Adaface Data Modeling Skills Test is the most accurate way to shortlist candidates



Reason #1

Tests for on-the-job skills

The Data Modeling 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.

The Adaface Data Modeling Online Test screens candidates for the typical skills recruiters look for Data Modeler roles:

  • Experience in an enterprise environment developing relational databases
  • Strong analytical, data profiling and problem-solving skills
  • Knowledge of facilitation and conflict resolution processes
  • Experience developing models for Business Intelligence solutions

The insights generated from this assessment can be used by recruiters and hiring managers to identify the best candidates for Data Modeler roles. Anti-cheating features enable you to be comfortable with conducting assessments online. The Data Modeling Online Test is ideal for helping recruiters identify which candidates have the skills to do well on the job.

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.

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.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Data Modeling Skills 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 Data Modeling Skills 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.

About Data Modeler Roles

The process of generating a simplified representation of a software system and the data pieces using text and symbols to represent the data and how it flows is known as data modelling. Data models serve as a blueprint for creating a new database or reengineering an existing one.

A Data Modeler are in charge of creating data models. They convert business information into models by interacting with business customers and seeking their needs, then iteratively refining the conceptual, logical, and physical data models.

Typical Data Modeler responsibilities include:

  • Engaging the business users to assess their information needs
  • Developing logical data models and validate the models
  • Transforming logical representation of the models into a physical representation
  • Collaborating with BI and Analytics teams on creating the optimized, reusable semantic models, complete with metadata and lineage information

テストスコアを解釈するにはどうすればよいですか?

留意すべき主なことは、評価が選択ツールではなく排除ツールであることです。スキル評価が最適化され、技術的にその役割の資格がない候補者を排除するのに役立ちます。これは、役割の最良の候補者を見つけるのに役立つために最適化されていません。したがって、評価を使用する理想的な方法は、しきい値スコア(通常は55%、ベンチマークを支援します)を決定し、インタビューの次のラウンドのしきい値を超えてスコアを上回るすべての候補者を招待することです。

このテストを使用できますか?

各ADAFACE評価は、職務記述書/理想的な候補者のペルソナにカスタマイズされます(当社の主題の専門家は、10000以上の質問のライブラリからあなたの評価に適切な質問を選択します)。この評価は、あらゆる経験レベルでカスタマイズできます。

すべての候補者は同じ質問を受け取りますか?

私は候補者です。練習テストを試すことはできますか?

いいえ。残念ながら、現時点では練習テストをサポートしていません。ただし、[サンプルの質問](https://www.adaface.com/questions)を使用するには、練習できます。
