9 reasons why

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

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	Solve
Review the following NodeJS code: 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	Solve
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	Solve
Review the following NodeJS code: 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.
Medium Async Await Promises Promises Async-Await	Solve
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 C: 24 immediately and another 24 after 5 seconds D: After 5 seconds, 24 and 24 E: Undefined F: NaN G: None of these
Medium Bitcoin prices Axios Promises	Solve
Review the following JavaScript code and pick the correct options: Assume that the API returns a successful 200 response code and a JSON object as the response body. What would the value of ‘a’ be after the code is executed?
Medium My Module Scope	Solve
What will the output of the following JavaScript code be?
Medium Promise Resolve Promises Async-Await	Solve
What does the following code output?
Easy Throw, Try, Async Promises Async-Await	Solve

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

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。
