Adaface Data Analysis Assessment Test is the most accurate way to shortlist 数据分析师s



Reason #1

Tests for on-the-job skills

The Data Analysis 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:

  • 了解数据建模的基础知识,包括实体和关系
  • 应用数据分析技术,例如聚合和统计数据
  • 应用业务分析基础
  • 使用图表和图表解释数据
  • 使用SQL执行数据查询并使用数据库
  • 执行数据操作,包括预测和异常
  • 进行数据调查,包括相关和排名
  • 利用诸如Excel之类的流行数据工具
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.

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.

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 数据分析测试 将是不可行的.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment 数据分析测试 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 数据分析测试 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.

Data Analysis Hiring Test 常见问题解答

我可以使用数据分析师测试招聘数据科学家吗?

是的,如果您的职位描述与数据分析师的要求紧密匹配。您还可以检查我们的标准[数据科学家测试](https://www.adaface.com/assessment-test/data-science-test),以进行更集中的测试。

我可以在数据分析测试中评估Python或R吗?

是的。您可以进行三个测试的变体:

  • 对于数据分析师(Python)角色:与标准问题集一起,测试将有Python MCQ问题和Python编码问题
  • 对于数据分析师(R)角色:与标准问题集一起,测试将有R MCQ问题和R编码问题
  • 对于候选人可以知道** python或r **的数据分析师的角色:除了标准问题集外,候选人将被要求在Python和R之间选择其首选的编程语言,然后,将向候选人询问MCQ和MCQ和编码有关选定的编程语言的问题。

为了了解要评估Python或R技能的问题,您可以回顾我们的标准[Python在线测试](https://wwwww.adaface.com/assessment-test-test/python-online-test)和[R在线测试](https://www.adaface.com/assessment-test/r-online-test)。

我可以在数据分析测试中评估Excel技能吗?

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。
