招聘时测试 HTML/CSS/Javascript 技能

在招聘前端开发人员时，您应该测试哪些特定技能和实践?评估他们在 HTML、CSS 和 Javascript 方面的技能的好指标是什么?

显然，无表语义 HTML 和纯 CSS 布局可能是关键技能.但是具体的技术呢?他/她应该能够毫不费力地模拟多列布局吗?CSS精灵?等高(或人造)列?HTML 标签的选择是否重要(即过于依赖 <div>)?他们应该能够(用文字)解释花车是如何工作的吗?

那么 JavaScript 技能呢?框架经验(jQuery、Prototype 等)有多重要.今天?

显然，职位的详细信息和他们将从事的工作的网站最能说明需要哪些技能.但我想知道在为候选人创建测试时，人们可能会认为哪些特定技能会破坏交易(或制造商).

解决方案

当我面试客户端开发人员职位的人时，我试图弄清楚:

<上一页>1) 了解 DOM(那是什么，它与 HTML 有什么关系等)2) 理解 XML/命名空间3) 理解 JavaScript(面向对象?否则如何)4) 了解组件化方法(XBL、HTC) - 加5)理解OO原理6) JavaScript 闭包7) 浏览器内存泄漏

我马上给出的唯一一个简单的测试用例:

<上一页><脚本类型="文本/javascript">变量 a = 1;</脚本>

我建议受访者用技术术语解释那句话.

我还检查了对 Web 技术当前状态的总体认识，除其他问题外，我建议设计一个 Web 浏览器，建议受访者选择他将投入到他的全新生物中的技术，提出可能当前客户端平台中缺少.

When hiring a front-end developer, what specific skills and practices should you test for? What is a good metric for evaluating their skill in HTML, CSS and Javascript?

Obviously, table-less semantic HTML and pure CSS layout are probably the key skills. But what about specific techniques? Should he/she be able to effortlessly mock up a multi-column layout? CSS sprites? Equal height (or faux) columns? Does HTML tag choice matter (ie, relying too heavily on <div>)? Should they be able to explain (in words) how floats work?

And what about javascript skills? How important is framework experience (jQuery, Prototype, etc). today?

Obviously, the details of the position and the sites they'll be working on are the best indication of what skills are needed. But I'm wondering what specific skills people might consider to be deal-breakers (or makers) when creating tests for candidates.

解决方案

When I interview people for a position of Client-Side developer I try to figure out:

1) Understanding DOM (what is that, how is it related to HTML etc)
2) Understanding XML/namespaces
3) Understanding JavaScript (object-oriented? what otherwise)
4) Knowing approaches to componentization (XBL, HTC) - plus
5) Understanding OO principles
6) JavaScript closures
7) Memory leaks in browsers

The only simple test case I give right away:

<script type="text/javascript">
var a = 1;
</script>

I suggest interviewee to explain in technical terms that line.

And I also check on overall awareness of the current state of the Web technologies, among other questions I suggest designing a web-browser where interviewee is suggested to pick technologies he would put into his brand-new creature, suggest ones that might be missing from the current client-side platform.
