Adaface ExpressJS Assessment Test is the most accurate way to shortlist 完整的堆栈开发人员s



Reason #1

Tests for on-the-job skills

The ExpressJS Test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

  • 能够设置和配置Express.js应用程序
  • express.js中路由的知识用于处理不同的端点
  • 了解express.js中的静态文件
  • 在Express.js中创建和使用中间Wares的经验
  • 能够在Express.js中使用模板引擎进行动态内容
  • 精通Debuging Express.js应用程序
  • 了解Node.js基础知识
  • 强大的JavaScript编码知识
  • 处理异常和错误的经验
  • 在Express.js应用程序中优化性能的能力
Reason #2

No trick questions

no trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

View sample questions

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

How we design questions

这些只是我们库中有10,000多个问题的一个小样本。关于此的实际问题 ExpressJS测试 将是不可行的.

🧐 Question

Medium

I/O cycle and main module
Event Loop
Try practice test
Review the following NodeJS code:
 image
Pick the correct statements:

A: X will be logged after Y always
B: Y will be logged after X always
C: The order of executing timeout and immediate callbacks is non-deterministic and is bound by the performance of the process
D: In this case, the function calls are scheduled in the main module and not in the I/O cycle
E: In this case, the function calls are scheduled in the I/O cycle so setImmediate is always executed before any timers scheduled in the I/O phase, independently of how many timers are left

Easy

Res methods
Try practice test
If none of the methods (res.download, res.end, res.json, res.jsonp, res.redirect, res.render, res.send, res.sendFile, res.sendStatus) are called from a route handler to terminate request response cycle, what happens to the the client request?
A) Will be left hanging indefinitely

B) Will get an internal server error - 500 

C) Will get a service unavailable error - 503

D) Will be left hanging for a while and then request timeout error - 408

Medium

Phases and Timers
Event Loop
Try practice test
Review the following NodeJS code:
 image
Pick the correct statements:

A: Adaface will be logged after Lovelace.
B: Lovelace will be logged after Adaface.
C: Once the asyncOpThatTakes195ms completes reading the file, it starts executing the callback which takes 10 seconds. Only after this is finished, the event loop will execute the timers that are finished. So the timeout call back will actually be executed after 205 ms even though it is scheduled to be run after 200 ms
D: Once the asyncOpThatTakes195ms completes reading the file, it starts executing the callback. While executing the callback, the scheduled timer becomes ready to be executed. So the runtime executes the timer and then completes processing the callback.

What will the following code output?

A: 24 after 5 seconds and after another 5 seconds, another 24
B: 24 followed by another 24 immediately

D: After 5 seconds, 24 and 24
E: Undefined
F: NaN

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment ExpressJS测试 in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Science behind Adaface tests
Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the ExpressJS测试 from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

About the ExpressJS Online Test

Why you should use Pre-employment ExpressJS Test?

The ExpressJS测试 makes use of scenario-based questions to test for on-the-job skills as opposed to theoretical knowledge, ensuring that candidates who do well on this screening test have the relavant skills. The questions are designed to covered following on-the-job aspects:

  • Express中的路由
  • 设置快速申请
  • 在Express中服务静态文件
  • 在Express中创建和使用Midderwares
  • 使用模板引擎
  • 调试快车
  • Node.JS基本面
  • JavaScript编码
  • Express的身份验证和授权
  • Express中的数据库集成

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

What topics are covered in the ExpressJS Test?

  • Express

    Express中的路由是指应用程序如何处理不同的HTTP请求并将其引导到适当的路由。它本质上将所需的URL映射到相应的处理程序功能或中间件,使其成为构建动态Web应用程序的关键技能。

  • 设置Express Application

    设置Express应用程序涉及安装必要的依赖项,配置应用程序设置以及创建基本文件结构。该技能很重要,因为它为开发和运行Express应用程序的基础奠定了基础。

  • 在Express中使用Express

    在Express中服务静态文件中的静态文件允许应用程序服务于HTML,CSS,CSS, JavaScript和对客户端的其他静态文件。它可以确保正确渲染网页并加载必要的资产,从而使其成为Web开发的重要技能。

  • 在Express </p>

    Middlewares中创建和使用MiddleWares Express中的功能可以访问请求和响应对象。它们可用于添加功能,执行验证,处理错误等等。能够创建和使用MiddleWares对于构建可靠和可扩展的应用程序很重要。

  • 使用模板引擎

    Express中的模板引擎允许通过将模板与数据结合到动态生成HTML页面。他们简化了在服务器上渲染HTML的过程,并启用代码重复使用。理解和使用模板引擎对于开发动态Web应用程序至关重要。

  • 调试Express

    调试Express涉及识别和解决应用程序代码中的问题或错误。它需要使用调试工具理解错误消息,并对代码进行故障排除以确保操作平稳。熟练调试Express应用程序对于提供高质量的软件是必要的。

  • node.js基础知识

    node.js基础知识包括node.js的核心概念和功能,包括事件。 - 驱动的体系结构,非阻滞I/O,模块和文件系统操作。 Node.js基本面的知识很重要,因为Express.js是在Node.js顶部构建的,并了解其在引擎盖下的工作方式有助于构建有效的应用程序。

  • JavaScript编码

    JavaScript编码是指使用JavaScript编程语言编写清洁,高效和可维护的代码的能力。强大的JavaScript编码技能对于使用Express.js开发服务器端应用程序至关重要,并有效地利用了它提供的各种功能。

ExpressJS Hiring Test 常见问题解答

我可以将多个技能结合在一起,为一个自定义评估吗?

是的,一点没错。自定义评估是根据您的职位描述进行的,并将包括有关您指定的所有必备技能的问题。

您是否有任何反交换或策略功能?

我们具有以下反交易功能:

  • 不可解决的问题
  • IP策略
  • Web Protoring
  • 网络摄像头Proctoring
  • 窃检测
  • 安全浏览器

阅读有关[Proctoring功能](https://www.adaface.com/proctoring)的更多信息。

如何解释考试成绩?

要记住的主要问题是评估是消除工具,而不是选择工具。优化了技能评估,以帮助您消除在技术上没有资格担任该角色的候选人,它没有进行优化以帮助您找到该角色的最佳候选人。因此,使用评估的理想方法是确定阈值分数(通常为55%,我们为您提供基准测试),并邀请所有在下一轮面试中得分高于门槛的候选人。

我可以使用该测试的经验水平?

每个ADAFACE评估都是为您的职位描述/理想候选角色定制的(我们的主题专家将从我们的10000多个问题的图书馆中选择正确的问题)。可以为任何经验级别定制此评估。

每个候选人都会得到同样的问题吗?

是的,这使您比较候选人变得容易得多。 MCQ问题的选项和问题顺序是随机的。我们有[抗欺骗/策略](https://www.adaface.com/proctoring)功能。在我们的企业计划中,我们还可以选择使用类似难度级别的问题创建多个版本的相同评估。

我是候选人。我可以尝试练习测试吗?

不,不幸的是,我们目前不支持实践测试。但是,您可以使用我们的[示例问题](https://www.adaface.com/questions)进行练习。

使用此测试的成本是多少?

您可以查看我们的[定价计划](https://www.adaface.com/pricing/)。

我可以免费试用吗?
