Catch Of The Day的developer招聘题

kr2000

这是在招聘广告里看到的,要先回答才能申请
1.How many Airbus A380s can fit into a 16,000sqm warehouse? What assumptions does your calculation make?
2.Analyse a page or feature (e.g. signup, checkout) on one of our websites. How would you improve the conversion rate of the page or feature?
3.You receive two customer orders at the exact same time for the exact same product. There is only enough stock of the product to fulfil one order. How would you resolve this situation?

这不是招聘，这是brain storm他们的prod issue.

这说明程序写的有问题，concurrent control没做好

搞这么多团购，有意思吗？

2.  Split test for different features, and pick the higher conversion rate choice.  color of checkout, size of checkout etc.
2.  Try to buy this product from other websites or retail asap, we know COTD delivery time is amazing slow.....                           And,  for website, add a reserve product for this issue. That means when stock appears 1, there's actually 2 in the warehouse.

咱们坛子里真有高人，赞一个！！

2.尽量减少signup/checkout的steps是关键，上一个工作做过有关remove one step out of checkout process, conversion rate增加了6%.
3.我们用stockoutshreshhold作为reserved quantity, COTD这方面显然做的很不好，看看社区对他们的评价就知道了。

对于问题3，哪个customer愿意等下一批货到的话，就送一张购物券。

"我们用stockoutshreshhold作为reserved quantity..."

我对这个问题有点兴趣。 你的Reserved Quantity是凭经验手工设定的还是根据商品本身的情况和销售历史动态生成的？

“对于问题3，哪个customer愿意等下一批货到的话，就送一张购物券。”

这样的问题是没有答案的。思考的过程才是招聘人所看重的。每一个方案都是建立在一些假设的基础上，至于那个方案最优，还是要对BUSINESS进行更细致的分析。

第二第三个都是BA，product manager 该回答的问题
看来cotd也是个小店，一个developer进去要兼顾很多事情

Cotd已经成黑店了，迟早要倒闭的。

我昨天去bunings看到cotd买的那套makita的钻头的，全价才29
Amzone 卖18+11
Cotd 卖 25 + 10

我猜cotd没准就是一人给一随机数，谁大谁得

对第三个问题很感兴趣：
最简单的方法就是把两个Order都Refuse,等下一个不冲突的Order.
