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.

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.

Why we started Adaface ->

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.

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 D3.JS Test 将是不可行的.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment D3.JS Test 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.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the D3.JS Test 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.

Reason #7

Detailed scorecards & benchmarks

Reason #8

High completion rate

Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.

This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.

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？
