别让斑竹影响我们的心情,Google的招聘试题

Google,全世界都知道的名词,虚拟世界里最真实的童话。Google位于美国加州的总部,豪华得像神话中才会出现的仙女岩洞———门户玄关上,挂着几百盏迷幻熔岩灯;健身球与M&M’S巧克力唾手可及;知名迷幻乐团GratefulDead的大厨,24小时待命为员工们准备免费餐点;电动滑板车和儿童玩具车穿梭于办公室之间,车上坐着抱满了文件的员工。
办公室里一排排坐着奇装异服的百万富翁,他们手握大把员工股票,市值145美元一股。

梦想在这儿办公?先称称自己的分量!

10月底,Google开始了新一轮的员工招聘……

“书蠹头”拒之门外


想成为Google的编程工程师,最好有点想象力。否则,别说进入Google,恐怕连招聘广告你都看不懂!

10月底,Google在美国《麻省技术评论》、《LinuxJournal》、《Mensa》、《今日物理》等几本专业杂志上,刊登了一份“Google实验室能力倾向测试”。

试卷开头,蛊惑地写着“试试看!把答案寄回Google,你有希望去Google总部参观,并成为我们其中一员”。

测试只有21个问题。道道刁钻,剑走偏锋。

实打实的数学题,比如“用3种颜色为20面体上色,每个面一种颜色,有多少种组合?你会选择哪3种颜色”。

毫无头绪的主观题:“什么是世上最美的数学方程式?”

和数不清的自由发挥题:“以下空白,填上点好东西”或者“用你的画笔,改变这张考卷的外观”……

全球顶尖高校的BBS上,都流传着这份测试题,和各式各样确定或不确定的答案。

“几天之内,Google总部收到了成千上万份答案。”Google的副总裁艾伦·尤斯塔斯说,“其中有很多来自经济学家、教授和高智商人士。他们无意应聘,只想挑战一下自己的能力。”

重金悬赏“金头脑”


Google拨出5万美元基金,等待投出答案的天才程序员。

只要冲到最后一轮淘汰赛,Google就用这笔钱,招待他们去Google加州的“梦幻总部”面试。不入选,也能免费玩一遭,何乐不为。

说到“手面奢侈”,Google当仁不让。

除了善待自个儿的员工,高额分红配股,把他们像托儿所小孩一样照顾,Google每年还在网络上“现金悬赏”,招聘“猎人”编写高难度程序。

去年,“揭皇榜”的程序高手SergioSan,用一个小程序,换来1万美元报酬。

这个阿根廷程序员乐开了花,他在公司工作半年,都赚不到这个数字。

Google惯用“整蛊题”


Google上一轮招聘,今年夏天刚结束。

用的也是一道“科学麻瓜”看不懂的“整蛊题”,而且,堂而皇之挂在硅谷各大地铁站上。9月底,3块15米长的米色广告牌上,简简单单刷着“(在‘e’的数列中所能找到的第一个十位数质数).com”,没有公司名也没有任何广告词。

花了几秒钟,路人才明白,这是一道数学题。自然常数e(2.718281828……)的第一个十位数质数,是目标网站的名字。

好奇分子忍不住用Google搜索起答案来,压根儿不晓得这就是Google出的“硬骨头”考题。

不少人后来在规定时间内,登录上了www.7427466391.com。然而,那不是梦寐以求的终点站,Google恶作剧似的,为“高手”们在半山腰设了个休息的小凉亭。

www.7427466391.com里,贴出一条更令人头疼的数学问题,答出这个问题,能得到进入下一个网页的密码。

跑完数学“马拉松”,7500个“幸存者”走入Google实验室网页,成功投出简历。最后,Google只要了50个人。“光以广告而论,Google也算得上高段!”

波士顿一家广告公司的高级副总裁弗里茨·库恩分析,“目标人群看到广告后会想,‘这是我的语言,那是冲着我来的’;对其他人而言,广告也使Google的形象大大提升。他们可能会想,‘我是得不到这份工作的了。不过,在那儿工作的人真聪明’。”
