9 reasons why

Adaface RxJS Assessment Test is the most accurate way to shortlist 软件开发人员s

Reason #1

Tests for on-the-job skills

The RxJS 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:

能够有效理解和使用反应性编程概念
能够与可观察物一起工作并对其进行操作
能够在RXJ中使用各种操作员进行数据转换
能够与受试者一起处理多个订户
能够将转换操作员应用于可观察到
能够使用组合操作员组合可观察的物品
能够在RXJ中有效处理错误
能够在反应流中处理反压
能够使用RXJ进行反应代码编写测试
能够使用RXJS库编写JavaScript代码

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 RXJS测试将是不可行的.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment RXJS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 RXJS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 RxJS Online Test

Why you should use Pre-employment RxJS Test?

The RXJS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:

在现实世界中使用反应性编程概念的能力
了解可观察到的，它们的工作方式以及如何创建它们
在RXJS中与各种操作员及其用例的经验
主题的工作知识及其在事件处理中的作用

What topics are covered in the RxJS Test?

可观察到：
可观察到可观察到的是反应性编程的基本概念。它们代表可以随着时间的时间观察到的数据流。通过订阅可观察到的东西，开发人员可以对流的变化做出反应并相应地执行操作。测量测试中的这一技能有助于评估候选人对可观察物的理解及其与他们一起处理异步事件和数据的能力。
操作员：
在反应性编程中操作员是反应性编程的功能操纵可观察的流并产生新的所需输出流。它们使开发人员能够在可观察到的情况下转换，过滤，组合和执行其他各种操作。测试中这种技能的测量有助于评估候选人在使用不同操作员方面的熟练程度，以及他们对如何将其应用于有效解决现实世界问题的理解。
主题：
主题是一种特殊的可观察类型，可以同时允许值排放和消耗。它既是观察者又是可观察的，它在应用程序的不同部分之间提供了桥梁。测试中这种技能的测量有助于评估候选人对受试者的理解及其用于在系统的组件或不同部分之间进行通信的能力。
转换操作员：
转换操作员在RXJ中，开发人员可以将可观察到的流发出的数据转换为不同的格式或结构。它们有助于简化数据操纵并启用逻辑转换，然后再消耗数据。测试中这种技能的测量有助于评估候选人有效地使用转型操作员并了解其应用程序范围的能力。
错误处理：
RXJS中的错误处理涉及处理。异步操作期间可能发生的错误。它包括错误传播，捕获和处理机制，以确保正确处理错误并防止数据流中断。测试中这种技能的测量有助于衡量候选人在RXJ中实施错误处理技术的知识和熟练程度，从而确保其代码中的鲁棒性和可靠性。
背压：
背压是一种流程。 RXJ中的控制机制使消费者可以控制他们从生产者那里接收数据的速度，从而防止压倒性或资源耗尽。它确保以有效处理的速度消耗数据。测试中这种技能的测量有助于评估候选人对背压概念的理解及其实施适当策略来管理数据流和防止瓶颈的能力。
使用RXJS进行测试：
测试测试RXJS涉及编写使用反应性编程和可观察到的代码测试。它包括嘲笑可观察到的，模拟事件以及验证预期行为。有效的测试有助于确保反应性代码的正确性和可靠性。测试中此技能的测量有助于评估候选人在测试RXJS代码方面的熟练程度及其为反应性应用程序编写全面可靠的测试用例的能力。
JavaScript编码：
JavaScript编码参考。具有编写清洁，高效和可维护的JavaScript代码的能力。它涉及应用最佳实践，有效地利用语言功能以及遵循编码标准。测试中此技能的测量有助于评估候选人的JavaScript编码技能以及其编写可读性，性能和可扩展的高质量代码的能力。
