Adaface Power BI Test is the most accurate way to shortlist Power BI开发人员s



Reason #1

Tests for on-the-job skills

The Power BI Online 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:

  • 连接到数据源并导入
  • 进行数据争吵和转换
  • 创建和优化数据模型
  • 写有效的DAX公式
  • 设计视觉吸引人的主题和可视化
  • 构建互动报告
  • 发布和分享报告
  • 有效利用Power BI桌面
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 Microsoft Power BI测试 将是不可行的.

Data Filtering
Report Development
M Language
Data Visualization
Try practice test
You are creating a Power BI report where users need to dynamically filter data based on a range of dates. The report has a Sales table with columns Date, ProductID, and Amount. You decide to use a Power Query parameter to allow users to select a start and end date, which will then filter the Sales table accordingly. The parameter is named DateRange and has a type of List. You need to write a Power Query M formula to filter the Sales table based on the selected date range. The DateRange parameter contains two dates: the first item is the start date, and the second item is the end date. How should the M formula be structured to achieve this functionality?
A: Table.SelectRows(Sales, each [Date] >= DateRange{0} and [Date] <= DateRange{1})

B: Sales{[Date] >= DateRange{0}, [Date] <= DateRange{1}}

C: Table.FilterRows(Sales, each [Date] >= List.First(DateRange) and [Date] <= List.Last(DateRange))

D: Table.SelectRows(Sales, each [Date] >= List.First(DateRange) and [Date] <= List.Last(DateRange))

E: Filter.Table(Sales, [Date] >= DateRange{0}, [Date] <= DateRange{1})

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Microsoft Power BI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 Microsoft Power BI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.
