If you were to give recommendations to your "little brother/sister" on things that they need to do to become a data scientist, what would those things be?
I think the "Data Science Venn Diagram" (http://drewconway.com/zia/2013/3/26/the-data-science-venn-diagram) is a great place to start. You need three things to be a good data scientist:
| library("shiny") | |
| x <- runApp(shinyApp( | |
| fluidPage( | |
| "Password:", | |
| tags$input(id = "password", type = "password"), | |
| actionButton("done", "Done") | |
| ), | |
| function(input, output) { | |
| observe({ |

此repository包含了一些前端開發的面試問題，來審查一個有潛力的面試者。這並不是建議你對同一個面試者問上所有的問 (那會花費好幾小時)。從列表中挑幾個題目，應該就夠幫助你審查面試者是否擁有你需要的技能。
Rebecca Murphey 的 Baseline For Front-End Developers 也是一篇很棒且值得讀的文章在你開始面試之前。

Prereq:
apt-get install zsh
apt-get install git-coreGetting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh
wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
