When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

	import { useState } from 'react';

	export function useCounter(initial = 0) {
	const [count, setCount] = useState(initial);

	return [count, () => setCount(count + 1)];
	}

	const warningDescCSS = 'font-size: 18px;';

	## Global install of the app generator
	npm install -g create-react-app

	## Setup the app (first-time only)
	create-react-app my-app
	cd my-app
	git init

	# Create the Heroku app; requires free account at https://www.heroku.com/
	heroku create -b https://github.com/heroku/heroku-buildpack-static.git

	var request = new Request('https://hooks.slack.com/services/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', {

	headers: new Headers({'Content-type': 'application/json'})
	});
	fetch(request).then(function(response) { console.log(response)});

	main() {
	# Use colors, but only if connected to a terminal, and that terminal
	# supports them.
	if which tput >/dev/null 2>&1; then
	ncolors=$(tput colors)
	fi
	if [ -t 1 ] && [ -n "$ncolors" ] && [ "$ncolors" -ge 8 ]; then
	RED="$(tput setaf 1)"
	GREEN="$(tput setaf 2)"
	YELLOW="$(tput setaf 3)"

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console

	准备：
	libxml2 2.6.18 or above from http://www.xmlsoft.org/
	libxslt 1.1.x or above from http://www.xmlsoft.org/
	先查看当前系统中是否有安装libxml2，libxslt这两个库，如果没有请到下面的网站中去下载安装
	# sudo apt-get install libxml2-dev
	# sudo apt-get install libxslt1-dev

	由于安装pgAdmin3需要wxGTK，所以也要下载wxGTK
	wxGTK 2.8.x from http://www.wxwidgets.org/
