾家,所以多申請多健康,
累積經驗,拿到offer還可以跟別的公司談薪水。
最後,希望大家找工作順利。
